The present invention relates to a protective element for the media, with the effect of the layer to the media with such a protective element, and method of manufacturing such a protective element.

The media, such as valuable or personal documents, first of all ID cards, credit cards or passports, or other valuable objects, such as merchandise, in order to protect them against forgery supply protective elements, which allow to verify the authenticity of the object and simultaneously serve as protection against illegal or unauthorized copying. In addition, the protective elements often create distinct visual (optical) impression and therefore, in addition to performing its primary function of protective equipment is sometimes used only as decorative elements on such media or on their packaging. The protective element may be embedded in the material of such media, for example in the material of the banknote or smart card, or may be made in the form of a self-supporting conversion element, for example, in the form of a sticker or label, which, after its manufacture is placed on the protected from a fake media or other object. However, this alternative protective element can also integration of the ed in the media in the process of its manufacture.

Under (material) media according to the present invention refers primarily banknotes, stocks, bonds, certificates, warrants, checks, expensive tickets, but also refers to other vulnerable forgery papers such as passports or other personal documents, executed in the form of maps media, mainly credit cards and smart cards, as well as protective elements for protecting products against counterfeiting, such as labels, printing, packaging and similar items. The concept of "media" covers are also not suitable for the treatment of predecessors or semi-finished products such media, which, for example, in the case of counterfeit paper presented in quasiresonant and which subsequently undergo further processing.

Such protective elements to prevent their forgery or imitation, for example, by reprographic reproduction on high quality multicolor Photocopying devices can have with optically variable properties of the elements that, when viewed at different angles to create different optical (visual) experience. There are various technologies create the effect of layers exhibiting such optically variable is ffecti. For example, for this purpose you can use the optical interference layers in the form of a continuous layer or in the form of pigments. Such interference layers are usually thin-layer structure, which, for example, when it is executed multi-layer formed of a reflective layer, an absorbing layer and one or more located between the dielectric separator layers, and is made, for example, on the basis of mica, SiO2or Al2O2. Such interference layers according to the number of dielectric layers is designated as one - or multi-layered. Printing ink formed by interference layer pigments (interference pigments are available, for example, by Merck KGaA under the name Iriodin® single-layer structure or Colorcrypt® (multilayer structure). In addition, printing inks with multilayer interference pigments are produced by a company SICPA under the name OVI®. Instead of the interference layers or formed by pigments (interference pigments) can also be used cholesteric liquid crystals. They are represented, for example, in the form of liquid silicone polymers or contains in the form of pigments in the so-called STEP-colors (from the English. "Shimmery Twin Effect Protection"). In addition, different (variable) optical the impression when viewed at different angles also create holograms which are usually obtained by thermal vacuum deposition (thermal vacuum deposition of metal layers or a diffraction grating.

Different visual impressions a person may create a so-called color Kipp effect that different angles of view allows you to see different hues. Different visual impressions can also create the effect of the layer at a certain angle of view is completely transparent and therefore not visible to man, whereas a different angle of view (angle manifestations optical effect) is seen painted in a certain color tone. A similar effect layers are often cast-pearl, i.e. have a pearly luster, which is typical, for example, shells or mica. Usually, such pigments, which show the effect of color change when changing the direction of viewing, call goniochromism pigments.

Single-layer interference layers and printing inks with a single-layer interference pigments or liquid crystal pigments often have considerable translucent all angles of view, and therefore the effect of the layer when it is viewed at an angle manifestations optical effect creates a relatively weak color impression, barely visible to the human eye. For this reason, the effect of SL and with high light transmission (translucent) to improve the distinctiveness of color change is mainly put on dark or black background. In contrast, the interference layers with a multi-layer structure and a multilayer interference pigments have a low light transmission (translucent) and sometimes are completely opaque.

According to EP 0317514 A1 high translucent applied layer of paint Iriodin used as protecting against forgery sign of authenticity. The layer of paint Iriodin applied on a black background and therefore when viewed genuine protective characteristic angle manifestations optical effect can visually perceived color impression created by the applied layer of paint Iriodin. Multi-color photocopier is not able to recognize such paint Iriodin due to the weak intensity of its color, but also because of the scan image in the reflected light at the right angle under which the coat of paint Iriodin transparent, and therefore copies only black background. For this reason, the copy does not create optically variable color impression.

To improve the visual distinctiveness relatively weak color impression created by the layer of paint Iriodin, in EP 0490825 A1 it is proposed to use several adjacent each other stripes of paint Iriodin creating different color impressions, which generally improves their visual perception.

From EP 0863815 know Yes is it the numbering of the layer with optically variable properties on top of the printed information. Its aim is to provide a manifestation of the optically variable effect on the fine-structure phase, for example, only within the narrow lines that cannot be realized by a method of screen printing is typically used for applying the ink with optically variable properties, due to its characteristic small spatial resolution. To this end such finely structured areas such as gelosi, it is proposed to provide printed information and to apply them, for example, by the method of metallographic printing. Color printed information and background is chosen so that the optically variable effect solid located above the effect of a layer of visually perceived, for example, finely-structured parts, printed metallographic printing.

Ink with optically variable properties, commonly used for the manufacture of protective elements which are difficult to reach potential falsifiers. However, similar at least for the inexperienced or inattentive person of color impressions can be achieved using other substances, for example, in the nail Polish. Thus it is possible to forge or imitate not only one color, but two - and multi-colour prints ink with optically variable properties

The present invention was used to develop the protective element with improved testability of authenticity and with a high degree of protection against forgery. Another object of the invention was to propose a suitable storage medium, and also to develop a method of manufacturing such a protective element.

This task is solved by a protective element, media, and method of manufacturing such a protective element, as claimed in the respective independent claims. In the respective dependent claims presents the preferred options for its implementation.

Proposed in the invention, the protective element has a paint layer and the effect layer. The paint layer has a color tone, which is visually discernible, and which does not change when the angle of view, for example, when the inclination of the protective element. The effect is a layer mainly transparent when viewed at a first angle, for example at right angle, and this angle of view, but preferably not visible, if it is, as is customary in the following description, is in the direction of looking over the paint layer. Thus, when viewed at the right angle of view creates the color impression of the advantages the government is determined solely hue of the underlying paint layer. The expression "mostly clear" according to these materials means that the effect of the layer because of its complete transparency, respectively exceptionally high B.C. (light transmission) is not visible, respectively barely visible at a certain angle of view.

When viewed under a second angle, the so-called angle manifestations optical effect, a layer also becomes visible color tone, with both color impressions, in principle, are superimposed one on another. According to the invention the effect of the layer has a color tone which creates more contrast with the hue of the paint layer. In a preferred embodiment, the color tone of the paint layer and the effect of the layer are complementary colors.

The definition of complementary colors depends on the color space. For example, the magnitude of the relative vidnosti monochromatic radiation (relative spectral luminous efficiency for photo-optical (day) vision must in every place of the visible spectrum to give in the amount of 1. Thus, according to this definition additive mixing complementary colors produces white (see "Lexikon der Optik", Ed. by Harry Paul, published by Spektrum Akademischer Verlag GmbH, Heidelberg, 2003, S. 360). Unlike the strict mathematical definition in the present from which retene is the set empirically fact, when looking translucent color layer, which is located on the underneath, for example, an opaque paint layer, perceived by the human eye color impression is determined principally by the hue of the upper, translucent layer mainly in the case when the concern mainly of additional colors. Both color tone may slightly differ from the strict definition of complementary colors that in the following description is expressed by the term "more contrast". When viewed at an angle manifestations optical effect layer forms a similar color, translucent layer. In this case, when viewed at an angle manifestations of the optical effect of the human eye perceives predominantly color tone effect layer. Same color tone lower paint layer to a considerable extent, and in the ideal case completely disappears and consequently almost or completely stops visually perceived.

Thus proposed in the invention is the use of colors that create in relation to each other for more contrast, facilitates the transition from the first angle to the corner of the manifestations of the optical effect of "weakening" or "suppression" color tone of the paint layer and increased the tion" or "dominance" color tone effect layer. In other words, the protective element has a binary (double) Kipp effect, because when viewed at a first angle of view in the ideal case only seen the color tone of the paint layer, when viewed at an angle manifestations optical effect in the ideal case is only visible color tone effect-layer.

To achieve binary Kipp effect and thereby to fully suppress the color tone of the paint layer hue effect-layer proposed in the invention, the choice of colors is preferred also because the angle of the manifestations of the optical effect of the reflection spectrum located below the paint layer is additionally suppressed (absorbed) located above the effect layer with at least approximately the hue and mixed with matching colour tone effect-layer, resulting in inhibited, respectively, mixed hue (image) paint layer ceases to be perceived by the human eye. The same image, reproducible effect layer becomes visible and dominates this over the hue (image) located below the paint layer.

As the effect of the layer can, in fact, use many of the known from the prior art layer with optically variable properties. Most preferably, about whom, however, to use the interference layers with a single layer structure of ink from the single-layer interference pigments, such as paint Iriodin® Merck or multilayer interference pigments, for example, paint Colorcrypt® Merck and paint with cholesteric liquid crystal pigments. Produced, for example, Merck pigments Iriodin® usually are pigments with mica core provided with an interference layer, primarily from titanium dichloride, ferric chloride or both of them in their combinations with each other.

The thickness of the interference layer is chosen such that it is its size was in the range of wavelengths of the desired color (1st order) or repeatedly exceeded the desired wavelength (2nd, 3rd, 4th and subsequent orders). Usually pigments, in which the thickness of the interference layer is many times higher than the desired wavelength and which is often referred to as "pigments of the highest order", richer in colour than the so-called pigments 1-th order. Typically, the human eye is able to perceive only some of the characteristic color only under a certain angle. Produced, for example, Merck pigments Colorcrypt® usually are pigments with a core of silicon oxide, is provided with an interference layer, which has the multiple layers, first of all intermediate layers. Therefore, depending on the thickness of the individual layers of the human eye perceives different angles of view are different colors, but only in a relatively narrow range of wavelengths about a particular centroid wavelength. In contrast, pigments OVI®, respectively paint OVI® company SICPA are dependent on view angle color Kipp effect in a relatively wide wavelength range.

Manufactured by Merck pigments Colorcrypt® significantly harder and more expensive to manufacture than also produced by Merck pigments Iriodin®, and so much more them that keeps rigged from the use of such pigments because of their high cost, and thus further increases the degree of protection against forgery, provide proposed in the invention of protective elements with pigments Colorcrypt®. In addition, the pigments Colorcrypt® Merck allow one to identify them under a microscope that when checking with suitable for this purpose AIDS can serve as proof of authenticity. Obviously, above or preferably applied effect pigments are presented only as examples and should not be construed as limiting the scope of invention.

The use of interference layers with a single layer structure Iriodin® and Colorcrypt® Merck, and paints with cholesteric liquid crystal pigments are particularly preferably primarily insofar as they all angles of vision exhibit high light transmission under the first angle of view, i.e., for example, at a right angle of view is usually completely transparent when viewed at an angle manifestations optical effect, despite its translucent, showing the presence of a color tone is high enough intensity.

To achieve sufficiently intense color tone effect layer, for example, pigment Iriodin® is required to apply in sufficient quantities. The covered surface in the ideal case should be provided mainly by a continuous layer of pigment Iriodin®. This is achieved by applying the effect paints Iriodin® number, an average of about 9 g/m2(in dry state), which results in pigment layer thickness of about 30 μm. A further increase in the intensity of the color tone is achieved by calendering the basics, because the flat pigments due to this, even better oriented in the same plane.

Under the underlying paint layer mainly refers to the opaque layer, in accordance with the color tone of the protective element is not dependent on an applied basis. On the other hand, in the case where such inter is Astia with the background, for example, having a different color or translucent basis, strive to achieve intentionally, you can also use translucent, i.e., translucent paint layer.

The effect of the layer in the preferred embodiment, is located on a paint layer, directly bordering it. On the other hand, between the colored layer and the effect layer can also include other translucent or transparent layers.

In order to ensure a good visual appearance of the proposed invention in binary Kipp effect and to achieve the above-described "suppression" color tone of the paint layer and "prevalence" color tone effect-layer paint layer and the effect of the layer is preferably in the form of separate layers, and not, for example, in the form mainly one homogeneous layer, which created the color impression is determined by the mixture of colors that are created according to the invention each of the paint layer and the effect of the layer.

In a preferred embodiment, the effect of the layer is subjected to spatial structuring, i.e. put separate patches on the lower paint layer, reproducing in this way some of the visually perceived information, the display effect layer. To this end, in effect layer may be provided, for example, missing part ("cut"), which is preferable, for example, p. and education, the effect of the layer of cholesteric liquid crystal pigments. In accordance with this, the effect of the layer when viewed at an angle manifestations optical effect only on the first plot shows the presence of the color tones, additional to the paint layer. In a preferred embodiment, the effect of the layer along with a missing part, or instead has a second area on which the effect of the layer when viewed at an angle manifestations optical effect manifests the presence of the second hue that blends with the color tone of the paint layer. The angle of manifestation optical effect on the first and second plots the effect of the layer thus identical or there is at least one angle at which the first and second areas simultaneously show the presence of the above-described color tones and which in this case is indicated by the angle manifestations optical effect.

Under the color tones that harmonize among themselves, according to the present invention refers to colours, which have at least the same main color, primarily the same main color as the main component, and therefore similar. In addition harmony between the colors are usually comparable lightness and/or saturation, which often refers primarily to offer in the invention of the paint layer.

Since the color tone of the second part of the effect-the Loya in the preferred embodiment, is in harmony with the color tone lower paint layer, when viewed at an angle manifestations of the optical effect of the color tone of the second segment of the effect layer and the color tone of the first section the effect of the layer also create additional contrast.

Because the second separate area effect layer when viewed at an angle manifestations optical effect mainly manifests the presence of the color tones in harmony with the below placed colored layer, the effect of the layer increases in this area of the color impression, which is created below the colored layer located.

In one embodiment, for the formation of one of the sections the effect of the layer, especially the first section, use the layer having high transparency of the ink with optically variable properties, preferably a layer of paint Iriodin, whereas for the formation of another part of the effect layer, especially its second section, use the translucent layer or, if necessary, even opaque paint, preferably the layer obladaushiy high covering power of the paint Colorcrypt or paint OVI. Instead of ink with optically variable properties on the second site the effect of the layer can also be used shiny lacquer. However, the two separate plot effect layer in the ideal case are characterized by an identical angle manifestations optical effect and the same range of angles WR is tion, where possible, the visual perception of each of the color impressions created both plots the effect of the layer.

In a preferred embodiment, the paint layer also has at least two sections, which create different color impressions. Moreover, the color tone different areas of the paint layer in the preferred embodiment, are in harmony with each other.

Thanks to the use of multiple colored areas in the paint layer are clearly visible to the human eye at least under the first angle of view, i.e., for example, at right angle. On the other hand, in connection with the requirement that the different parts of the paint layer should be in harmony among themselves, when viewed protective element at an angle manifestations optical effect all areas of the paint layer, and thus the entire paint layer are hidden first, create additional contrast plot effect layer, and the second, in harmony with the land. Thus the second part of the effect layer, the color tone of which harmonizes with the color tones of the paint layer, the reflection spectrum characteristic of the paint layer, increasing the range of the reflection characteristic of the effect layer. In other words, slightly different color tones different areas of the paint layer within vtoro what about the plot of the effects of the layer is added to another, preferably clearly more intense hue. In the second separate area effect layer when viewed at an angle manifestations optical effect overshadows the slight difference in the colours below are located in different areas of the paint layer, which the human eye as a consequence barely discerns, and preferably completely ceases to distinguish as different parts. Similarly when viewed at an angle manifestations of the optical effect of the color tone of the first section the effect of the layer obscures differences in the spectra of the reflection characteristic of the different areas located below the paint layer. Moreover, the color tone of the first section the effect of the layer creates an additional contrast with several harmony between the colors of different parts of the paint layer.

The colored areas of the paint layer can be formed, for example, by applying layers of paint of different colors or by applying the paint in the form of rasters with different parameters, i.e., in the form of different raster structures. So, for example, on one site provide a density of halftone dots, and the other section provide different density of halftone dots or put a paint solid layer, resulting in the presence of raster patterns creates a color in echallenge, the color tone which is a mixed color tone produced as a result of mixing paint colors, printed with halftone dots, and the background color, for example, the basics. Mixed color will depend on the relative area of halftone dots put paint, for example, their density and size. In accordance with this harmony between the colored sections of the ink layer can also be formed using only one color.

In a preferred embodiment, in the ink layer and in the effect layer different parts of their areas directly adjacent to each other in such a way that the effect layer and the paint layer (without taking into account possible rasterization) applied as a continuous layer. For this, different parts preferably be applied to the individual stages of printing during a single printing process that ensures a low error in the wiring between the areas of both layers.

When such printing effect layer and the paint layer as a continuous layer different parts of each of them visible to the human eye only on the basis of differences in their colors. This is, for example, further reduction of visual distinctiveness areas of the paint layer at an angle manifestations optical effect as a result of their above Setevaya areas of effect-SL is when I viewed the protective element at an angle manifestations optical effect. In the case where the areas of the paint layer to form some information for visual perception, it is possible by tilting the angle of the protective element to hide, making it invisible to humans when viewed them protective element at an angle manifestations optical effect.

In a preferred embodiment, the first and second effect layer also form the second information, different from the first information, reproducible paint layer. Because the first information, reproducible colored layer, for example, visually readable under direct vision angle, when viewed at an angle manifestations optical effect disappears and is replaced with the second information, reproducible effect-layer, with the slope of the protective element is a discrete change of the first information to the second, and preferably is a complete change of the first information to the second.

It is preferable to continue to provide one, and other information of a similar design or graphic means, for example, by presenting any information in two colors, for which the effect of the layer, as well as the paint layer should have only two sections. In addition, it is preferable to provide one, and other information, for example, the strokes of uniform thickness, i.e., areas with similar PR the spatial dimensions.

In this case, the above-described binary Kipp effect leads to a discrete change from one information to another. However, such a change from one information to another occurs only when described above, the purposeful selection of color tones. The complete absence of change one information to another, or what is happening not only completely change one information to another, it is easy to detect, even by inexperienced persons. However, a potential falsifier extremely difficult to simulate such a precise selection of the color tones, because, first, the respective inks are not in the public domain, and secondly, used the rest to simulate such optically variable effects products, such as nail Polish, not able to create a similar effect of a discrete change of the image.

Preferably next to information, reproducible effect layer, and information, reproducible layer of colorful, had meaningful content and, for example, instead of the abstract was presented in easily person-specific (graphics) image. In the preferred embodiment, both of these images clearly differ and are also clearly different semantic content. For example, one of the two images can be a presented in a simple form, a stylized image of kotorogo object, such as, for example, crown, animal, head of the animal, a plant, a well-known symbol or other similar object, and another image can represent, for example, an image number, reflecting the par value or the image of the individual letters, preferably a single letter. For fast, easy visual perception of such images preferably further, the lack of any fine structure. Additionally around such images can be provided by distracting ("nuisance") background structure, which further reduces the visual appearance of respectively other suppressed or hidden image. In addition, both images preferably have approximately the same spatial dimensions.

Such a change of the image contributes to the visual distinctiveness of a discrete change one information to another when the slope of the protective element in one and the other side to change the angle between the first angle and the angle of manifestation optical effect, because the mind is "committed" to such easily and segmentectomy images and therefore mentally suppresses may still persistent, unwanted color differences in the suppressed or hidden image. This is due to the fact that p and the slope of the protective element along with the change of color is subjective dominant for a person to change a graphic image.

Preferably next to a binary change from one information to another, accordingly one image to another occurred when the slope of the protective element only for a few angular degrees, for example, when the tilt 1°, 2°, 5°, 10° or 20°. Such a sharp transition from one image to another preferred to provide easy visual distinction Kipp effect, as well as easy visual distinction of different information.

To ensure easy visual distinction and the ability to easily scan images can be further facilitated, advanced typing them again nearby the effect of the layer, respectively paint layer that enables simularities. In accordance with this person may, in such case, it is easy to check that plays there, for example, the effect of the layer at an angle manifestations of the optical effect of the image, optionally printed near the protective element.

In another preferred embodiment, the paint layer and the effect of the layer located on top of each other and combined with each other. Thanks for the person on the information carrier is formed clearly limited, visually legkoatletka area, in which there is a discrete change from one information to another, accordingly one graphical image to another.

In predpochtitel the nom version of the effect layer and the paint layer are precise registration relative to each other, achievable when printing one and another layer on the separate stages of a single printing process.

In another preferred embodiment, the paint layer and located on top of the effect layer at least partially surrounded by another layer of colorful. To this end such a surrounding layer of paint has a missing part, the contours of which is oriented outer contours of the paint layer and the effect layer. The effect of the layer and/or the paint layer and the paint layer in the preferred embodiment, is directly adjacent to each other with high precision register relative to each other. In this way the protective element creates two visually legkorastvorimyh section that, when the inclination of the protective element are clearly distinct properties. This improves the visual appearance of the Kipp effect and discrete change one information to another, accordingly one graphical image to another in the area of the paint layer and the effect of the layer.

In a preferred embodiment, the surrounding paint layer also has at least two sections, the color tones are in harmony among themselves, and which in the preferred embodiment, are characterized by the presence of similar design tools, for example, have the same thickness of the strokes that information, the playback IMEI: the led of the color layer, and/or information reproduced the effect layer.

In a preferred embodiment, design tool, the effect of the layer purposefully continue in the surrounding paint layer, resulting in the effect between the layer and the surrounding layer of colorful design there relationship. Conversely, due to this information or image, reproducible/repeatable effect layer, forms a continuation of the design visible from any angle of view of the surrounding paint layer, which improves visual perception and the distinctiveness of the playback effect-layer image man when viewed them protective element at an angle manifestations optical effect owing to a deliberate continuation of the registration of one layer to another. Around the same paint layer on the nature of its design clearly stands out located under the effect of the layer of the paint layer, i.e. on the background playing them or playing them in the image, thus improving its appearance and visual perception due to its contrast with the surrounding paint. Thus, in General, improves the visual perception of the proposed invention in binary Kipp effect, resulting in a change between images using the paint layer, with one of the second side, and the effect of the layer on the other side.

In another embodiment, the surrounding paint layer continues execution under the effect of the layer of the paint layer, resulting in the surrounding layer of paint stands out against the background image, reproduced the effect layer. In this embodiment, due to the presence of the surrounding paint layer also improves the visual appearance of binary Kipp effect.

In a preferred embodiment, at least one color tone different areas of the paint layer is a complementary color or a color from the triad, i.e. a mixture of two or three primary colors in color space. Due to this expands the range of colors that can create more contrast in its interpretation according to the present invention. The advantage of this is manifested primarily in the case when not in every hue of the color spectrum is available as a color tone of the first section the effect of the layer, for example with a limited selection of the appropriate pigmented printing inks.

Presented in this description of a discrete change from one information to another does not require to expose the protective element to any embossing. However, the protective element preferably further subjected to embossing, especially the blind stamping on rytoj effect-paint zone, resulting in the formation of relief items, inclined side surfaces which are visible from a different angle of view and thus create distinct from other areas of the visual impression. In this way possible to extend the possibilities for design of the protective element and to provide for the establishment of other optically variable effects.

In yet another preferred embodiment of the proposed invention in the protective element, at least one portion of the paint layer or effect layer contains at least one substance such as a phosphor, the absorber of infrared radiation, thermochromic paint, display, cholesteric paint and/or magnetic pigment. In this paint called in the following "cholesteric paints typically contain cholesteric liquid crystal pigments as their essential component. This makes it possible to ensure the creation of additional effects and/or integrating additional signs of authenticity in the protective element, the detection of which may require special conditions and/or use of assistive devices.

In the preferred embodiment, is similar to another substance contain one portion of the paint layer and one part of the effect layer. These plots of the paint layer and with the NGO effect layer thus complement each other to jointly playing their third information, for example up together playing their third image. In accordance with this proposed invention the protective element carries additional information that becomes visible under appropriate conditions of supervision, for example by irradiation of ultraviolet (UV) radiation in the case of phosphors.

In yet another preferred embodiment of the proposed invention in the protective element is at least one of the two sites, the paint layer is formed of two one metameric with respect to each other inks. Such one metameric colors can be choose so that both in normal lighting, for example in natural light, creating the same color impression and only when illuminated by a special light source created with different color impressions. In this way, you can get hidden, not visible under normal handling of the protective element of the protective trait.

In the above description, the protective element is assumed that the effect of the spatial layer is located above a layer of colorful, examining which therefore occurs through the effect layer. In principle, however, these layers can be placed in reverse order. For this purpose, use, for example, transparent, translucent or opaque in on the reflected light of the effect layer located on top of transmission, and preferably having a high light transmission layer of colorful. At the location of the proposed invention is a protective element on translucent primarily transparent basis, such as film element may be the location of the paint layer on the base with applied over it effect the layer and option with the location of the effect layer coated on top of him paint layer. The protective element with translucent primarily transparent, usually, for example, with its location in front of a window (hole) in the valuable document to be viewed from two sides. As materials for the manufacture of such film can be first to use such polymers as polyethylene terephthalate, polybutylene terephthalate, polyethylenterephthalat, polypropylene, polyamide, polyethylene. In addition, the film may be subjected to uniaxial or biaxial orientation stretching.

In principle, it should be noted that as the material basis for application of the protective element you can use paper of any type, especially paper from cotton. Obviously, you can also use paper containing polymeric material in the relative number of x, which can range from 0 to 100 wt.%.

In addition, as the substrate carry the I information is in principle possible, although currently not preferable to use a polymer film such as polyester film. Such film may be additionally subjected to uniaxial or biaxial orientation stretching. In the orientation film stretching it, among other things, gets sleepilerious properties that can be used as an additional protective feature.

In addition, it may also be useful to use as a base material of a multilayer material having at least one layer of paper or manageradobe material. Such multi-layer material is characterized by high strength, what is an important advantage from the point of view of durability of the base, respectively, of the recording media.

However, as the substrate material can continue to use a multi-layer, not containing paper composite material, the use of which is especially preferred in the manufacture of him first of all IDs in the form of cards and credit cards. Such materials are preferred for use primarily in some climatic zones of the Earth.

For education the effect of the layer can be used not only creating their color impression ink, but also a mixture of different colours, containing the x, if necessary, various pigments and pigments of various types. So, for example, can be mixed Iriodin pigments and in this way purposefully to adjust the desired color tone of the corresponding plot of the effect layer, the angle of the manifestations of the optical effect of the site and the range of angles manifestations them optical effect. Similarly you can also mix between different types of pigments Colorcrypt, pigments OVI and pigments STEP in order to create in this way the desired color impression. In addition, you can also mix between the pigments of all these different types, resulting in a plot of the effect of the layer will be appropriate mixture of two or more Iriodin pigments, Colorcrypt, OVI, and STEP. Such pigments equally can be mixed with other pigments. In this first preferred mixture of Iriodin pigments and silver pigments.

All materials used for the execution of these fundamentals, the paint layer and the effect of the layer may contain additives, which serve, for example, signs of authenticity.

First of all, you can use phosphors that in the wavelength range of the visible spectrum, preferably not visible and, for example, transparent and allow you to bring them within the range of wavelengths invisible region of the spectrum suitable auxiliary means, such as springs at travoltage or infrared radiation and in this case begin to emit visible or at least find AIDS fluorescent radiation. Such phosphors have depending on the desired effect to have the necessary luminescent properties. This refers primarily to the wavelengths, respectively spectra of excitation and emission, but also to the decay time of the luminescence (fluorescence or phosphorescence) after switching off the excitation radiation. When using several different phosphors they are depending on the desired effect may vary among themselves their luminescent properties. For example, in different parts of the paint layer and the effect of the layer can be used phosphorescent phosphors with different decay time fluorescent radiation.

With the achievement of the relevant benefits can be used and other protective signs, provided that they do or at least not significantly degrade the monitoring proposed in the invention of binary Kipp effect, manifested by a protective element. For applications such as protective elements are suitable, for example, absorbers of infrared radiation (with appropriately chosen, if necessary, different absorbing and/or emitting properties), thermochromic paint, one metameric colors, indicators, such as markers, holographic sequins and/or phosphors, serving as a sign of authenticity, Hollister the ical paint or soft and/or hard magnetic pigments. These various additives may also be used in combination with themselves and this can be provided on one or on different parts of the paint layer and/or effect layer. When using one metameric inks one part of the paint layer or effect layer can be subdivided into two related or unrelated to subcaste, each of which bears on the paint, which is one metameric with respect to the paint on the respectively other subcaste. When illuminated, for example, standardized achromatic white light source (D65) paint on both subacoustech create identical color impression, and otherwise acceptable lighting, such as incandescent lamp, create different color impressions.

The effect of the layer can be made shiny (glossy or matte. The effects layer can itself be performed matte or shiny, which can be used are suitable for this purpose, for example, the stitching under the influence of ultraviolet radiation binder, such as monomers or prepolymers. In another embodiment can be also applied to the effect layer, for example by printing, glossy or Matt lacquer.

In a particularly preferred embodiment, one plot of the effect layer is made of matte, and the other section is made brilliant. Thanks to better distinct the path and the visual perception of the image, reproducible effect layer, when viewed at an angle manifestations optical effect, whereas when viewed at the right angle of view of the visual impression created by both parts of the effect layer, practically do not differ. It also improves the visual perception of the proposed invention in binary Kipp effect, resulting in a change between the information reproduced colored layer, and information, reproducible effect layer. In that case, when you have to create this effect on some areas use shiny or Matt varnish, in the preferred embodiment, is printed on top of the effect-layer protective element with exact registration. As an example of the formulation shiny varnish (water-based), which can be applied by flexographic printing method, can be called composition containing a dispersion of polyurethane in an amount of about 10 to 20 wt.%, the non in the amount of about 1 wt.%, the wax in an amount of about 1 wt.% and dispersion of polyacrylate in an amount of from about 78 to 88 wt.%. As an example of the formulation of Matt varnish (water-based), which can be applied by flexographic printing method, can be called composition containing a dispersion of polyurethane in an amount of about 10 to 20 wt.%, the non in the number primer the 1 wt.%, the wax in an amount of about 1 wt.%, matting agent on the basis of silicic acid in an amount of about 8 wt.%, water in an amount of about 2 wt.% and dispersion of polyacrylate in an amount of from about 68 to 78 wt.%.

Proposed in the invention, the protective characteristic is used primarily for the protection of various kinds of goods, valuable objects, media, and other objects, primarily to protect them against forgery.

Different areas of effect-layer principle can be applied to all common printing methods such as silk screen, flexographic, gravure and metallographic printing. Preferably, however, to use the screen or flexographic printing. A method of flexographic printing is the most preferred method of printing primarily on the basics of paper as their main component, because it allows to process printed material with high speed and when the printing effect paints allows you to achieve basically the same quality printing as a method of screen printing. For printing on the basics with a polymer film as their main component (susceptible to the paint layer or without it) is most preferred first method of gravure printing.

Different areas of the paint layer is also in principle possible nano is resolved almost all common printing methods.

Preferably, however, use the method of offset printing, while the paint layer can be applied by offset printing method, moisture forms, by dry offset printing and method of typeofdata, which is the most preferred.

Another surrounding the paint layer can also be applied to all common methods of printing. Preferably, however, to use for this purpose the method of typeofdata when printing the so-called method of "Super Simultan". Used for printing by the method of "Super Simultan" printing machines allow high-precision register to print all printing inks on the one hand, and all of the printing inks with the front and back sides of the printed base/printed media.

In a preferred embodiment, the method of typeofdata for applying the paint layer and flexographic printing method for applying the effect layer is used during a single printing process, which in this case includes, for example, four separate printing stage (two stage printing for applying the paint layer, respectively, the effect-layer). In addition, in combination with these stages of printing, you can also use the method of typeofdata, which in the printing machine for printing by the method of "Super Simultan" print another surrounding paint layer, in accordance with, for example, the basement area of the paint layer, the effect of the layer and the surrounding ink layer is printed in a single printing process in six stages.

In a preferred embodiment, the basis, for example, is protected from a fake (emission) paper as a semi banknotes, first seal another surrounding paint, then the paint layer and then the effect of the layer.

Other embodiments of the invention and its advantages are discussed below in more detail based on examples with reference to the accompanying description of the drawings on which is shown:

in Fig.5 is executed by one of the following layered structure proposed in the invention, the protection element

in Fig.6 is executed by one of the following paint layer with one metameric inks

in Fig.7 is an example of an image reproduced paint layer.

In Fig.1 as the carrier info is information showing a banknote. It has a paint layer 1 and located on top of it and combined with it the effect of layer 2, and another of the colored layer 3 (see Fig.2). In addition, the bill caused its value as the number "50".

In Fig.2 schematic cross section showing the protective element. On the basis of 4 applied paint layer 1 consisting of several closely adjacent to each other opaque portions 1a, 1b. On top of the paint layer 1 is the effect of layer 2 having a first section 2A, and the second, closely adjacent section 2b. Both layers - paint layer 1 and the effect of layer 2 plays according to some information in the form of (graphic) images (see Fig.3A and 3b), however, the two images differ. When viewed under direct vision angle A (Fig.3A, the angle is 0° relative to the perpendicular to the surface of the protective element) both plots 2A, 2b effect layer 2 transparent so that visible information, reproduced below located paint layer 1, whereas the information reproducible effect layer 2, are not visually distinguishable. Sections 1A and 1b of the paint layer 1 are in harmony with each other on the color. When viewed at an angle manifestations optical effect (Fig.3b), is equal to, for example, 45°, each of the two sections 2A, 2b effect layer 2 reveals the presence of a color tone, while the color tone of the first plot is SDA 2A creates for the human eye for more contrast with the color tones of the sections 1a, 1b of the paint layer 1, and the color tone of the second area 2b is in harmony with the color tones of the sections 1A, 1b of the paint layer 1.

In other words, when viewed protective element at right angle, i.e., when viewed along a line perpendicular to the surface of the protective element, due to the high under this perspective, the transparency effect layer 2 predominant color image derived from underneath him paint layer 1. Thus in the ideal case, when viewed protective element at right angle you can only see the image, reproducible paint layer 1 and formed by two colors, in harmony with each other, but nevertheless distinguishable from one another by the human eye. In this case, the protective element can be seen when illuminated with diffuse light.

When examining the protective element under "angle manifestations optical effect (also called the "Bragg angle of reflection or a glide angle) due to the translucent mirror Shine effect-layer 2, respectively, both used in areas 2A and 2b the effect of colors of the color image derived from the underlying paint layer 1, in the ideal case completely disappears and therefore the human eye in the ideal case only accepts throw upstream effect layer 2. the related words, the dulling effect/brilliance dominates so that people visually perceives and analyzes the information, currently playing in the manifestation of this effect matte/gloss. In this case, the lighting in the ideal case using a directional light and angles and the fall of the illuminating light is symmetrical with respect to the perpendicular to the surface of the protective element. The angles of incidence of the illuminating light and the view are, for example, 30°, 45°, 60° or 75° relative to the perpendicular to the surface of the protective element.

Combined between the paint layer 1 and the effect of layer 2 surrounded by another closely adjacent colored layer 3. This colorful layer 3, in turn, consists of two parts 3A and 3b, according to shown in Fig.2 view in transverse section to the effect layer 2 and a paint layer 1 is directly adjacent only area 3A. Cross section of another plane to effect layer 2 and a paint layer 1 adjacent if, for example, section 3b.

When the tilt (swing) is schematically shown in Fig.2 protective trait in one and the other side with a periodic change of the angle between the direct angle of view and angle manifestations optical effect In alternately become visible information, reproducible paint layer 1, and information, reproducible effect layer 2, while DL is achieving binary, full change one information to another, accordingly one graphical image to another for the formation of various sections 1A, 1b, 2A, 2b, 3A, 3b of the paint layer 1, the effect of the layer 2 and the surrounding paint layer 3, it is necessary to choose acceptable acceptable paint colors.

In the first example embodiment of the invention for formation of sites of different layers use the following colors:

the surrounding paint layer 3: paint P 214 (red) and paint P 326 (blue-green);

- the paint layer 1: paint P 658 (blue) and paint P 529 (purple);

- part 2A: paint Iriodin copper color (more contrast);

- part 2b: paint Colorcrypt purple-green (matching color).

Identify different printing inks (for example, P 214) refer to PANTONE color model. For designation of colours, according to their colors, you can use other color systems, such as MKS and/or RAL.

The exact correlation of these colors with different sections of paint layers 1 and 3 are insignificant. Hue in areas 1A, 1b, and 2b in harmony among themselves, while the color tone on the plot 2A creates more contrast with the color tones of the sections 1A, 1b, and 2b.

In the first version of this example embodiment of the invention for the formation of area 2A using a paint Colorcrypt Golden-green is the main color (for more contrast), and education section 2b use paint Iriodin purple color (matching color). In the second option considered the first example embodiment of the invention in section 2A use paint Iriodin copper color (more contrast), and at site 2b use paint STEP copper-green (matching color). STEP-paint is usually made on the basis of cholesteric liquid crystal pigments and are color Kipp effect. Paint STEP copper-green" has a specified hue. In yet another variant of the first embodiment of the invention in section 2A also there is a similar STEP-paint with acceptable additional hue.

Proposed in the invention of the color characteristic in the first variant of the first embodiment of the invention quantitatively evaluated in the color space Lab, using multiple-angle colorimeter (X-Rite MA 98 company X-Rite). When measuring in a position at right angle view" protective element light at an angle of incidence of the illuminating light 45° relative to the perpendicular to the surface of the protective element, and see along the perpendicular to its surface. When measuring the position angle of the optical manifestations of the effect of the protective element also light at an angle of incidence of the illuminating light 45° relative to perpendicular the and to the surface of the protective element, and see an angle of 30° relative to the perpendicular to its surface and thus at an angle measurement, which is 15° deviates from the Bragg angle of reflection.

Corresponding to the invention, subjectively perceived color difference between two colors is determined in a known way on the basis of the Euclidean distance between two points in the color space Lab. In the table below, the parameters F1 and F2 and E1 and E2 refer to the colors of inks used in each of the areas of the paint layer and the effect layer. In this case, in particular:

F1: paint P 658 (blue)F2: paint P 529 (purple)

As shown in the above table, the color impression in the measurement position at right angle view" only slightly depends on the color of a specific paint E1 or E2 effect layer. Conversely, the color tone measured in the color space Lab in position angle manifestations optical effect, largely depends on the paint color effect layer.

In the ideal case, as mentioned above, when measuring the position angle of the optical manifestations of the effect have not been able to install any dependencies of the measured color tone from downstream of the paint layer 1 (F1 and F2), whereas in the measurement position at right angle view" it should not have any dependence on color effect layer 2. The existence however, this dependency can be explained primarily by the fact that the measurement of the position angle of the optical manifestations of the effect was carried out as described above, not under the so-called Bragg angle of reflection, and under different 15° angle. When selecting the optimum measurement conditions, we should expect the best results of measurement of the colour tones. In addition, various color impressions can optimize the ed, optimizing the degree of coverage paints E1 and E2 in areas 2A and 2b the effect of the layer 2. In addition, further optimization of the measured color space, Lab color tones can be achieved by improving the transparency effect layer 2 and the optimization of the orientation of the effect pigments in the effect layer 2.

In the second example embodiment of the invention uses the following colors:

the surrounding paint layer 3: paint P 528 (purple) and paint P 659 (blue);

- the paint layer 1: paint P 611 (yellow) and paint P 466 (ochre);

In the composition of the flexographic ink used to apply the effect layer in examples 1-4, it should be noted that it is the water-based paint containing as a solid phase polyacrylate and polyurethane (in a relative amount of about 40 wt.%). Pigments are added to achieve a concentration equal to about 20 wt.%. As diluent use water, and the solvent is 1-methoxypropan-2-ol (together they accounted for about 40 wt.%). When using paint this composition is achieved a particularly high gloss. Usually in a paint composition additionally use several auxiliary substances (additives), which accounted for less than 1 wt.% (for example, wetting, pH neutralizers, thickeners, antispyware). High gloss achieved when using these paints to create a protective element, in General, also stable compared with other colorful plots valuable document such as a banknote, which has a positive impact on the reliability of the verification of the protection element and thus on the effectiveness of protection against forgery.

Below example shows the composition of the printing ink, suitable for application of the paint layer, respectively, of the surrounding paint layer:

organic colored pigments
about 1-20%
modified linseed oil alkyd resinabout 0-20%
binder on the basis of modified hydrocarbons of rosins and mineral oil/flax oilabout 20-98%
wax, for example, micronized polyethylene waxabout 0-2%
solids-based octoate cobalt/manganese approximately 1-2% mineral oilapproximately 0-4%

In addition, the composition of the printing inks may also include other excipients and solvents, especially water. The effect layer is applied using a special rasterized roller, made by ART-tech. In the manufacture of rastor roller ART-technology (from the English. "Anilox Reverse Technology", "technology anilox reverse printing"), developed by Praxair, on the surface rasterimage roller engraving by special technology raster form a special geometry, making possible the processing of relatively large pigment size up to about 40 microns.

In Fig.3A shows a graphical image as the information is AI, reproducible paint layer 1. In Fig.3b shows a graphic image as information, reproducible effect layer 2. Throw paint layer 1 is a stylized image of the crown and thereby easily picture with a substantial meaning for the person. The same image, reproducible effect layer 2, represents the image of the number "50" around which in addition is distracting ("nuisance") background structure in the form of strips. Thus in each of the graphic images reproduced by both layers, using two colours, namely: hue sections 1A and 1b of the paint layer 1, and color tone areas 2A and 2b the effect of the layer 2. It is obvious that instead of the shown in Fig.3A, the image of the crown you can use other images, such as (stylized) depiction of the animal (Swan, Rhino and so on), (stylized) depiction of the head of the animal (lion, bear and so on), (stylized) depiction of plants (palm trees, flower and so on), the image of the known symbol (the Eiffel tower, Brandenburg gate, and so on) or other similar image. In addition to graphics played on the effect layer 2, not significantly, which both sections 2A, 2b in Fig.3b is printed paint updat the additional colors i.e., a binary change from one information to another takes place, obviously, in the case when the effect-paint optional color tone covers the area marked in Fig.3b position 2b. Accordingly, the area marked in Fig.3b position 2A, would in this case matching the color tone. Similar to the embodiment of the effect layer 2 shown in Fig.3V. Reproducible effect layer 2 image in the form of the number "50" and distracting background patterns formed parts 2A (for more contrast) and 2b (blending color), which is shown in Fig.3b embodiment are reversed compared to the areas 2A, 2b shown in Fig.3b version. It is obvious that the relevant notes relate to the correlation of colour with separate sections 1A and 1b of the paint layer 1.

In one of the embodiments shown in Fig.2 the layered structure effect layer 2 applied directly to the base 4, and the paint layer 1 deposited on top of the effect layer 2. Said illustrated in Fig.5. In the first modification of this variant, the base 4 is transparent or at least translucent and therefore inspection of the protective trait is through it that are marked by arrows And' and'. In the second modification of this option for applying the effect of the layer 2 on each of the component sections 2A and 2b translucent or opaque effect paint while the application is located in this case on top of the paint layer 1 using printing inks with extremely high light transmission. In this modification, the protective sign of consider, as before, directly from its location, and the base 4 can therefore be opaque.

In yet another embodiment presented in the drawings of embodiments of the invention, the parts 1A and 1b of the paint layer 1 and/or sections 2A and 2b, the effect of the layer 2 not printed close to each other, and with a space from each other. Thanks for creating color impressions can be used, for example, and the color tone of the underlying fundamentals 4.

In addition, in Fig.4 shows another variant, in which the effect layer, consisting of sections 2A (for more contrast) and 2b (blending color), is in the form of another section 20A (for more contrast) in the area surrounding the paint layer 3 (media 4), preferably with accurate wiring to this colorful layer 3. In the form shown in the drawing example, a separate line on the plot 20A continue in the area surrounding the paint layer 3, which is also applied in the form of a pattern of lines. It is obvious that the line 20A may, for example, be placed with exact register with the surrounding paint layer. In principle possible a variety of sh which we location the effect of the layer 2 and the outside of the paint layer 3 in order to strengthen binary Kipp effect in his perceptions. For example, it is also possible in which the image is reproducible effect layer 2, is a semantic relationship with the surrounding paint layer 3, i.e., for example, the image reproducible effect layer, represents the image of the sun, the rays of which at least partially formed surrounding paint layer. In any case, and is shown in Fig.4 embodiment, amplified binary Kipp effect proposed in the invention is a protective element in his perceptions, and thereby increases the degree of protection against forgery.

In the fifth example embodiment of the invention at least one of the parts of the paint layer 1 and/or effect layer 2 exhibits fluorescent properties. It may be fluorescence or phosphorescence, and in the latter case is chosen acceptable decay time of the luminescence. In addition, selected suitable characteristics of emission of the luminescence of the phosphor or phosphors and his or their absorption characteristics, thus achieving the desired effect.

In the first variant of the fifth embodiment of the invention only one of the two parts of the paint layer 1 contains a fluorescent phosphor. Upon excitation of such a phosphor image appears, reproducible layer of colorful and becoming in this case, visible in the e depending on the angle of view. In this embodiment, excitation light which excites the phosphor, must not be weakened upstream effect layer 2. Since the phosphors are usually excited by ultraviolet (UV) radiation, the above effect is a layer 2 should therefore not contain any absorbers of UV radiation. Such absorbers of UV radiation on the basis of titanium dioxide (TiO2contain, for example, pigment Iriodin representing rutile light yellow or light blue or pigment Colorcrypt Golden manufactured by Merck. Among the effect pigments suitable for the formation of the effect layer 2 includes, for example, liquid crystal pigments or pigment Iriodin 4504 Lava red (red) and pigment Colorstream F10 Autumn Mystery, also manufactured by Merck.

In the second variant of the fifth embodiment of the invention both plots of the paint layer 1 contain phosphors. They differ in their wavelengths, respectively, their spectra of radiation and the emission of fluorescent radiation create different color impressions. The first plot fluorescent, for example, in the red wavelength range and the second area is in the blue wavelength range. Thus in the second embodiment, as in the above-described first embodiment, improved throw paint layer 1, and for education the Oia upstream effect of the layer 2 is necessary to choose a suitable effect pigments, which do not absorb the radiation of the excitation of the phosphors of the paint layer 1.

In the first and second embodiments, the fifth embodiment of the invention the effect of the layer 2 does not contain phosphors.

In the third embodiment, the fifth embodiment of the invention only one of the two plots of the effects of layer 2 contains a fluorescent phosphor. Thus, the excitation of such a phosphor image appears, reproducible effect layer 2 and becomes visible when the emission of fluorescent radiation not only at an angle manifestations optical effect, but under all the angles. The phosphor applied luminestra paint as such in the ideal case is completely transparent and at least in the visible region of the spectrum does not have its own color. Thus, such a phosphor is not visually noticeable, but visually perceptible effect layer 2 is not changed as long as the phosphor will not luminesce. In the same case, when the phosphor, respectively, used fluorescent paint is not fully transparent transparent, by proper choice of components, in another part of the effect layer 2 is necessary to ensure the creation of a fairly similar visual impressions both parts of the effect layer 2 outside corner manifestations optical effect so that these areas nevoso is but can tell one from the other. While it is preferable to use as possible necrosi the phosphor order to reduce to the lowest possible deterioration of the visual distinctness of image, reproduced below located paint layer 1. The advantage of this variant of the fifth embodiment of the invention is that the effect pigments of the effects of the layer 2 can be absorbing UV radiation and thereby impose fewer restrictions on their choices than in the first and second embodiments, the fifth embodiment of the invention.

In the fourth embodiment, the fifth embodiment of the invention both sections 2A and 2b, the effect of the layer 2 provided by the phosphors. They also differ in their wavelengths, respectively, their radiation spectra. While one site may fluoresce in the red wavelength range, and another part of the effect layer 2 fluorescent in the blue wavelength range. In the absence of both excitation phosphor, respectively, both y paint in the ideal case, as mentioned above, do not have their own color and therefore not visually noticeable, which saved the visually perceptible image, reproduced below located paint layer 1. If some of the visual distinctiveness of the phosphors on the effect layer and in the absence of vosburg the deposits necessary to take measures at least to to both plots the effect of the layer was created as homogeneous visual impression out of the corner manifestations optical effect and possessed the lowest possible opacity.

In the third and fourth embodiments, the fifth embodiment of the invention the paint layer 1 does not contain phosphors.

In the fifth embodiment, the fifth embodiment of the invention one part of the paint layer 1 and one part the effect of the layer 2 containing the phosphor. Both have the same color phosphor emitted by their fluorescent emission, and in the simplest case, both sections can provide the same phosphor. Thus, the excitation of the fluorescent phosphor, an additional third information, which under certain conditions can be a graphic image, and which is composed of both fluorescent areas.

In one modification of the fifth variant of the two plots have different wavelengths of radiation, radiation spectra, respectively, and create different color impressions.

In other modifications of the fifth variant of the fifth embodiment of the invention both sections of the paint layer 1 and/or effect layer 2 can be provided by the phosphors, fluorescent in different wavelength ranges. In these embodiments, the ri of certain conditions, it is necessary to take into account the above mentioned limitations regarding the choice of components, the effect of the layer.

In the sixth embodiment, the fifth embodiment of the invention in one area of the paint layer 1 provides a fluorescent phosphor, and at another part of the paint layer 1 is provided phosphorescent phosphor. The effect of layer 2 does not contain phosphors. Both colorful phosphor layer 1 is selected so that when the excitement they create the same color impression and above all have the same emission color with the same intensity, and therefore, when the excitation of the paint layer 1 looks like a solid surface. After cessation of excitation during the decay time of the luminescence emitted by the phosphorescent phosphor, remains visible, a corresponding portion of the paint layer. In other words, during the decay time of the luminescence emitted by the phosphorescent phosphor, it is possible to see you throw paint layer 1. This is one of the parts of the paint layer 1, for example, fluorescent yellow, and another part of the paint layer 1 absorbent for use in yellow. In this case, the upstream effect of the layer 2 in the ideal case also does not contain substances which absorb radiation from the excitation of the phosphors of the paint layer 1.

The advantage of phosphorescent phosphors is their particularly high suitability for automatic about what Eugenia, while primarily paint Iriodin due to the inherent properties to change its color, i.e., because of the symptoms they Kipp effect, where there is a change between in the ideal case of full transparency when viewed at the right angle of view and create a shining pearl color impression when viewed at an angle manifestations optical effect, less suitable for automatic detection.

In the seventh embodiment, the fifth example of the invention, the fluorescent and phosphorescent phosphors provided on both plots the effect of the layer 2. The paint layer 1 does not contain phosphors. In this seventh embodiment, it is possible to achieve basically the same effect as in the above-described sixth embodiment, and in this case there are fewer restrictions on the choice of effect pigments for the education effect-layer 2 (as already described above).

In the eighth embodiment, the fifth embodiment of the invention in one area of the paint layer 1 provides a fluorescent phosphor, and part of the effect layer 2 is provided a phosphorescent phosphor. Each of the other areas of the paint layer 1 and the effect of the layer 2 does not contain phosphors. The fluorescence intensity of the fluorescent phosphor in the paint layer 1 is clearly higher than the intensity of the phosphorescence of the phosphor in the effect layer 2. Those with the most at excitation dominates the emission of the fluorescent area of the paint layer 1. Therefore, when the excitation becomes visible image reproduced paint layer 1. After cessation of excitation during the decay time of the phosphorescence in the effect layer 2 can be seen played them the image. Accordingly, when the exciter is a change of image, the playback paint layer 1, on the image, reproducible effect layer 2.

In another embodiment, emitting radiation of high intensity fluorescent phosphor can also be provided on the effect layer 2, and emitting radiation of lower intensity phosphorescent phosphor is in the paint layer 1.

In addition, in another embodiment, instead of one fluorescent and one phosphorescent phosphors can also include two phosphorescent phosphor, which have clearly distinguished between a decay time of their luminescence. In accordance with this after cessation of excitation in the first period of time, you can see the image, played the layer that contains more intensively emitting phosphorescent phosphor with a smaller decay time of its luminescence, and in the subsequent period of time you will be able to see you throw the layer containing the phosphorescent phosphor with a great time is February attenuation of its luminescence, which in this case will be a change between images, reproducible paint layer 1 and the effect of layer 2.

In the ninth embodiment, the fifth embodiment of the invention in one area of the paint layer 1 provided the first phosphor, and part of the effect layer 2 has a second phosphor. Both phosphor differ in their spectra excitation so that it is possible selective excitation of each of them. For example, one of the phosphors can initiate short-wave optical radiation, and the second phosphor - wavelength optical radiation. However, both the spectrum of the excitation may be in the ultraviolet region of the spectrum. Thus, depending on the selected excitation radiation can selectively make visible the throw paint layer 1, or the image, reproducible effect layer 2.

It is obvious that different, the above variants of the fifth embodiment, of the invention can reasonably be combined with each other in order to create the desired effect.

In the sixth example of the invention, the at least one portion of the paint layer 1 or effect layer 2 contains absorbing and radiating in the infrared region of the spectrum matter (below called poglotitelem-radiation). Such an absorber of infrared radiation in the ideal case are not visually discernible in the visible region of the spectrum.

In the first variant of the sixth embodiment of the invention one part of the paint layer 1 contains such an absorber of infrared radiation. Another part of the paint layer, and the effect of layer 2 does not contain absorbers of infrared radiation. Accordingly, by proper excitation of infrared radiation by using a thermal imaging camera (for example, thermal imaging camera and an infrared transmitter) to recognize and treat you throw paint layer 1. In another embodiment, the absorber of infrared radiation can also be provided on only one plot effect layer 2 and to do so by a recognizable image, reproducible effect layer 2.

In the selection of substances as an absorber of infrared radiation within the meaning of the fair, the same explanations that relate to the choice of phosphors in the fifth embodiment, of the invention and in accordance with which the optical appearance of the paint layer 1 and the effect of the layer 2 should not deteriorate at all, or may deteriorate only slightly.

In the second variant of the sixth embodiment of the invention in one area of the paint layer 1 provided the first absorber of infrared radiation, and in one section the effect of the layer 2 is provided uterological infrared radiation. On each of the other areas of the paint layer 1 and the effect of the layer 2 is not provided absorbers of infrared radiation. Both absorber of infrared radiation differ in the wavelength of their excitement. In accordance with this it is possible by proper choice of wavelength excitation to provide selective detection image, the playback paint layer 1, or image, reproduced the effect layer 2, a thermal imaging camera. For selective excitation is possible to use the barrier IR-filter, tuned to a specific wavelength of excitation induced absorber of infrared radiation. Alternatively, you can also use two absorber of infrared radiation with different wavelengths, which allows you to use a thermal imaging camera and using, for example, the barrier IR-filter, which is tuned to a specific wavelength selectively detected image, to selectively render visible to throw paint layer 1 or the effect of layer 2.

In addition, with respect to the sixth embodiment of the invention in the sense you can also use the above in the description of the fifth embodiment of the invention by varying the properties of the paint layer and the effect of the layer.

In the seventh embodiment of the invention in colorful with the OU 1 and/or effect layer 2 provided thermochromic (heat sensitive) paint, which in a given temperature interval become transparent invisible, but outside of this temperature range have some of its own color.

In the first variant of the seventh embodiment of the invention one of the two sites, the paint layer consists of a thermochromic paint. Another part of the paint layer and the effect of layer 2 does not contain thermochromic paint.

Thus, in a given temperature range characteristic of thermochromic paint, one part of the paint layer 1 becomes transparent, and the color impression of this area is defined below.

In the second variant of the seventh embodiment of the invention each of the two sections of the paint layer 1 formed his thermochromic paint, set the temperature intervals in which both thermochromic ink becomes transparent, at least mutually overlap, and in the ideal case are the same. Thus, when setting the temperature to a value lying within a mutual overlapping temperature intervals, the entire paint layer 1 becomes transparent, and therefore, in this temperature range outside corner of the manifestations of the optical effect of the upstream effect is layer 2 only below the base 4 creates a homogeneous color impression. When the regardless of the temperature due to the presence of a homogeneous background also improves the visual appearance of information, reproducible effect layer 2 when it is viewed at an angle manifestations them optical effect.

When performing the paint layer 1 thermochromic inks, as is the case in the first and second embodiments, the seventh embodiment of the invention, such thermochromic paint should ideally have its own color, brightness, high enough to distinguish between images, the playback paint layer 1.

In the third embodiment, the seventh embodiment of the invention, one or both of the plot effect layer 2 optionally have one thermochromic paint or different thermochromic paint. In this case, the above-described binary Kipp effect, i.e., occurring when the angle of view change between the image using the paint layer 1, and an image reproducible effect layer 2, can be observed only when setting the temperature value at which thermochromic paint effect-layer 2 become transparent. In other words, the effect is shown the effect of layer 2 remains hidden at temperatures outside the specified temperature range. If you have the same thermochromic paint on both plots the effect of the layer 2 of the protective component is outside of the specified temperature range as a homogeneous, solid surface. When using different termor is mnih paints on both parts of the effect layer 2 played them the picture you can see outside of the specified temperature range, in which thermochromic ink becomes transparent, and from all angles of view.

In the fourth embodiment, the seventh embodiment of the invention one part of the paint layer 1 and one part the effect of the layer 2 is supplied with thermochromic inks. In this case, binary Kipp effect becomes noticeable when setting the temperature to the desired value. In other words, a corresponding portion of the paint layer 1 transparent in the set to present it thermochromic paint temperature range and not transparent at temperatures outside of this temperature range, while the corresponding plot of the effect of layer 2 at a temperature outside the temperature range specified for thermochromic paint effect-layer 2, it becomes visible in its own color, and at a temperature within a specified temperature range of transparent and therefore allows you to see depending on the angle of view of the effect created by the effect of layer 2.

In the eighth embodiment of the present invention one part of the paint layer consists of two subcostal 1A and 1ab, as shown in Fig.6. Both of these subcaste together form a plot 1A, known from other examples of embodiment of the invention. Both subcaste 1A and 1ab formed one metameric inks. They are in the coverage of the first radiation source, e.g. the, standardized achromatic white light source D65, create the same color impression and therefore are visually perceived as a uniform area. While covering the second radiation source, such as incandescent lamp, both subcaste 1A and 1ab create different color impressions. This feature can be used as a sign of authenticity, which cannot be detected in a simple way.

In the ninth example embodiment of the invention only one of the two plots is the effect of the layer 2 or both its plot has a light, the mere existence of which may, for example, serve to confirm the authenticity.

Such indicators or indicator pigments are, for example, markers, holographic sequins or phosphors.

In the tenth embodiment of the invention at least one of the parts of the paint layer 1 or effect layer 2 contains cholesteric paint. Such at least one area becomes visible when it is viewed through a suitable for this purpose, a polarizing filter, under certain conditions, depending on the orientation of the latter.

In the first variant of the tenth embodiment of the invention both plots of the paint layer 1 composed of a cholesteric paints that create different is between a polarization effects. The effect of layer 2 does not contain cholesteric paint. When viewed with the naked eye this difference in polarization of the emitted colored layer 1 of light it is impossible to see. It can visually be detected only when viewed through suitable for this purpose polarizing filter.

In the second variant of the tenth embodiment of the invention each of the two sites, the effect of layer 2 contains cholesteric paint. The basis of both paints are cholesteric liquid crystal pigments, with the helical structure of cholesteric phases both cholesteric different colors. When examining the effect of layer 2 through suitable for this purpose, a polarizing filter or by using a so-called reader STEP-colors (STEP-Watcher") plots the effect of the layer 2 become visible or invisible.

In the eleventh embodiment of the invention in effect layer 2 is provided by magnetic pigments.

In the first variant of the eleventh embodiment of the invention only one of the two plots is the effect of the layer 2 is provided allowing the automatic detection (machine-readable) magnetic pigment.

In the second variant of the eleventh embodiment of the invention both plots the effect of the layer 2 has the same magnetic pigment. Thereby correspondingly square effect-SL is I 2 is formed on the whole, large, machine-readable surface.

In the third embodiment, the eleventh embodiment of the invention one area effect layer 2 has a magnetic pigment, whereas another part of the effect layer 2 has a hard magnetic pigment. The result is a machine-readable code, respectively, a machine-readable pattern.

Magnetic pigments generally have a slightly opaque own color, i.e., have their own color. So that when viewed protective element outside corner manifestations optical effect layer 2 to ensure the creation of the underlying paint layer 1 color impression which is not affected by upstream effect layer 2, on both sites provide the same own color. Compliance with such conditions it is necessary above all in the case when, as in the first embodiment to the eleventh embodiment of the invention, only one plot effect layer 2 provide a magnetic pigments or when, as in the third embodiment, the eleventh embodiment of the invention, the both parts of the effect layer 2 provided by different magnetic pigments. One of the possibilities to give even own colour is that on one of the sites additionally provide usable for this purpose organic pigments. the other option for this purpose can also be used TiO 2-pigments.

As mentioned above, at least one of the two sites, the effect of the layer 2 may be a mixture of exhibiting optically variable effect pigment and, for example, pigment Iriodin silver. Such a mixture may have the composition specified, for example, is higher for the effect of the layer in examples 1-4 of the invention.

It is shown in Fig.3A, the image is passed to the paint layer 1 represents only one of many possible images that you can use to play them paint layer 1 and the effect of layer 2. In Fig.7 as another example, the playback paint layer 1 images, which should preferably be used in combination with the shown in Fig.3b is an image reproducible effect layer 2, shows the star. Accordingly, all of the above in relation shown in Fig.3A image effects and advantages are achieved when using the paint layer 1, the playback shown in Fig.7 image.
