The invention relates to a protected document that contains translucent carrier substrate, in particular made of paper and/or plastic and at least one deposited on the carrier substrate or embedded in the carrier substrate protective element, which when viewed, at least from the first side of the protected document in transmitted light shows at least one first image and simulates the presence of at least one first watermark in the carrier substrate, with the protected document, at least in some areas has at least one simulating at least one first watermark layer, which locally changes the visually perceived translucent carrier substrate.

Such protected documents known from WO 99/13157 A1. Here as a protective element on securities protective film is applied or repaired it. The protective film consists of a translucent film and a deposited metal coating, which has not containing metal zones, which clearly recognized, particularly in transmitted light. The metallic coating is divided into individual dots that create a grayscale image. If the protective film sealed between two layers of protective paper, then using a metal coating dimitromanolaki watermark in protective paper, which can be recognized in transmitted light.

Conventional watermark is created in the paper due to the fact that the thickness of the paper during its manufacture locally changed, so that the paper there are differences in light transmission. In transmitted light the observer on both sides of the paper sees a continuous grey-scale image, the so-called watermark.

Imitation watermark using protective element has the advantage that it is possible to avoid complex manufacturing process required to create a conventional watermark on paper substrates. In addition, simulated watermark, you can provide a simple way also translucent plastic substrate watermark effect. You just need to close up or cause to be created regardless of the translucent carrier substrate protected document protective element in or on the translucent carrier substrate made of paper, plastic or Teslin®, or laminates of these materials. However, depending on the implementation of the protection element can simulate different watermarks in the same carrier substrate.

However, it was found that the simulation of the watermark using separate protective elements on the protected document can also be rigged with an acceptable and cost. For this purpose, for example, between layers of paper have printed text or paste the masking layer to simulate a desired grayscale image.

Therefore, the object of the invention is the creation of a secure document, which has a particularly hard-to-imitate, simulated using protective element watermark effect.

The problem is solved for the protected document containing translucent carrier substrate and at least one deposited on the carrier substrate or embedded in the carrier substrate protective element, which when viewed, at least from the first side of the protected document in transmitted light shows at least one first image and simulates the presence of at least one first watermark in the carrier substrate, with the protected document, at least in some areas has at least one simulating at least one first watermark layer the fact that at least one deposited on the carrier substrate or embedded in the carrier substrate protective element enables visual recognition

a) in the incident light different from the first image to the second image and/or

b) in transmitted light when viewed from opposite the first side, a second side different from the first image is the position of the third image, and/or

(C) in transmitted light when viewed from opposite the first side, second side, depending on the viewing angle, at least one is different from the first image to the fourth image.

The lighting is normally provided with daylight or artificial lighting. However, these and other optical effects can be observed when additional ultraviolet or infrared radiation, if at least one simulating the first watermark layer contains one or more substances (such as, for example, fluorescent, thermochromic, photochromic substance or the like)that can be aroused with such exposure.

The execution of the protected document in accordance with the invention makes it along with the watermark effect more interesting and unexpected effects in direct connection with a simulated watermark.

Under normal embedded in the carrier substrate, simulating the watermark protective elements, the observer sees in the transmitted light from each side of the protected document, the same image watermark, asymmetric motifs only in mirror image. If the security element is applied to one side of the carrier substrate, the observer usually sees directly that the layer or layers which are held in the present light affect the light transmission of the carrier substrate. Thus the observer expects that, at least, form the opaque layer corresponds to what he perceives on the other hand as a watermark, possibly in the mirror. However, when examining the protected document according to the invention, the observer receives an unexpected optical impression, as usual effects of the watermark in this form do not appear or appear only in part.

If the protected document is viewed in transmitted light, we mean the observation by the human eye under normal conditions, when this light falls on a protected document on the rear side, i.e. opposite to the observer side of the protected document.

Preferably, when in the case (a) simulating at least one first watermark layer has zones with different light transmission.

In this case, preferably, when in the case (a), the protective element is located on the second side of the protected document or embedded in the translucent carrier substrate, the protective element is in a plane parallel to the first side and the second side, and the area of the carrier substrate, which is located on the second side between simulating at least one watermark layer and the observer, is made at least partially hollow, while visible from the second side of the zone and airwasher first watermark layer in the incident light are perceived visually as a solid, opaque zones, but at least visible areas simulating the first watermark layer are passing light of different light transmission. Thus, the observer recognizes the protected document in the case (a) as usual when viewed first hand in the passing light of the first watermark. On the other side, the observer sees in the incident light applied on the carrier substrate protective element and at least one simulating the first watermark layer, the form of which, however, against expectations do not match the shape of the first watermark. However, in transmitted light with the second hand again visible first watermark may in the mirror. This effect is achieved in that at least one simulating at least one first watermark layer is made with zones of different light transmittance, which can be visually distinguished from each other in transmitted light.

When paper or plastic (polymer) of the carrier substrate recent case in which the protective element is in a plane parallel to the first side and the second side of the protected document, and the area of the carrier substrate, which is located on the second side between the at least one opaque layer and the observer, is made with a groove, it is possible to realize the fact that the carrier substrate is made, for me the greater extent, of two layers, and at least one protective element is located between these layers. Before connecting layers, one of them provided with a window opening and a window opening positioned over the protective element so that the incident light is visible at least one opaque layer.

Under the window opening means, as well as in the rest of the text, not only the opening but also transparent or translucent area, for example, of transparent glass, plastic.

As an alternative solution, a window opening can be performed in both layers, and at least one protective element is combined with both window openings. Then the protective element coated on the first side of the at least one translucent color layer, so simulating at least one watermark layer can be recognized only from the second side.

In General, at least one translucent colour layer can be, however, already part of a protected document, so there is no need for its application after the embedding of the protective element in the carrier substrate. In addition, translucent color layer can be formed translucent layer of glue, which is used for sealing a protective element between the layers of the carrier substrate to which kleivane with one layer. Optical concealing the presence of window openings may be preferable to integrate the translucent colored layers in the protective element in combination with an additional application of translucent colored layer after sealing protective element or the application of translucent layers of glue for sealing.

In addition, preferably, when in the case (a), at least one simulating the watermark layer when viewed in the incident visible light having a different value of the surface than is recognized in transmitted light.

In addition, preferably, when in the case (a) simulating the first watermark layer deposited on the second side of the protected document and is covered in some areas, at least one, located on the second side of the translucent colored layer, or embedded in the translucent carrier substrate so that the protective element is in a plane parallel to the first side and the second side, and the area of the carrier substrate, which is located on the second side between the at least one simulating the first watermark layer and observer, completed or partially hollow or full hollow, and covered in some areas at least, one located on the second side of the translucent colored layer, visible from the second side of the zone simulating the first Wodan the first mark layer visually recognized, as formed in some areas and opaque areas of the layer, which show protective information, and transmitted light from the second side show at least one watermark, which is different from the security information.

The observer recognizes the protected document according to the occasion and as usual when viewed first hand in transmitted light, the first watermark. On the other side, the observer sees in the incident light applied on the carrier substrate protective element or, respectively, formed in some areas and opaque areas simulating the first watermark layer, which show protective information, the form of which, however, against expectations do not match the shape of the first watermark. In transmitted light is again detected watermark, but in a mirror image. This effect is achieved, on the one hand, that is not recognizable by an observer in the incident light by the way, are directly visible, only a part or completely in some areas formed simulating the first watermark layer. While simulating the first watermark layer can be provided with areas of different light transmittance, which are distinguishable from each other only in transmitted light. On the other hand, the effect can be achieved by the fact that at least one non-is transparent to incident light layer, visible easily to the human eye, made only in some areas and a fully visible and additionally has areas of different light transmittance, which can be visually distinguished from each other only in transmitted light.

Thus, the observer perceives an area simulating the first watermark layer in transmitted light as opaque, when the transmittance of visible light is less than 5%, in particular less than 1%. How translucent the observer perceives in transmitted light area with a transmittance of visible light greater than 10%, in particular more than 20%. However, in the incident light to the observer is also perceptible in transmitted light as translucent areas can leave the impression opaque areas of the layer. If, for example, using a metal layer as simulating the first watermark layer, perceptible in transmitted light opaque and translucent zones when viewed in incident light reflect differently maximally by a factor of 10. Different by a factor of 10, the reflection clearly visible to the human eye, while the difference in the reflection to about 20% barely perceived.

Thus, if the factor is chosen, perhaps, less and/or reflection characteristics simulating the first watermark is consistent with the background, the human eye does not distinguish between differences in incident light and vesprini is no uniformly opaque surface.

When the carrier substrate, for example, made of paper and/or plastic can be the case when the protective element are sealed in the translucent carrier substrate and is in a plane parallel to the first side and the second side, and the area of the carrier substrate, which is located on the second side between the at least one simulating the first watermark layer and the observer, is made at least partially hollow, it is possible to realize the fact that the carrier substrate is made of at least two layers and that at least one protective element is located between these layers. Before connecting the layers with each other one of them provide a window opening and a window opening positioned over the protective element so that at least one simulating the first watermark layer is visible only partially. As an alternative solution, simulating the first watermark layer can also be fully visible and then in some areas cover translucent colour layer. In addition, in this case, it is also possible that the window opening is performed in two layers, and at least one protective element is combined with two window openings. Then the protective element on the first side partially or fully cover translucent color layer, and the second side cover colour layer in some the x zones, so simulating the first watermark layer on the second side in the incident light is visible only partially. On the first side, at least one simulating the first watermark layer is not readable or readable only partially. If at least one simulating the first watermark layer is readable also only partially on the first side in the incident light, preferably, when the second side is visible in the falling light of the different zones, at least one simulating the first watermark layer.

In this case, at least one translucent colour layer can be already a part of the protective element, or for sealing apply translucent layers of glue, so there is no need in his application after the embedding of the protective element in the carrier substrate. With respect to the optical masking the presence of window openings in the carrier substrate may be preferred integration translucent colored layers in the protective element in combination with an additional application of translucent colored layer after sealing protective element or when applying for sealing translucent layers of glue.

For the case of (b) preferably, when at least one simulating the first watermark layer on the first side and opposite to the first side of the second article is Ron protected document is covered, at least partially at least one translucent layer, at least one translucent layer on the first side and at least one translucent layer on the second side scatter incident on the second side of the light with varying degrees.

Finally, preferably, when in the case (b) the protective element is located on the second side, and simulating the watermark layer coated with at least one located on the second side of the translucent colored layer, or the protective element so embedded in the translucent carrier substrate, the protective element is in a plane parallel to the first side and the second side, but at different distances from the first side and the second side, or the protective element are sealed in the translucent carrier substrate, and simulating the watermark is covered with at least one located on the first side and/or the second side of the translucent colored layer, thus simulating the watermark layer when viewed from the second side of the transmitted-light shows at least one second image, which simulates the presence of the carrier substrate, at least one differing from the first water sign of the second watermark.

The observer recognizes in a protected document in case b) as usual when examining first the second side in transmitted light, the first watermark. On the other side of the observer does not see the incident light or sees only partially, at least, one simulating the watermark layer. However, in transmitted light, the observer sees on the second side different from the first watermark, the second watermark. This effect is achieved by the fact that the protected document executed between the simulating the first watermark layer and the first side, and between simulating the first watermark layer and the second side of the passing light is dispersed with a distinct degree. This leads to the fact that, for example, filigree holes in simulating the first watermark layer may be visible from the second side in transmitted light, but not visible from the first side.

For the case of (b) preferably, when the supporting substrate is formed of at least two layers of different material. The sealing of the protective element and the location, and the execution of translucent layers may be similarly already above the occasion and).

Falsification of the protected document according to the invention, in accordance with case a) and/or b) only difficult since you must maintain accurate and material dependent, at least one simulating the first watermark layer different layer thicknesses and/or holes or transparent areas, less is th least on one simulating the first watermark layer, or accurately determine the scattering characteristics of layers negotiate with the execution of simulating the first watermark layer.

For the case of (C) preferably, when at least one simulating the first watermark layer has areas with angle independent examination by light transmission.

In addition, preferably, when in the case (C)at least one first watermark in the transmitted light when the slope of the protected document, at least on one side of the protected document shows the kinematic effect and/or a three-dimensional effect and/or color-change effect.

The observer recognizes the protected document according to the case), as is customary when viewed first hand in transmitted light, the first watermark. On the other side of the observer also sees the watermark. However, when the slope of the protected document occurs on at least one side of the protected document kinematic effect and/or a three-dimensional effect, and/or color-change effect. The first watermark with the kinematic effect seems observer is moving, for example, as if showing people performed the movement. The first watermark with three-dimensional effect seems to the observer made space in the carrier substrate. The first watermark is color changing effect shows the observer different color or color at different viewing angles. These effects, which can be combined with each other, are achieved, in essence, the fact that the protective element is made with angle independent local light transmission, which is caused, essentially, by performing at least one simulating the first watermark layer, possibly in addition to the presence of the diffraction structures and maintaining the distance of the layers in the protective element.

The sealing of the protective element and the location, and the execution of translucent layers in this case you can also do the same as above occasion).

Especially preferred is a combination of cases (a)-(C), in which the protected document or the protective element has at least one zone, which is made in accordance with the case (a), and additionally has at least one second area, which is made in accordance at least one case (a), different from the case corresponding to the first zone. Thus, it can especially be combined effectively achieved effects. Various effects may be present in a single secure element or may be distributed in several protective elements.

Several similar and/or dissimilar made protective elements can be used on the same protected document. That is, for example, at least one first protective element can be located on the second side, and a second protective element can be embedded in the carrier substrate. In addition, on both sides of the protected document can be located protective elements, which when viewed on other relevant opposite side of the transmitted-light mimic the presence of the watermark.

It is also possible, at least partially overlapping the location of the at least protective elements, when viewed perpendicular to the plane of the protected document.

If used, at least one translucent colour layer, preferably when it is in color does not differ, or differ only imperceptibly from possibly painted border areas of the carrier substrate. Due to this, the presence of a protective element in these areas becomes optically hidden or not recognizable to the observer.

Preferably, when at least one simulating the first watermark layer has transparent areas and/or holes, the size of which, at least in one direction lie below the resolution limit of the human eye, i.e. is less than about 0.3 mm, Especially preferred are holes, the size of which, at least in one direction the AI lie in the range from 1 to 250 μm, in particular, in the range from 2 to 100 μm and, in particular, in the range from 5 to 80 μm. Such transparent areas or openings not visible to the human eye in the incident light, but visible in transmitted light on the basis of increased light transmittance.

In addition, preferably, when at least one simulating the first watermark layer has transparent areas and/or holes, with an average surface density of the transparent zones or apertures in the opaque layer is less than 10%. Such transparent areas or holes are in the incident light to the human eye, essentially, also invisible, but easily detectable in transmitted light on the basis of increased light transmittance.

In addition, preferably, when at least one simulating the first watermark layer has zones with different layer thickness. Zones with different layer thickness may seem to the human eye in the incident light opaque, however, areas with a smaller layer thickness easily differ in transmitted light on the basis of increased light transmittance from areas with greater thickness of the layer.

In the transparent areas, which are perceived equally with through holes, at least one simulating the first watermark layer material used for the formation of at least one simulating the first watermark layer, could be of such a small thickness that it does not have a significant or detectable influence on the properties of the light transmission of a protected document.

Structuring at least one simulating the first watermark layer or, respectively, the formation of holes or transparent areas can be implemented by using the method according to DE 102004042136 A1. When the thickness of the layer is adjusted so that the material for the formation of the layer is uniformly applied on the provided with a diffractive surface structures surface, while depending on the ratio of depth to width of surface structures formed locally different effective thickness of the layer.

At least one simulating the first watermark layer may be apparent in the incident light opaque areas, at least in some areas of the ever-changing layer thickness. In the alternative or in combination with this, at least, one simulating the first watermark layer may be apparent in the incident light opaque areas gradually changing the thickness of the layer. The formation of different thickness creates when viewed in transmitted light of different light transmission or, respectively, optical density and can also be implemented using the procedure of, according to DE 102004042136 A1.

In addition, preferably, when at least one simulating the first watermark layer has holes so that this layer is structured in the form of a thin point or line raster with raster width is less than 300 μm. It is particularly preferable when the layer is structured in the form of aperiodic point or line of the raster.

Thus, under the concept "point" refers not only to all the pixels of the image, but also point other geometric shapes, such as triangular, rectangular, elliptical, etc. point of the image. It is also possible point of the image in the form of symbols, art images, alphanumeric characters or sequences of characters. At this point or line are either uniform raster distance, either locally or constantly changing raster distance. In the alternative or in combination with it can change the magnitude of the surface points or lines.

Preferably, when forming a point or line raster zone, at least one simulating the first watermark layer, at least in some areas made substructuring. Under substructuring understood, for example, a phase shift of the partial number of image points or lines relative to Stalin the th raster. Other possibilities for substructurenotify are local change of curvature, the local change of the orientation of the image points or lines, the local change of the distance between points or lines, the local change in the form of image points or lines, executed in the form of various characters or image elements, etc. for example, may be substructurenotify only one single line due to the fact that the line consists of a sequence of letters, which, at least in some areas has a specific, readable content. Such substructuring can be read only with the help of auxiliary means, such as using a magnifying glass or by imposing other point or line raster screen verification.

Particularly preferably, when the protective element has at least two, at least in some areas located to overlap each other, simulating at least one first watermark layer. In this case, at least, between the two simulating at least one first watermark layer is preferably at least one transparent retaining the distance of the layer.

While the first and the second layer are preferably slightly different in their properties transmittance iatrogenia light partial zones. These different partial areas are located in the corresponding layer is preferably in accordance with a regular, periodic pattern. When this raster distances are preferably below the resolution capabilities of the human eye. However, depending on the angle of viewing of different partial areas of the first and second layer in the rays passing or reflected light interfere with each other, so that depending on the viewing angle for an observer creates another optical impression of the incident-light and transmitted-light.

In addition, in this case, it is possible that the first and second layers are in partial zones of the diffraction patterns, which act upon transmission or reflection of light. Due to this, you can optionally create depending on the viewing angle, the optically variable impression.

When the slope of the protected document, in the zone of overlap on each other, at least two simulating at least one first watermark layer is detected in the transmitted light depending on the angle of different light transmission and/or color. It is preferable to perform, in particular, for the case (C).

If there are three or more, located at a distance from each other by means of keeping the distance layers,simulating, at least one first watermark layers, you can optionally using different thickness of a transparent retaining the distance layer to improve the angular resolution is dependent on the viewing angle effect.

Preferably, when the protected document, there are at least two simulating at least one first watermark layer, which are each structured in the form of microscopically fine point or line raster, which when superimposed on one another to create, in particular, periodic moire pattern.

Preferably, when the protective element has an optically variable effect, which can be seen when viewed in incident light.

While the protective element has, in particular, the optically variable material, in particular an optically variable pigment, a liquid crystal material, a fluorescent material or a thermochromic material, and/or diffractive or refractive structure, in particular, the hologram, Kinegram (Kinegram®), stochastic matte structure, asymmetrical matte structure, macrostructure, light absorbing structure or microlensing structure.

Preferably, when the protective element has at least one adjacent at least one simulating at least one first watermark transparent layer is the first layer, which is formed, in particular, the diffraction structure. The transparent layer is preferably in the form of a varnish layer, in particular in the form of a layer of thermoplastic or solidified under the action of ultraviolet radiation varnish. When this transparent layer may be made without diffraction patterns and to serve as a protective layer for simulating at least one first watermark layer with the aim of covering at least in some areas is located on a secure document visible, simulating at least one first watermark layer and minimize the mechanical stress in the layer. In addition, the transparent layer may serve as a retaining layer distance between simulating at least one first watermark layers, or to give the layer a or the water mark in transmitted light, if it is not painted, painted look.

If the protected document has at least two simulating at least one first watermark layer between them is preferably at least one translucent color layer and/or a transparent layer may contain diffraction patterns.

Translucent colored layer is preferably formed using a pigmented layer of colored lacquer. This can be used as a crayon, what's the colors, and pure color. In particular, preferably, when the colored layers are formed photoresistive layers, which are made with the register in some areas to simulate at least one first watermark layer. While simulating at least one first watermark can serve as a mask for structuring photoresistive layers with registration.

In particular, the transparent layer has a multitude of microlenses, the thickness of the at least one transparent layer, at least approximately corresponds to the focal length of the microlenses.

However, the protective element has one or more transparent first layer and one second layer, which has many microsorb of one or more opaque the first partial zones and one or more second transparent partial areas, which is one of the first layers on its opposite second surface layer has a surface profile which forms the set of first microlenses, and that the thickness of the first layer or the second layer and located between the first layer and the second layer of one or more first layers approximately corresponds to the focal length of the first microlenses. Thus, the protective element has a first partial area, in which at least voroskoi made opaque; and he has a second partial area, in which all layers of the protected element is made transparent. In the area of the second partial zones of the protective element is completely transparent, i.e. the layers of the protective element is made in the area of the second partial areas transparent. Such a protective element creates when viewed from the front side and the back of the very different optical effects, which form a hard falsifiable protective sign. Formed in one of the first microlens layers form an optical display system, which can increase micropor. Using microlenses is selected, the image point of micropore for each microlens. Using microlenses this is a very bright, however, in principle, can work well as a shadow mask with point holes. Microtor consists of the first partial zones, which seem to be the observer or, respectively, the human eye is opaque, i.e. not transparent to light (due to the absorption or reflection of incident light), and the second partial zones, which seem to be the observer or, respectively, the human eye is transparent to light. Created so the overall impression shows transparent areas of the image, which, depending on the direction of viewing change their positions, so it may seem that is transparent the subzone image hovers in front of an opaque background. Images can appear behind the surface of the protective element, or before, or in its surface depending on whether the raster width of the microlenses is less than or greater than the width of the raster microimages. When the width of both raster exactly the same, but several rasters rotated relative to each other, then there is an interesting effect that images appear to be moving from left to right, when the protective element is moved slightly back and forth, and the images appear to be moving forward and backward, when the protective element is moved left and right. In addition, it is possible that the images are displayed mirrored or inverted, i.e. the image can be enlarged versions of microsorb (increase greater than 1), or the image can be mirrored or inverted versions of microsorb (an increase of less than -1). In contrast, when viewed from the rear side of the protective element seems opaque surface, which can display information in the form of a half-tone or gray image. This seeming contradiction between the two optical impressions manifests as incident-light and transmitted light, and is very noticeable and memorable. Inevitable errors of manufacturing relative activities is but the radius of the microlenses, refractive index and thickness of the layer of microlenses not adversely affect the functions of the protective element. As shown by the experiments, the thickness of the layer of microlenses may deviate from the nominal value of the focal length by 10-20%.

Preferably, when at least one simulating at least one first watermark layer is formed using at least one metal layer and/or at least one pigmented layer, in particular, highly pigmented layer of colored lacquer. While simulating at least one first watermark layer, at least when viewed in the incident light is to the human eye under normal lighting conditions, i.e. in daylight and artificial light, preferably opaque. However, when viewed in transmitted light, this layer may be, at least in some areas, pervious to light.

To create apparent to the human eye is opaque to the incident light of the metal layer is suitable, in particular, aluminum, silver, gold, chrome, copper, titanium, etc. and their alloys. When performing visible in transmitted light of the light transmissive or transparent zones it is important to know the individual parameters influence the formation of the metal layer in their dependencies and it is advisable to choose. Specially is Ino when the metal layers need to take into consideration the absorption of light, by which the sum of transmission and reflection of light is less than 100%. The observer perceives the area of the metal layer in the incident light as fully reflecting, when reflected 85% of incident light, and sees the area as transparent, when reflected less than 20% of the incident light, i.e. more than 80% of the light is skipped. These values can vary depending on the background, the lighting, etc. an important role in the absorption of light in the metal layer also plays a kind of metal. For example, chromium and copper reflect sometimes much less than gold and silver. This may mean that only 50% of the incident light is reflected, while the transmittance is less than 1%.

In addition, the transmittance may decrease additionally, when the light angle is different from the normal angle of incidence. This means that a metal layer, for example, in the area of the surface relief structure can be performed transmits light only in a limited cone of light incidence. Can also be provided that the metal layer seems opaque only at oblique viewing in incident light.

In addition, preferably, when at least one simulating at least one first watermark layer is formed from a combination of at least one metal layer and at least one is pigmentirovannogo layer.

The pigmented layer is preferably a layer that appears to the human eye under normal lighting conditions, at least when viewed in incident light, opaque. However, in transmitted light as well as in the metallic layer may be a light transmissive area. If simulating at least one first watermark layer on the protected document is at least partially visible when the combination of the metal layer and the pigmented layer can be formed visible in incident light colored patterns in combination with the metal patterns, and simulating at least one first watermark layer is thereby especially protected against forgery.

Preferably, when the carrier substrate is provided with a translucent protective printed image. Protective printed image is usually difficult to counterfeit due to their performance and materials used. So, on the notes is commonly used protective printed image of the filigree lines or, respectively, of gelosa, you can optionally use optically variable materials.

Particularly preferably, when simulating at least one first watermark layer when viewed in incident light and/or transmitted light shows the t of a grayscale image.

Particularly preferably, when the cover of the printed image contains a color material and/or magnetic material, and/or electrically conductive material, and/or optically variable material, in particular a fluorescent material, thermochromic material, the interference pigments or liquid crystal material. So, for example, fluorescent material protective printed image can be superimposed on at least one simulating at least one first watermark layer, the transmitted light can be observed an intense glare transparent to light areas or, respectively, the holes in at least one simulating at least one first watermark layer.

Preferably, when the protective element is formed of a layered film or gear conversion layer film. In the layered film has a self-supporting translucent or transparent carrier film, which is formed of at least one simulating at least one first watermark layer and optionally other layers, such as transparent layers, optically variable layers, translucent layers, adhesive layers, etc.

The transfer film has a generally self-supporting film on which the transfer layer, which is formed from at least one imitating, IU the greater extent, one of the first watermark layer and optionally other layers, such as protective layers, transparent layers, optically variable layers, translucent layers, adhesive layers, etc. of the Individual layers of the transfer layer is usually so thin that they, as well as the transfer layer, are not self-supporting.

Thus, the layered film is compared with the transfer layer is usually at least 50% greater thickness of the layer, and thus it is suitable for use in through the window in the carrier substrate. The carrier film conversion film is removed after fixing the transfer layer on the carrier substrate protected document. This requires a good separability of the carrier film from the transfer layer, which can be optionally specified to regulate by location waxy or silicone separating layer between the carrier film and the transfer layer.

A secured document according to the invention, can be banknotes, Bank cards, identification card, license, passport, security, testimony, or many others. Banknotes can be normal banknotes with the substrate of the protective paper or banknotes with the substrate in the form of a multilayer laminate made of plastic.

While the protective element can be repaired in an appropriate carrier under which oku or is applied onto it. The protective element can be performed directly in the protective substrate. When sealing a protective element, for example, in the paper it is possible to realize the fact that the protective element is already integrated in the manufacture of paper or payable between the individual, be connected to each other on the surface layers of paper, in particular glued or embedded between the still moist layers of paper. When the multilayer substrate can be attachment, bonding or laminating a protective element between the substrate layers. Cards with the main body of the card of plastic material or several layers of card from a different material, the protective element can be laminated between the individual layers of the card, Tiznit on the layer of the card and then close when pressure casting, or directly integrated into obtained by the process of molding the layer of the card, which in this case can also meet throughout the main body of the card. Sealing can also simulate optically, when the protective element is covered with a printed translucent layer, which is aligned with the optical view of the carrier substrate with embossed etc.

On figa shown in the top view a protected document 1 in the form of banknotes with a protective element 2 in the incident light. The banknote has the translucent carrier substrate 10 made of paper. On the second side 10b of the protected document 1 is covered with a protective element 2 in the form of a film element, which contains at least one simulating at least one first watermark layer 2A made of aluminium. The image of the other components of the banknote, such as protective of the printed image, etc. that are not provided for reasons of clarity.

On fig.1b shows the protected document 1 of figa in section along the line A-A'.

On figs shows the protected document 1, according figa, when viewed in transmitted light from the second side 10b. In this case, the observer is in the area of the protection element 2 simulated protective element 2 watermark 2'. Watermark 2' is composed of five wavy curved bands, which have different properties light transmittance. Both are located at the bottom and top strips have lower properties light transmittance than prisoners between bands, and therefore are seen in transmitted light as darker. Although the protective element 2 on the basis of simulating at least one of the first in Danau mark layer 2A in the incident light looks like a solid, specularly reflecting opaque surface of the aluminum, in transmitted light, this surface is different transmit light, and can be seen as divided into separate zones or bands with different tones of grey. This is achieved by simulating at least one first watermark layer 2A made with a different layer thickness. The thickness of the layer 2A is changed in the range from 10 nm to 100 nm, in particular in the range from 10 to 50 nm. Adjacent zones with different layer thickness is different for 2-50 nm, in particular 2-20 nm. However, this crucially depends on the material from which made simulating at least one first watermark layer 2A. In this case, simulating the first watermark layer 2A made of aluminum, and figa specifically shows the light transmission or, respectively, the optical density OD in normal light as a function of layer thickness (nm) aluminum layer.

Thus, simulating at least one first watermark layer 2A in the zone located above and below depicts the black stripes are made with a greater thickness than in the area both located between them, are depicted in dark gray stripes. In the area of the light gray bar in the middle of simulating at least one first watermark layer 2A again has a smaller layer thickness than in the area of the dark-sulfur the bands. Between the individual bands is when viewed in transmitted light bright dividing line. In the area of the dividing line simulating at least one first watermark layer 2A has a smaller layer thickness than in the area of the middle band. The thickness of simulating at least one first watermark layer 2A should be chosen so that the transmitted light can be achieved to different values of the light transmittance. As the observer perceives the incident-light opaque aluminum surface, it is all the more surprising is the appearance in transmitted light different in form and execution watermark 2'.

On fig.1d shows the protected document 1, according figa-1C, when viewed from the first side 10A in transmitted light. This watermark 2' appears to be identical to the view from the second side 10b, only in mirror image.

On figa shown in the top view a protected document 1' in the form of banknotes with a protective element 2 in the incident light. The banknote has the translucent carrier substrate 10 made of paper. On the second side 10b of the protected document 1' is made embossed protective element 2 in the form of a film element, which includes simulating at least one first watermark layer 2A made of aluminium. Between simulating at least one first watermark layer 2A and the observer which is printed in a pattern translucent layer 3 having a star-shaped hole, which is formed from a layer of pigmented lacquer with color similar to the color of the border of the carrier substrate 10, and masks the actual dimensions simulating at least one first watermark layer 2A (in this case, the shape of a cross, which is shown by the dashed lines). Thus, simulating the first watermark layer 2A directly visible only in the zone of the star-shaped holes in the translucent layer 3, while its other areas are not visible in incident light. Other components of the banknote, such as protective of the printed image, etc. that are not shown in this case for clarity.

On fig.2b shows the protected document 1', according figa, in section along the line B-B' You can clearly see that the star-shaped hole in the translucent layer 3 leaves uncovered only a portion simulating the first watermark layer 2A.

When viewed in transmitted light protected document 1'shown in figa, shows a similar watermark 2' (see figs)as the protected document 1 figa, but with the circuit in the form of a cross. Thus the observer sees in the area of the protective element 2 simulated protective element 2 watermark 2'. Although the protective element 2 simulating at least one first watermark layer 2A in the incident light only shows a solid, star-shaped reflecting mirror C is srochnuu the surface of the aluminum, when viewed in transmitted light layer 2A is divided into separate areas, in particular bands, with different permeability to light, in particular, the tones of grey. This is achieved by opaque to incident light layer 2A in some areas made with a different thickness and/or has many holes, the distance between which, in at least one direction is less than 0.3 mm, for example, the holes have a diameter of from about 2 to 100 μm, respectively, occupied by a single hole size is approximately 3-75·103μm2and they are located at a distance from each other in a raster with raster width from 20 to 300 μm in the X direction and from 20 to 300 μm in the direction Y. the Proportion of the surface of the holes is between about 0.003 to 10%. Since the observer in the incident light sees a star opaque aluminum surface, it is all the more surprising is the appearance in transmitted light different in form and execution watermark 2' cross the path.

Shown in figa protected document 1' shows when viewed from the first side 10A in transmitted light image similar to that shown fig.1d image, but with a cross-shaped contour. When this simulated watermark is visible is identical with the second hand, but in a mirror image.

Figure 3 is shown another protected document 1" in the form of banknotes with embossed it with the protective element 2. Simulating at least one first watermark layer 2A is formed of separate, spaced in a regular raster width 5 are 300 μm, in particular 10-100 μm, and seemingly opaque to the incident light of the image point of aluminum (not shown separately), between which is visible when viewed, at least through the microscope, the carrier substrate 10. Point of the image cover 80-100% of the surface. An additional decrease in the proportion of the surface of the image points can be achieved when the reflection simulating the watermark layer 2A coordinated with the reflection of the background, respectively, of the carrier substrate 10, for example, by using the scattering microstructure. Simulating at least one first watermark layer 2A shows the incident-light half-tone or grey-scale image of the five curved stripes in two different tones of grey.

On fig.3b shows the protected document 1, according to tiga, when viewed from the second side 10b in transmitted light. On the basis of different layer thickness of the individual image points simulating at least one first watermark layer 2A in transmitted light is visible first watermark 2' in zones of different permeability to light. Thus, the average curved strip of transmitted light is more permeable to light than strips on top and bottom, and, also, recognized five vertical filigree lines with high permeability to light.

On figs shows the protected document 1, according to tiga, when viewed from the first side 10A in transmitted light. Thus the observer sees in the mirror relative to the first watermark 2' is similar to the second watermark 2", which, however, does not show the five vertical filigree lines with high permeability to light. This realized the fact that the carrier substrate 10 so strongly scatters light passing in the area made especially light filigree lines protective element 2 on the first side 10A that they are not visually visible in transmitted light.

On fig.3d shows a section of a protected document 1" on line C-C' figa. The protective element 2 has a transparent layer 3A adhesives hot curing, which is simulating at least one first watermark layer 2A and the transparent lacquer layer 3b and pasted on the carrier substrate 10. While the protective element 2 is formed by the transfer layer of the transferable film and applied by way of transfer to the carrier substrate 10.

On file shown in the context of the protected document 1" with asymmetrically embedded in the carrier substrate 10 made of paper protective element 2, which, in principle, performed as a protective element 2, according figa-3d, and leaves in transmitted light and the counter-intuitive impression. Incident-light protective element 2 is essentially not visible from any side 10A, 10b protected document 1". The protective element 2 is made in the form of laminated film and has a transparent lacquer layer 4A, simulating at least one first watermark layer 2A and the transparent lacquer layer 4b. However, the protective element 2 and the first side 10A is more strongly scattering light passing paper layer than between the protective element 2 and the second side 10b. For example, a paper layer between the protective element 2 and the first side 10A on 10-95% thicker than the paper layer between the protective element 2 and the side 10b, when the total layer thickness of the carrier substrate 10 from 50 μm to 2 mm, in particular from 50 μm to 1 mm Sealing protective element 2 in the carrier substrate 10 is in this case already during the manufacture of paper.

Thus, in transmitted light due to the increased on one hand the number of paper layers or, respectively, increased thickness of the paper layer is formed over a long path of light, and a stronger scattering of light, so that on the one hand to the protective element 2 comes less light. When examining the protective element 2 from the first side 10A is observed similar to that shown figs watermark. In contrast, when viewed from the second side 10b n is observed similar to that shown fig.3b watermark. Filigree lines are visible in transmitted light only from the second side 10b, but not visible from the first side 10A.

On figa shows another protected document 1"' in the form of a certificate with a protective element 2, in which incident light is dependent on the viewing angle, the optically variable effect. Thus, the observer 100 protected document 1"' sees with the first direction examining the protective element 2 with simulating at least one first watermark, seemingly in incident light opaque layer 2A, the first image is recognized by the house. The first image is created using made in layer 2A diffractive first relief structure.

From the second viewing direction of the observer 100 recognizes, as shown in fig.4b, also the protective element 2 with simulating at least one first watermark, seemingly in incident light opaque layer 2A. However, in this direction, examining recognized not the first image, and at the expense included in the layer 2A of the second relief structures of the second image in the form of roses. While the first and second relief patterns are formed, for example, diffraction gratings with different relative to each other azimuthal angles or different, asymmetrical relief structures, for example, concentrating diffraction is setkani with different inclination of the side surfaces.

On figs shows the protected document 1"', according figa and 4b, in transmitted light and in a slightly enlarged scale. Not visible neither the first nor the second image, and third image in the form of a hare on a colored background as watermark 2', which is also visible from the first side 10A.

The protective element 2 for the implementation of the protected document 1"' made with simulating at least one first watermark layer 2A made of aluminum, containing also the diffraction patterns, which are thin raster width which, in at least one direction is less than about 0.3 mm, the First group of raster surfaces contains the first diffraction patterns, which are used to create the first image when viewed in one direction. The second group of raster surfaces contains a different second diffraction patterns, which serve to create a second image when viewed in the second direction. The third group of raster surfaces contains holes, which when viewed in transmitted light increases the light transmission in some areas to create a third image. Opaque to incident light layer 2A is not visible to the human eye in the incident light holes, which, however, are recognizable in transmitted light. This Rel is relative value and the local frequency of the holes varies with the purpose of creating in the passing light of different tones, accordingly, levels of gray. In the area of the holes can be located transparent to light colored layers and/or posted on the translucent reflective layer is transparent to light diffraction patterns, with the aim of creating in transmitted light color effects and/or optically variable effects. To ensure that the holes did not interfering influence visible in incident light of the first and second images having apertures, a raster surface alternately located near diffraction raster surfaces. In this zone simulating at least one first watermark layer 2A, which correspond to the third image, seem incident-light metallic specularly reflective. In the alternative, may be provided by third structure in the form of a metal structure in the area with openings raster surface, which has the characteristics of scattering, similar to the carrier substrate 10, so that the area of simulating at least one first watermark layer 2A, which correspond to a third image that is not visible in incident light. In addition, there may be also absorbing the light of the fourth diffraction structure in the areas of simulating at least one first watermark layer 2A, which correspond to one third of the th image, so they are in a falling world looks dark. To provide additional color to the third image, preferably with the drive to the holes have at least one translucent or transparent colored layer, in which incident light is hidden for simulating at least one first watermark layer 2A, however, is detected in the transmitted light, and gives a third color image or at least create colored areas, this may be one or more colors.

In addition, it is also possible that the fourth group of raster surfaces covered by third structures, and the fifth group of raster surfaces are covered with the fourth structures, so along with the first, second and third image using a protective element 2 is still the fourth and fifth image in which the incident light are formed in the third and fourth and, respectively, third and fifth groups of raster surfaces. In addition, can be superimposed on the effects filigree cinegamma®that does not detrimentally impact on the watermark effect and serves to distract the eye from the raster and hide it.

When this raster surfaces of the first and third groups of raster surfaces preferably are arranged alternately in accordance with a regular Rast is om, for example, in the sequence of raster surface of the first group, a raster surface of the second group, a raster surface of the third group, a raster surface of the first group, etc. During this period of repetition in the sequence is selected is less than 0.3 mm

On figa shows another protected document 1"in the form of a certificate with a protective element 2 (see also figa), which is embedded in the carrier substrate 10 of the light-scattering paper on the border with the surface and simulates in transmitted light when viewed from the first side 10A having a three-dimensional watermark 2'. While the protective element 2 has at least two located at a distance from each other simulating at least one first watermark layer 2A', 2a" of opaque, painted in black lacquer (see fig.5d), which acts as a filter for light of certain angles of viewing the retaining distance layer 5 made of polymer film, which skips coming from the second side 10b, the scattered light only a certain angular range. Two simulating at least one first watermark layer 2a', 2a" equipped with every holes, and the holes are superimposed on each other so that the transmitted light depending on the angle of viewing different areas of the protective element 2 is passed light is. So, in transmitted light under the first viewing angle, as shown in figa, you can see the first three-dimensional image, in this case built into the folds of the ribbon.

If the protected document 1""according to fig.5b, seen from another angle in transmitted light, visible at the base of the shift, respectively, changing the position of the light transmissive areas of three-dimensional ribbon from a different perspective. This change in perspective can occur continuously or discontinuously when the angle of viewing.

On figs shown in simplified form in the context of a protected document from figa and embedded in the carrier substrate 10, the protective element 2.

On fig.5d shown the protective element 2 of figs in section and on an enlarged scale. Shown holding the distance layer 5, which on each side has one of simulating at least one first watermark layers 2a', 2a", which are each equipped with holes, through which, depending on the acting as a filter retaining the distance layer 5 light of a specific angular direction. In addition, there may be an optically variable element 6 in the form of a volume hologram amplitude hologram or diffractive surface structure, which is visible in transmitted light, however, in the incident light, essentially, is not readable is.

On figa shows another protected document 1 embedded in the carrier substrate 10 of the light-scattering paper on the border with the surface of the protective element, which when viewed in transmitted light from the first side 10A simulates the presence of a moving watermark 2'when you change the viewing angle. While the protective element has, as already, in principle, presented at figa-5d, at least two simulating at least one first watermark layer, which are located at a distance from each other by acting as a filter retaining layer distance and equipped with every holes, and the holes superimposed on each other, that in transmitted light depending on the angle of viewing different areas of the protective element transmit the light. So, in transmitted light under the first viewing angle visible watermark 2' in the first image, in this case in the form of a split in the middle of a circular ring.

On fig.6b shows the protected document 1 of figa in transmitted light, however, a different angle of viewing. By shifting or changing the position of the light transmissive areas watermark 2' is visible in the second image, in particular a circular ring in a different spatial orientation. However, changing a position of the circular ring can be observed is ararauna when the angle of viewing, or it can happen suddenly.

On figa shows a transverse section of the manufacturer of the protective element 2, according fig.7b, to create visible only on one side of the protected document watermark effect. Film carrier 7 of transparent polyethylene terephthalate (PET) with a thickness in the range from 12 to 50 μm is covered on one side with a layer 8 of hardening under the action of ultraviolet radiation on the replication lacquer and replicate it microlens 8A. Microlens 8A is preferably reflective and have a thickness or depth of the structure is usually 2-50 μm and the diameter (perpendicular to the plane of the layer 8 replication lacquer) is usually 5-100 μm. On the opposite the microlenses 8A side of the film carrier 7 is applied on the entire surface of the metal layer 12 of aluminum with a thickness of 50 nm, which caused the information in the form of a Euro sign. Information is created by the application executed on the entire surface of the metal layer 12 on the opposite film carrier 7 positive side photoresistive layer 9. Then, through not illustrated here, a mask that contains information, perform illumination with UV light (see the arrows) from the side of the microlenses 8A. Ultraviolet light falls on the lenses 8A and focuses them or going to the beams, so from the replication layer 8 out only the light beam on each microlens 8A. Beams of light fall through the film carrier 7 on the metal layer 12 and, due to sufficient bandwidth having a thickness of 50 nm aluminum layer to ultraviolet radiation to pass through it to the positive photoresistive layer 9. Then lit areas photoresistive layer 9 is removed in the washing process and the liberated areas of the metal layer 12 is removed by means of etching. In a metal layer having openings that are oriented with impeccable register to the microlenses 8A. Finally, removing the photoresistive layer 9 and release provided by the holes of the metallic layer 12, which becomes simulating the first watermark layer 2A (see fig.7b). In the alternative, the holes in the metal layer can be created also by using laser ablation, while preferably used a metal layer of aluminum with a thickness of 20 nm or a layer of tellurium layer thickness of 50 nm.

On fig.7b shown in cross section made according figa, the protective element 2, which is for sealing in the carrier substrate protected document can simulate a watermark with a particularly unusual optical effect.

On figs shown in the cross section of the protective element 2, according to the fig.7b, which is completely embedded in the carrier substrate 10 is protected document from paper and glued it on both sides. The carrier substrate 10 is made relatively weak scattering and thin.

For bonding on both sides of the protective element 2 has a transparent layer 13A, 13b of glue on the entire surface or only on part of the surface (for example, in the form of linear or dot screen). The thickness of layer 13b, which is located on the border with microlenses 8A, it is necessary to choose negligibly small relative to the depth structure of the microlenses 8A, so as not to negatively affect the optical action of the protective element 2. Edge with simulating the first watermark layer 2A layer 13A glue can be made considerably thicker. The protective element 2 in the incident light is not visible neither from the first side 10A or the second side 10b of the carrier substrate 10. With the first side of the carrier substrate 10, the observer sees in the passing light of the first watermark with light dynamic movement effect, which transmits information in the form of a Euro sign, due to the fact that the simulating the first watermark layer 2A passes through the holes 11, only part of the incident light. When viewed from the second side 10b of the observer, however, does not see the watermark, because the lenses lead to the fact that all of the incident light is focused on them and pass the t through the holes 11. Followed by the material of the carrier substrate 10 disseminates or distributes evenly focused light before the light reaches the observer's eye, so to the surprise of the observer from the second side 10b cannot distinguish differences in light or, respectively, the watermark in the carrier substrate 10.

On figa shows a graph of light transmittance or optical density OD of the aluminum layer from the layer thickness d (nm) under normal lighting. The observer perceives the aluminum layer as translucent when light transmission is greater than 10%, in particular more than 20%. This is true for aluminum with a thickness of up to about 10-15 nm.

On fig.8b shows a plot of the transmission/reflection of light, respectively, the optical density OD of the silver layer from the layer thickness d (nm) under normal lighting. The observer perceives a silver layer as translucent when light transmission is greater than 10%, in particular more than 20%. This is true for silver with a thickness of up to approximately 19-27 nm.

If you are using a layer of gold, a layer thickness of 40 nm is obtained light transmittance less than 10%, i.e. an opaque layer.

The above embodiments of the protected document to simulate optically amazing watermarks can easily be combined with each the other location on the same protected document for additional protection against counterfeiting.

SUBSTANCE: invention relates to multilayer articles - data media with an optically variable structure. The data medium which characterises its authenticity has a coating in form of a printed bitmap, and three-dimensional bitmap. The three-dimensional bitmap lies relative to the coating such that it at least partially lies on the coating. The width of the lines and the distance between the lines of the printed and three-dimensional bitmaps and relative orientation of the bitmaps is selected such that they form a moire pattern; when the medium is viewed at right angles to the surface, the coating is completely distinguishable, and the moire pattern is hidden. When viewing at an acute angle, part of the coating lying on the surfaces of the three-dimensional bitmap, lying parallel to the direction of viewing or closed from the viewer by elements of the three-dimensional bitmap, is not distinguishable, but part of the coating lying on surfaces of the three-dimensional bitmap facing the viewer and not closed from the viewer by elements of the three dimensional bitmap, is distinguishable, as a result of which the moire pattern becomes visible, where the boundary of two colours of the printed bitmap mainly lies on inclined areas of the three-dimensional bitmap. The effect of movement of boundaries of colour bars on the medium is observed when the angle of inclination of the medium is changed.

EFFECT: invention improves the protective feature with a moire effect by obtaining a dynamic effect which simplifies authentication of the medium by an unskilled user.
