The present invention relates to a valuable document, such as a security or identity card, with a protective element containing at least one material with optically variable properties, create different color effects when rassmotreni the printing ink, containing such material with optically variable properties.

Given the high quality color copies that you can get on a modern copy equipment, valuable documents, such as banknotes, identification cards and so on, to protect them against forgery, you need to provide an additional protective elements that can not be copied, respectively, do not allow you to get a copy of it, matching the original. With this purpose they used an optically variable properties, such as holograms, forming an interference layer elements or liquid crystal materials, which create different color effects when viewed from different angles of view. These items due to overflow or play their colors and paints form a solely visual, easily recognized visually protective trait that allows even non-professional easy to distinguish a photocopy, in which there is no specified spillover effect colors from the original. However, an optically variable properties only to a limited extent, amenable to automatic control and subject to high maintenance cost.

In the application EP 0435029 B1 describes a valuable crystals. Thus, in particular, as a protective elements proposed to use liquid crystal polymers, which in their manufacture on appropriate technology are at room temperature is similar to the plastic solid with a strong overflow of colors. Such polymers can be used in the manufacture of protective elements of different types. For example, a layer of liquid crystalline polymers can be coated polymer film, and then cut the fabric into narrow ribbons or strips that can be incorporated into the paper or other material as a protective threads. In the application EP 0435029 B1 has also been proposed to produce transferable tape, in a layered structure which includes a layer of liquid crystalline polymers. In addition to the optically variable properties of liquid crystalline materials have also svetlopolyanski properties, which makes it possible and automatic control of the protection element. Since, however, the ability of liquid crystal materials to the polarization of the light is only weakly pronounced effect, which significantly reduced as a result of external influences, such as pollution of documents and have them bend and SCR is automatic control, too high.

Based on the foregoing, the present invention was used to develop a valuable document with optically variable properties of the protective element, which not only would visually well-recognized optically variable effect, but would be more effective automatic control.

The basic idea of the invention, which is unexpectedly simple in implementation, is not to improve the ability to automatically control the material with optically variable properties, and to combine this material with at least one distinctive substance that can easily and reliably be automatic control and at the same time does not detract visually distinguishable optically variable effect created by the material with optically variable properties. In accordance with this proposed invention the protective element comprises at least one material with optically variable properties, create different color effects when viewed from different angles of view, and at least one amenable to automatic control or recognition of distinctive prophetic the key variable properties. This protective element can be manufactured as a separate element, which subsequently fixed to protect against forgery of a valuable object or the subject, or it can be performed directly on the most valuable object or subject, for example in the form of a printed image.

As a distinctive substances can be used, for example, phosphors, conductive polymers or various types of carbon black, absorbing infrared radiation substance, and magnetic or thermochromic materials. It is preferable to use distinctive substances that are transparent to radiation in the visible region of the spectrum.

In the case of phosphors is most appropriate to use phosphors, luminescent radiation which lies outside the visible spectrum and has a narrow strip, which is now amenable to automatic recognition. It is preferable to use inorganic phosphors, however, depending on a particular purpose may be the use of other phosphors.

Magnetic materials are often black, respectively own dark colors. However, such materials, when used in appropriate concentrations, however, dopustenjem. This is due to the fact that dark magnetic materials absorb scattered radiation around the material with optically variable properties, thereby increasing the optically variable effect.

As the material with optically variable properties you can use the liquid crystal material, preferably a liquid crystal polymer material or materials forming the interference layer. It was found that it is most preferable to use materials with optically variable properties in the form of pigments, respectively, of the particles of the appropriate size, distribution of particle size and shape factor, so they can be added to any other materials. When it is possible to use pigments with an opaque paint or pigments without such an opaque paint. The latter are almost completely transparent, and therefore their color affects the background color. It is also possible to use liquid crystals in the form of microcapsules.

According to one preferred options protective element can be formed colored layer applied at least in some parts of the valuable document. Such a colored layer contains mesta. When the color layer is applied by printing such as screen printing, elastography or metallographic printing, the content in printing ink pigments with optically variable properties depending on the distinctive substance is from 10 to 30 wt.%, and the very nature of this distinctive substance is from 0.01 to 30 wt.%, in each case, calculated on binder. When used as a distinctive substances phosphor is added in an amount of from 0.01 to 30 wt.%, preferably from 0.01 to 10 wt.%, and, with the use of magnetic materials can be added in an amount of 5 to 80 wt.%, preferably from 10 to 20 wt.%. If as a distinctive substances used conductive polymers, this polymer can serve as a binder for the color layer.

In another embodiment, the protective element may be in the form of strips or threads, which is either fully placed on the surface of the valuable document, or forms a so-called security thread, which is only partially free access to the surface of the valuable document. In the composition of the material of the protective element in this case is a polymer containing, for example, a material with optical AC is th material can also apply a color layer, containing material with optically variable properties and distinctive substance. According to another variant in the composition of the material of the protective element may include an electrically conductive polymer material on which or in which there is a material with optically variable properties.

In accordance with the following variant of execution of the invention the protective element can be made also in the form of a polymer film that contains a material with optically variable properties and distinctive substance. Such a polymer film can be used, for example, as a protective coating on certain areas of the valuable document or as a continuous coating film covering the document, such as the identity on the entire area of its surface.

Material with optically variable properties and distinctive substance can also be added to the polymer granulate, which is then processed into finished plastic products. To this end, this granulate can be processed, for example, by extrusion or injection molding.

In addition, the protective element can be performed in a multilayer conversion element in a layered structure which includes material is n in the form of a self-supporting labels, consisting of a substrate and located on it or in it a layer with optically variable properties and distinctive substances. In another embodiment, the conversion element may not have a substrate. In this case, the conversion element is made in the form of a film hot stamping, based after the transfer of transferable protective element on the corresponding surface again to remove.

Distinctive substance and material with optically variable properties in principle does not necessarily apply to a valuable object at the same time. For example, a valuable object, you can first apply a distinctive matter, and then on top of it to deliver the material with optically variable properties.

This approach is most preferable to use in cases where as a distinctive substance use dark magnetic material or conductive carbon black, and as a material with optically variable properties used almost completely transparent material without or with a small amount of opaque paint. In this case, first put distinctive substance in the form of a printed image, and then on the same plot put a layer of material with optically variable properties, which the VA. Because the dark background absorbs radiation passing through the material with optically variable properties, as well as diffuse radiation, optically variable effect is most clearly seen in the plot of the magnetic printed image.

The security of such a protective element against forgery could be further enhanced when used as a distinctive substance of magnetic material and adding in a magnetic layer of carbon black. Carbon even at concentrations from 1 to 5 wt.% gives good conductivity, which can be easily detected using the appropriate equipment.

Another possibility to further improve the degree of protection protective element against forgery consists in the application of distinctive substances in the form of code or alphanumeric information. In the simplest case, this code may be a bar code. If the code should not be visually discernible, there can be provided plotted with respect to the registration of the mask layer that are not visually different from the code, but does not include distinctive substances. Such masking may also be useful in the case when coderunner angle, it is possible under certain conditions to detect the presence of gloss.

When automatic control of the protection element can be analyzed by several different properties. Most of the materials with optically variable properties, primarily liquid crystal materials are transparent to infrared radiation. When combining such materials are transparent to radiation in the visible region of the spectrum phosphor, which emitted radiation lies in the infrared region, with automatic control to detect material with optically variable properties you can analyze the spectral composition of radiation in the visible and infrared wavelength ranges. At the same time on the same plot, you should verify the presence of specific physical properties, such as luminescence or conductivity of distinctive substances.

If distinctive substance is opaque to determine or measure its properties however can be used the same principle. In this case, as the reference value used aliasing material with optically variable properties and distinctive substances in the visible region of the spectrum.

Furthermore, the material with Oprah can be set using the corresponding optical sensor. As thermochromic materials can be used, for example, are suitable for this purpose, liquid crystal materials, which have the ability to change color and are characterized by rapid response to an impact.

The protection proposed in the invention is a protective element against forgery can continue to improve even more through the use of several materials with optically variable properties and/or distinctive substances that may be located in the same or in different layers of the protective element.

If the material with optically variable properties of the used liquid crystal material, and this layer can be used for transmission or reproducing additional information. This is due to the fact that liquid crystals ways to divide the incident unpolarized light into components with different polarization. Depending on the chemical composition of the liquid crystal material from them will affect only one of these components. According to the invention, this property can be used to represent different information. So, for example, using a printing ink containing leopoliensis idcok is sealed with respect to the registration of the printing ink, containing propositi liquid crystal material. Under normal lighting both colors look the same, and therefore the information printed one of the colors in these conditions are not visually distinguishable, respectively, are not apparent. This information is visible only when seen through the corresponding polarizing filter because it passes through the radiation reflected only one of the liquid crystal material, and therefore on the border between the two printed layers there is noticeable luminance contrast.

One or both of the liquid crystal materials can optionally give a thermochromic properties, so when appropriate heating of such material, for example coming from the finger of a man of warmth, there is a color change that can be automatic and/or visual detection or control.

If both the liquid crystal material have a thermochromic properties, there may be other options for their application. For example, such materials you can choose from so that they both changed at the same temperature, its color changing, however, in different colors. This approach also is whether changes its content. It is preferable to use materials which under normal conditions look the same, and when heated acquire a color contrasting with each other. In addition, you can also use materials which when heated become transparent or opaque.

The selection of the chemical composition of liquid crystalline materials can be given additional thermochromic properties. However, to obtain the optimal set of individual properties, it is advisable to mix some liquid crystal materials, each of which has a special property. In other words, it is possible, for example, choose two basic liquid component, which have the ability to right - or left-handed polarized light, and mutually agreed-reflective characteristics, but are thermochromic. They are mixed in the following with the appropriate thermochromic liquid crystal materials.

Proposed in the invention, the protective element can not only be used to protect such valuable documents, such as banknotes, identification cards, passports, stocks, etc., but can also be placed on any protected from a fake objects or items, such as motrine for example, some variants of its implementation with reference to the drawings, showing:

in Fig.1 is proposed in the invention is a valuable document

in Fig.2 is a first embodiment of a protective element according to the invention,

in Fig.3 is a second embodiment of a protective element according to the invention,

in Fig.4 is a third embodiment of a protective element according to the invention,

in Fig.5 is a fourth embodiment of a protective element according to the invention,

in Fig.6 is a fifth embodiment of a protective element according to the invention,

in Fig.7 is a sixth embodiment of a protective element according to the invention,

in Fig.8 is a seventh embodiment of a protective element according to the invention,

in Fig.9 is another embodiment of a protective element according to the invention, shown in the top view, and

in Fig.10 - special embodiment of the liquid crystal layer according to the invention with the right - and lesoposadki properties.

In Fig.1 presents the proposed invention is protected from a fake document 1, which in this case is bill. In this bill sealed (woven) so-called security thread 2, which in certain areas goes directly to the surface of the paper. Located between these sections within the paper web sites thread 2 pokazatelnyy proposed in the invention of the printing ink. This imprint 4 forms a protective element in accordance with the invention. Since the entire seal, which seal is a valuable document, usually not entirely put offer in the invention of the printing ink, the stamp 4 is a locally constrained protective element, the border of which is shown in Fig.1 in phantom line in zone 5. However, if necessary, and the entire seal can be applied proposed in the invention of the printing ink.

In the structure proposed in the invention of the printing ink includes a material with optically variable properties, such as liquid crystal pigments or forming an interference layer pigments, and at least one amenable to automatic detection of distinctive substance. In the composition of the pigments with optically variable properties may include an opaque paint, if the print should have certain coating properties. In that case, if you want to keep visible button under the layer of pigment information or colorful layers, use transparent materials with optically variable properties without opaque paints.

Amenable to automatic detection of distinctive substance may constitute Liu is ostoic is what they do not impair the visual color effect material with optically variable properties and at the same time are not visually distinguishable. Because counterfeiters are generally limited to the imitation of the appearance of the securities subject or object, such tampering can very easily spot checking amenable to automatic detection of the distinctive properties of a substance.

You can also use magnetic pigments, primarily black magnetic pigments. However, the concentration of the magnetic pigments to choose from so, in order not to impair the visual impression created by pigments with optically variable properties. Adding magnetic pigments in small concentrations, they even enhance the visual impression created by pigments with optically variable properties, such as pigments absorb scattered radiation.

In Fig.2 shows another embodiment of the proposed invention in the protective element. In this case, such a protective element is a security thread 20, which, as shown in Fig.1, can be embedded in the material of the banknote as security threads, facing certain areas on the surface of this banknote. Sneaky. On this substrate is a layer 7 with optically variable properties, which contains distinctive substance 8. Layer 7 with optically variable properties can represent the printing layer or film layer. If this layer is colored, distinctive substance 8 may, for example, to serve as a binder.

In Fig.3 shows another embodiment of the proposed invention in the protective element 21. In this case, the protective element is a self-supporting film 9, which has an optically variable properties and which includes a distinctive substance 8. Such a film can be pasted in the form of labels on the protected from a fake object or an object of any type to protect against counterfeiting of the product concerned. In another variant of such a film can also be used as a coating film applied, for example, passports and identity cards. In addition, the film 9 can also be cut into strips or strips of a certain width, fastened on the valuable document or any product or closed up in the material of the securities as security threads.

In Fig.4 shows the proposed invention in a bill of material 22, in sloys the Specified conversion material consists of a substrate 10, which can be applied to the separation or the intermediate layer 11, which allows to separate the layered structure from the substrate. Layer 12, which may be in the form of a printed layer or film layer contains distinctive substance 8 and the material with optically variable properties. And, finally, the layer 12 may be covered with an adhesive layer 13, preferably a layer of hot-melt adhesive. Obviously, in a layered structure bill of material 22 may be provided and additional layers in accordance with the specific purpose of its application. If layer 12 is, for example, a printed layer, it may be expedient to provide between the separation layer 11 and layer 12 another protective layer that protects the protective element from the harmful effects of environmental factors after his transfer to a valuable document.

The composition of the specified protective layer can also be entered distinctive substance. In another embodiment, the distinctive substance can only be entered in this protective layer, and in this case, the layer 12 will contain only material with optically variable properties.

To transfer the image to the above bill of material 22 in his later impose on semisemi sites in the resulting layered structure located on the substrate 10, which is firmly connected with the material document and subsequent separation of the substrate 10 remains in this document.

Similar to the above self-supporting film 9 bill of material 22 can be used to protect any other objects or items.

In Fig.5 in cross section showing the valuable document 14 proposed in the invention, the protective element 23 made another version. On the surface of the valuable document 14 has a print (printed image) 16 dark color, containing distinctive substance. This seal 16 can represent, for example, any code or alphanumeric information. On top of this impression on a large area of land is the material 15 with optically variable properties, which does not contain or contains only a small amount of opaque paint. At the same time as such material can be used, for example, liquid crystal polymer materials or forming an interference layer materials produced by the company Merck under the trademark IRIODINE. Such materials are preferably added as pigments for printing ink or applied Ki is aetsa on the background areas, where is the dark printed image 16, and in other areas it is practically not noticeable due to its transparency, and due to the resulting scattered radiation.

Dark printed image 16 can be obtained by containing magnetic pigments in the printing ink or by using a printing ink, which is blended with other distinctive substance. However, this printing ink can represent, for example, which transmits infrared radiation of the black printing ink, to which is added one or more phosphors with emission in the infrared region of the spectrum. In another embodiment, can also be used containing carbon black printing ink having a conductivity, which can be easily detected with the proper equipment.

To additionally increase the degree of protection in case to cause the printed image 16 amenable to automatic control or recognition of printed ink only in certain areas. In other words, in this case part of the whole printed image 16 is applied dark printing ink that contains no magnetic pigment or phosphor, and the rest put the tools not only to establish the existence of distinctive substances in the material with optically variable properties, but also to analyze its distribution in this material.

It is obvious that the printing ink used to produce the printed image 16 may contain several distinctive substances, for example a mixture of magnetic pigments and phosphors. You can also use multiple materials with optically variable properties.

It is shown in Fig.5 an embodiment is most preferable to use the need for using a printing ink with optically variable properties of printed images or prints with high resolution. This is due to the fact that due to the necessary dimensions of the lamellar pigments and particulate forms of most materials with optically variable properties cannot be used for printing fine patterns with high resolution components of their elements, for example of gelosa (i.e., patterns of thin interwoven lines) with the thickness less than 0.1 mm as positive or negative (negative) of the printed image. Therefore, such materials are usually applied by screen printing. In contrast, a thin line of thickness less than 0.1 mm can usually be obtained only with the help of offset printing, timeoffset or similar metodologi type, that allows the use of printing inks with distinctive substances to obtain images with high resolution. As a result, in the finished protective element material with optically variable properties creates a visual effect, which is due to the dark background still shows up in the form of a pattern with high resolution of its constituent elements.

In another embodiment, it is possible to use conventional printing ink with color gradation from dark to black to obtain a pattern with high resolution, which is complimented by an adjacent pattern, containing distinctive substance. In this case, the layer containing distinctive substance, preferably should be transparent.

In the form shown in Fig.6 valuable document 14 applied protective element 24 in accordance with another variant. This protective element 24 has a magnetic layer 32 containing particles 17 technical carbon. On the specified layer is a translucent layer 15 with optically variable properties, which further comprises the phosphor 18. As such phosphor 18 you can use transparent in the visible region of the spectrum, the phosphor emitting radiation in this visible region upon irradiation with UV radiation.

Beneath the, as well as a visual inspection. Thus, in particular, for visual inspection can be used and the material with optically variable properties, and emission of the phosphor excited by UV light. When automatic control is possible to detect magnetic properties and fluorescent radiation when illuminated by ultraviolet light. Additionally you can analyze the presence of conductivity created by the admixture of carbon black.

In Fig.7 shows a similar embodiment of a protective element 25 according to the invention. In this case, such a protective element also has applied primarily on the valuable document 14 magnetic layer 32 with an admixture of carbon black. Then on the specified layer is applied a layer 19 containing the phosphor emitting radiation in the infrared region of the spectrum. Finally on top of this layer 19 is applied layer 15 with optically variable properties, which is transparent to infrared radiation.

It is shown in Fig.6 and 7 layers does not necessarily have to be located one above the other over the entire area, as shown on the drawings. Thus, in particular, the magnetic layer can be applied in the form of a printed image, as shown in Fig.5. The same is true of the Sabbath.) directly adjoin one another.

In Fig.8 shows another embodiment of the proposed invention in the protective element 26, in which the distinctive substance is applied in the form of code. In this example contains distinctive substance layer deposited on the document 14 in the form of a bar code, which consists of spaced relative to each other sections 30. Intermediate sections 31 are filled with a layer of material that does not contain distinctive substances, but not visually different from sections 30. On top of the layers 30 and 31 is coated with the layer 15 with optically variable properties.

A similar option is the most preferable in cases where the material with optically variable properties is used almost transparent material forming the interference layer, or the liquid crystal material whose color is substantially stands out against a dark background. In this case, the color layer 15 is substantially stands out against the background of the entire zone in which there are areas 30 and 31, the color gradation which changes from dark to black, but distinctive substance is present not in this whole area. At the same time as distinctive substances can be used, for example, a substance absorbing infrared radiation. This substance is of admorim to infrared rays layer.

According to other variant can be provided by only the portions 30, i.e., from the use of sections 31, which creates a masking effect in the visible spectrum, can be waived.

In Fig.9 in the top view shows a special embodiment of the proposed invention in the protective element, which combines the solutions described above with reference to Fig.5 and 8. This protective element 27 has a colour, preferably dark or black, the seal provided in certain areas of the gaps 38 in the form of patterns or alphanumeric characters. Within the seal 36 is additionally provided with a bar code 37, which under normal lighting conditions is visually perceived as the seal 36, and therefore are not visually distinguishable. In Fig.9, however, this bar code 37 for clarity, highlighted by shading than the rest of the hatch seal. Unlike ink, which received the seal 36, the printing ink used to obtain the bar code 37, contains amenable to automatic detection of distinctive substance, preferably a substance absorbing infrared radiation. Printed image consisting of elements 36, 37 and 38, is covered over the entire area of polypr the layer 39 mostly evident on the plot sheets 36 and 37.

The protective element 27 can be produced by various methods. Thus, in particular, prints 36 and 37 can be applied next to each other with exact registration. In other words, if in this scenario, when you run get the impression 36, the plots of the location of the bar code 37 in this run is not sealed to form gaps in the seal 36. On the second run paint containing distinctive substance, printed bar code 37. In another embodiment, the prints 36 and 37 can be applied one on top of another. However, it should be noted that the printing ink imprint 36 should not worsen automatically recognized properties bar code 37.

In accordance with another alternative, both the seal 36 and 37 can include distinctive substances, which differ in their physical properties. It is preferable to apply absorbing infrared radiation substance, the absorption maxima which lie in different spectral regions.

To further complicate the protective element and thereby improve the degree of protection against forgery can be used to obtain a layer with optically variable properties of several materials with optically variable properties, which differ in their physical. the ri on Fig.10 in top view presents only shown in Fig.9 layer 39 with optically variable properties. In this case, the layer 39 is composed of two materials, which differ in their properties. One of these materials with optically variable properties located on the surface 40 and the other at site 41. In this example, the section 41 has the form of alphanumeric characters. However, the sections 40 and 41 may have any contour or shape.

To obtain sections 40 and 41, it is preferable to use liquid crystal materials, which differ in their siteposition properties. Depending on the chemical composition of the liquid crystal material reflects only light of a certain polarization. The chemical composition of liquid crystalline materials you can choose from so that they both are not visually distinguished from one another, but reflect light of different polarization.

When executing shown in Fig.10 sections 40 and 41 with the use of such liquid crystal materials information presented on section 41, it is impossible to recognize when considering in normal conditions. This information becomes recognizable or distinguishable only when Russ.

According to other variant in liquid crystal materials placed in areas 40 and 41, may be added distinctive substance, such as a phosphor. In both the liquid crystal material can be added identical or different distinctive substances, such as two different phosphor or thermochromic substances. You can also use phosphor and thermochromic substances, since the distinguishing substances not necessary to have the same controlled or checked properties. If the protective element must have thermochromic properties of liquid crystal materials can be chosen so that they have different polarization properties and different thermochromic properties.

So, for example, to obtain a plot 40, you can use a liquid crystal material having lesoposadki properties and changes color when exposed to heat coming from the body. However, this material can be added to the first phosphor material is transparent in the visible region of the spectrum. In contrast, section 41 may be covered with prepolarization liquid crystal material, which is also sdcoreservice material at site 40. In the specified second liquid crystal material can also be added to the second phosphor material is transparent in the visible region of the spectrum. Both of these phosphor different wavelengths of radiation. With this approach are contained in sections 40 and 41 of the information, which is not apparent when considered in normal conditions, may become visible, respectively recognizable when using polarizing filters through various siteposition properties of liquid crystalline materials, when heated, due to various thermochromic properties of liquid crystals or the excitation of the luminescence of the phosphors.

With optically variable properties of the layer are described with reference to Fig.10 type can, obviously, be used in all other above options.

Equally shown in Fig.5, 6, 7, 8 and 9, the structure of the printed layers can be provided on the protective strands, respectively, on the bill of material. Such a bill of material can be performed either in the form of film, hot stamping, or in the form of labels.
