The invention relates to tamper-resistant paper for the manufacture of valuable documents, such as banknotes, certificates and other similar financial documents, having at least one multi-layer protective element, allowing you to create at least one amenable to visual inspection optical effect, such a protective element at least partially located on the surface is protected from a fake paper. The invention relates also to a multilayer protective element and valuable document with such a protective element. The invention relates further to a bill of material intended for transferring multi-layer protective element on the valuable document, and to a method of manufacturing such a bill of material, respectively valuable document.

At the present time, there is still an urgent need to increase the level of protection securities against counterfeiting and unauthorized reproduction. It is based on a continuous improvement of copying and printing equipment is complicated by the search for new, effective security features, which would, if not completely prevent unauthorized reproduction, respectively, of securities fraud, at least to ensure reliable detection of such tampering.

From the publications the WO 96/01458 known conversion material, designed to move multilayer protective element on a valuable document and having the layer-substrate, on which, with the possibility of separation from her prepare the layered structure of the protective element, allowing you to create at least one amenable to visual inspection optical effect, and a method of manufacturing such a bill of material and valuable document with its use. Using known from WO 96/01458 transferable material on the valuable document is transferred a protective element made in the form of a hologram. This hologram contains a diffraction grating (i.e. a kind of microrelief)disposed between the transparent and adhesive layer. The transfer of the protective element on the valuable document carried out by the method of hot stamping, i.e. by affecting the protective element high pressure and high temperature. Obviously, this method is unsuitable if the protective element is used integrated circuit.

In the publication EP 0019191 B1 were asked to provide a security integrated circuit recorded in her memory controlled code, communication with this integrated circuit is preferably a contactless way by means of the antenna. Such integrated circuit in the recess is made at least partially metallize vannoy film substrate. This film, the substrate is then placed between two paper tapes, repressively to it. However, when placing the film substrate in such a laminate only between two paper tapes forming a multilayer structure of layers it is easy to separate from one another, thus having access to the laminated between two paper tapes and provided with a chip intermediate layer, which subsequently can be used to manufacture fakes. In addition, this protective element is a protective element, yielding exceptional machine control only by means of special detectors.

As signs of authenticity, which are quite easy to check visually and which are sufficiently distinct to the surrounding background, often use protective elements with optically variable properties of the type, for example, holograms, which are at different angles to create different optical effects, for example, change color or reproduce some information. Equipped with such a protective element of security known from EP 0440045 A2. This publication describes the banknote is carried out by type of hologram labels. Since the optically variable effect produced by the hologram cannot be reproduced using a color copy the oval device, such protective elements provide adequate protection from a color copy. However, the disadvantage of such protective elements is that they are extremely difficult to verify by engine control, because for reliable recognition of a certain hologram to detect radiation reflected diffraction structures of the hologram under certain bodily corners, and you virtually eliminate the influence of scattered radiation. Another problem associated with the variability of signal intensity, because it largely depends on the source of the illumination of the hologram. Therefore, to obtain when measuring accurate results are required to provide specific conditions of illumination of the hologram.

To solve this problem have been proposed to superimpose one on another visually distinct hologram and permeable to laser hologram, designed exclusively for machine reading (DE 3840037 C2). Reading such machine-readable hologram can only be done with a laser, while hidden in such permeable for the laser irradiation of the hologram information is projected on a certain button before valuable document area of space, coord. what you set during recording of the hologram. For recognition capabilities such hidden information in this region of space must be appropriate detector. However, this type of protect valuable documents from forgery, allowing for visual and machine control, is associated with significant costs both at the stage of their production, and at the stage of validation.

Based on the foregoing, the present invention was used to develop a valuable document, adequately protected from counterfeit paper with a protective element, which would allow to create amenable to visual inspection optical effect and at the same time made him the machine control, such is protected from a fake paper and valuable document should be simple and inexpensive to manufacture.

To solve this problem is proposed protected from a fake paper for the manufacture of valuable documents, such as banknotes, certificates and other similar financial instruments, or in fact such a valuable document. As in the decision-analogues, such as paper or valuable document is provided at least one multi-layer protective element, allowing you to create at least one amenable to visual inspection optical effect, and the protective element at least partially located on the surface is protected from the delky paper and provided with at least one integrated circuit.

In the context of the present invention the term "tamper-resistant paper" means unsealed, that is not equipped with a printing prints on paper, which in addition to the proposed invention, the protective element may have other signs of authenticity, such as those present in the volume of the material phosphors, security thread, or other protective elements. Typically such a paper presented in the form as if an endless belt or fabric, i.e. not yet cut into individual sheets, and is intended for further processing. The term "valuable document" means the document prepared for the intended purpose of use. It can be, for example, sealed securities, such as a banknote, certificate or other similar document, identity card, passport or other document that must be protected from tampering.

In one embodiment, the solution of the problem behind the invention is achieved in that the protective element has at least one layer containing pigments with optically variable properties, primarily interference or liquid-crystal pigments. In another embodiment, the solution to the above problem is achieved in that the protective element is at least one of Metallichesky and one dielectric layer and at least two dielectric layers with different refractive indices, these layers in their interaction create in reflected light under different angles of view of different visually perceptible visual impression.

In the subsequent description of the proposed invention the solution is illustrated on the example of tamper-resistant paper. However, all of the following advantages and embodiments of the invention apply equally to securities documents.

Another object of the invention is a multilayer protective element intended for application to a valuable document and allows you to create at least one amenable to visual inspection optical effect, and also provided with at least one integrated circuit. In one embodiment, the invention proposed protective element has at least one layer containing pigments with optically variable properties, primarily interference or liquid-crystal pigments. In another embodiment of the invention offer the protective element is at least one metal and one dielectric layer and at least two dielectric layers with different refractive indices, with these layers in their interaction create in reflected light under different angles of view of different visually perceptible visual impression.

Pouch the multilayer protective element on a valuable document provided by the use of transferable material, which is also an object of the present invention and having a layer-substrate, on which, with the possibility of separation from her prepared layered structure of the protective element, allowing you to create at least one amenable to visual inspection optical effect. Unlike solutions WO 96/01458 the invention makes it possible inclusion in a layered structure of the protective element is at least one integrated circuit.

The object of the invention is also a method of making a valuable document with a protective element, in the exercise of which the separate parts of the valuable document is transferred layered structure of the translated material, and then remove the layer-substrate. In accordance with the invention is proposed as a bill of material to use bill of material of the above-described structure.

As described above, according to the invention is protected from a fake paper supply at least one multi-layer protective element that allows you to create visually distinct optical effect, which with the help of copy technics cannot be played at all, or you can play only in a distorted form. Such a protective element at least partially located on the surface is protected from a fake paper, and in one of its inner layers provided on less is th least one integrated circuit. Such integrated circuit may constitute, for example, crystal persistent storage (permanent storage, or abbreviated as ROM), crystal rewritable memory (EPROM or EEPROM), or a microprocessor chip. The thickness of the crystal (chip) is from 5 to 50 μm, preferably 10 μm, and the length of one of the parties is from about 0.1 to 3 mm, preferably 0.6 mm Such a crystal preferably has from two to four pads.

Created a protective element optical effect may be due to the presence of this protective element layer containing pigments with optically variable properties, primarily interference or liquid-crystal pigments. Such a layer can be either solid or have certain contours, reproducing some information. In another embodiment, the protective element may be a hologram, Kinegram or other diffractive structure. Such diffraction patterns preferably in the form of a relief structure obtained in the polymer layer by embossing. Since the diffraction patterns should be visible in reflected light, combined with a reflective layer, first metal layer or the dielectric layer with a high refractive index. When this reflected the Mering layer need not be continuous, and can be made in the form of raster or it can be given any arbitrary contour reproducing some information. In this reflective layer can be provided, in particular, white space areas in the form of designs, patterns, alphanumeric characters or symbols. Another possibility of creating amenable to visual inspection optical effect is to use thin-film structures comprising placed one on top of another metal and/or dielectric layers with different refractive indices, such layers in their interaction create in reflected light under different angles of view of different visually perceptible visual experience. It is preferably about changing their color from different angles of view.

In another embodiment, to create the above optical effect, you can use any printed image (impression) or a metal layer with white-space plots (cutouts) in the form of patterns, alphanumeric characters, symbols or other elements. And most a metal layer can be shaped contour in the form of alphanumeric characters, symbols, or patterns. You can also use special printing inks, for example fluorescent printing inks. Obviously, that can also be used with several which produces a certain optical effect of protective signs. Under referred to in the subsequent description "creates an optical effect layer" includes interacting multi-layer structure type, for example, the above dielectric thin-film structures, or a combination of several layers, creating different optical effects. Similarly, the term "hologram" is a collective designation of any diffractive structures.

Proposed in the invention of the integrated circuit is preferably located between the above creates the optical effect layer and counterfeit paper. This placement of this integrated circuit can protect it from external influences and to make it virtually indistinguishable visually. It is preferable to use integrated circuits, communication, i.e. communication that is performed by contactless via the coupling element. This coupling element or may be an already integrated in an integrated circuit component, or may be located separately from her in one of the layers of the protective element. The advantage associated with the integration of the coupling element in a layered structure of the protective element, is that an integrated circuit in the attempt of illegal manipulation with it or try to make her use a fake impossible the Department shall be without damage or malfunction from prefabricated original protective element, respectively provided with such a protective element of the valuable document for the purpose of its occupancy, for example, on a fake reproduction of the valuable document. However, this coupling element may be made in the form of a loop of the vibrator coil or dipole with not interconnected shoulders. To improve the efficiency of the entire system in a loop the vibrator or the coil can also be provided with the function of the metallic core area. When running coupling element inside creating an optical effect layer this performs the function of a solid core zone also reduces the undesirable effect of the relationship on the overall visual impression created by the specified layer. Depending on the type of coupling element and the selected frequency at which the data is read from the integrated circuit and the write data, and which is, for example, 13.56 MHz and 2 GHz, the range of coupling element may be from 0.1 mm to several centimeters.

Proposed in the invention, the protective element is preferably applied to protect against forgery paper after it was made, and connect it so that it could not again be removed from this paper without damaging it, respectively, without damage to the protective element. In choosing the accordance with this advantage of the invention lies in the fact, that, on the one hand, the process of applying a protective element to protect against forgery paper you do not want to integrate in the process of its production, and on the other hand, provides the necessary protection against forgery a compound of the protective element with the security. Another advantage of the invention is that the protective element has several levels of protection against forgery. Thus, in particular, created facing the observer layers of protective element optical effect cannot be reproduced identically to the original using copiers and other reproduction techniques that can easily and quickly detect such tampering even when visual control.

If you try to forge valuable document, respectively, the protective element will still be able to play or simulate created a protective element optical effect, a fake in any case it will be possible to detect when the engine control by checking the integrated circuit. Since this integrated circuit is placed inside a protective element and covered with creating an optical effect layer, a potential falsifier simply will not be able to recognize the presence of this additional sign of authenticity and therefore do not even try to imitate it.

Proposed in the invention protective the element preferably in the form of a self-supporting multilayer labels or bill of an item, put on protect from forgery paper and connect it after it was made. While the protective element can be given any arbitrary contour. In another embodiment, the protective element can also be performed in the form of a security thread. In this case, the integrated circuit and creates an optical effect layer is placed on filamentous or having the form of a narrow strip of a polymeric substrate, which in the manufacture of paper buried in the material of the paper web in the form of so-called diving thread, which in some areas goes directly to the surface is protected from a fake paper. According to one preferred options this security thread has two polymeric substrate, between which are enclosed integrated circuit and creates an optical effect layer.

Under "transfer element" in the context of the present invention refers to a protective element, which pre-manufactured or prepared on a separate substrate, such as a polymer film, with its layers in the reverse sequence in which they will later have to be on tamper-resistant paper, and then using adhesive or lacquer layer is transferred to give the desired contour to be protected from a fake paper. Such a substrate after transferring the layered structure protect the private element on paper, you can either delete or save this layered structure as its protective layer, constituting an integral part of the protective element.

On the common substrate can also pre-make several individual transferable elements to give each of them needed to transfer to the substrate, i.e. protected from a fake paper path. In another embodiment, the substrate can be performed continuously layered structure without its division into individual transferable elements. Substrates of this type located them at certain intervals of individual transferable elements or continuous layered structure in the following referred to as "bills of material ", and located on a substrate or layer on the substrate a sequence of layers that make up the actual protective element, called the "transfer layer".

When using continuous conversion conversion layer material are combined in the following with protected from a fake by a paper with a layer of adhesive, which is activated using the appropriate tools or dies for stamping, resulting in this conversion layer is glued to the protected from a fake paper only in those areas where activated adhesive. With all the other sites conversion material is then removed together with the layer-substrate. Another is the Rianta adhesive layer also can be shaped contour, the appropriate form may be transferred paper protective element. As an adhesive while it is preferable to use a hot-melt adhesive. However, for the same purpose you can use or any other adhesives, such as reactive lacquers.

In another embodiment, the protective element can also directly apply to the valuable document. In this case, all of the above is true in relation considered in relation to counterfeit paper embodiments of the protective element and its connection with the base.

Following the example of bill of material examined in more detail some preferred embodiments of the layered structure proposed in the invention, the protective element. In this case, as is obvious, a similar layered structure, respectively, but only with reverse sequence of layers can be used for making labels and protective threads.

In the simplest case, a bill of material consists of a substrate layer, which preferably is transparent polymer film, and at least one creates the optical effect layer and at least one integrated circuit. In this embodiment, in the composition of the integrated circuit also includes the element of communication with the reader/write data.

When using the integration of the General scheme, without integrated coupling element, the corresponding element of communication must be provided in a layered structure of transferable layer of transferable material. Such conversion layer with an integrated coupling element thus preferably in the form of a thin, nesamoney film. Due to this it is possible to prevent the attempts to forge valuable document, the purpose of which is the separation made in the factory original protective element is protected from a fake paper, because nesamoney protective element cannot be removed from the base without damaging it.

As mentioned above, the coupling element may be made in the form of a dipole with not interconnected shoulders, loop vibrator or coil. Such a coupling element is preferably done by demetallization of the metal layer on the respective sections. To this end, the layer-substrate bill of material, which is optionally provided with a separating layer, a first cause which creates the optical effect layer. Then on top of this layer on its demetalizarea in subsequent sections of the printing applied water-soluble or soluble in a different solvent layer of printing ink. At the next stage on the entire surface of the substrate with the her hand, with which location is this napechatanny layer, applied metal coating. Then at the final stage to remove soluble printing ink, as well as being on the same parts of the material of the metal layer. On top of this metal layer and then using a layer of conductive adhesive, such as electrical silver or anisotropic conductive adhesive, fix integrated circuit. After that, at least in some parts of the substrate layer is applied the adhesive layer.

In another embodiment, to give a metal layer of a desired contour, i.e. to remove material on certain sites, you can also known etching methods. In this case, the entire surface of the substrate layer after application it creates the optical effect layer applied directly to a solid metal floor. After that, a metal layer is sealed with a layer of protective lacquer, giving it a contour corresponding to the desired shape of the coupling element. Then, not varnished areas with appropriate solvents to remove the material of the metal layer. The protective layer can also perform a phototechnical method of coating metal layer is a continuous layer of photoresist followed by exposure and manifestation.

According to another variant of the forming element connection metal layer can be separated from condosespecially effect layer by an insulating layer. The presence of such insulating layer is necessary in that case as part creates the optical effect layer is a conductive layer.

In accordance with the following variant of execution of the invention the metal layer can also be used directly to create a visually distinct optical effect. For example, when using a reflective hologram creates the optical effect layer usually consists of a layer of varnish, which is embossed in the form of a relief structure is embossed diffraction patterns of the hologram, and the metal layer. When this layer is the substrate of the translated material is first covered with a layer of varnish, which is then embossed push diffraction patterns. Then on top of this layer of varnish applied metal layer. However, before applying the metal layer, which is preferable to carry out the vacuum deposition method (method of coating by vapor phase deposition), on the layer of varnish, as mentioned above, printing is applied soluble paint required for the formation of the coupling element. After application of the metal layer soluble paint is removed and the top metal layer, which is also mentioned above, is placed integrated circuit. In this case, to give a metal layer of the required contour is also possible and the user already discussed above etching methods as an alternative to applying soluble printing ink.

In this embodiment, the coupling element is visible in the case when the embossed lacquer layer, which in the finished protective element forms an outer facing the observer layer is transparent. Because this effect is undesirable, embossed lacquer layer can be given a specific color. To this end it is preferable to use metallic pigments. In another embodiment, the protective element, respectively, is protected from a fake paper serves to laminate the film or to provide a seal that allows you to "mask" the element of communication, making it invisible.

An additional advantage of this option is that providing for the establishment of a specific optical effect of the layers of the protective element narashima connected with the verified by engine control integrated circuit. Any unauthorized manipulation creates the optical effect layers simultaneously reflected on machinescasino module.

However, the coupling element need not necessarily be formed of a metal layer, which give the appropriate path. This connection element can also be formed by a layer of conductive polymer, which, for example, is applied by printing to give it the appropriate path.

In all embodiments, the connection between the coupling element and the crystal (mi what roshanai) via the conductive connecting structure, such as conductive adhesives, solder, etc. or contactless, for example capacitive, by.

To prevent extraction of the integrated circuit together with the coupling element by cutting of the protective element, respectively provided they are protected from a fake paper education in their place not visible to the naked eye holes of the coupling element preferably larger. If the holding element connection area is 20 mm or more, in this case, the communication becomes impossible to remove by cutting of the protective element, respectively provided they are protected from a fake paper without education it is quite large punched holes, which would be visually distinguishable even to nonspecialists.

Then from the offer provided in the invention, the protective element is protected from a fake paper can produce any valuable document. In the manufacture of such tamper-resistant paper, for example, banknotes it is usually cut into sheets of a certain format with multiple units using its area, which subsequently processed on the respective printing machines. In addition, each unit using a square sheet has at least one proposed in the invention protective the element is provided. In one of the preferred options, the protective element is designed in the form of strips running parallel to one edge of the unit use the square sheet. A related advantage is the possibility of moving the protective element to protect against forgery paper in a continuous mode.

Obtained in the process of printing the print may also at least partially superimposed on the plot of the protective element, making it possible to further increase the degree of protection of the valuable document from forgery and especially when using to get such superimposed on the protective element of the print method print with steel engravings, allowing to obtain distinguishable by touch prints. However, the proposed invention is protected from a fake paper can also be used for the manufacture of other valuable documents such as passports, stocks, visas, identity cards in the form of maps, certificates, tickets to various cultural events, accompanying documents for the carriage of goods, security labels, checks, etc. Such valuable documents, in turn, can be placed as to indicate the authenticity of the product items on products of any kind, such as CDs, perfume products, pharmaceutical products, packaging and all types etc.

The degree of protection offered in the invention is a valuable document from forgery could be further enhanced, preserved in the integrated circuit defined specific valuable document information with the possibility of its control. For example, in integrated circuit can store data describing the history of the relevant securities document. In the case of banknotes in the integrated circuit can be saved, for example, information about the date of their issue and their subsequent presence in the circulation, which allows thus to analyze the chronology of the banknotes that has until now been almost impossible. Similarly in the integrated circuit can maintain the information about the suitability, respectively unfitness of banknotes for further treatment.

In addition there is the possibility to mark valuable documents as permitted for use for certain purposes, respectively, to block their use for specific purposes. Associated with this particular advantage consists in the possibility to provide such a marking banknotes sent extortionists as ransom, and keep track of their further circulation.

According to a special variant of the invention, the integrated circuit protective element can additionally be equipped with a light-sensitive element is m or connect with him, which is also placed in the material is protected from a fake paper, respectively, of the protective element and which reacts, for example, to get to light, temperature changes, changes in the magnetic field or other parameters. Measured in such a sensitive elements the results are transmitted to an integrated circuit and stored in it. This way you can, for example, to register each copy of the document by the fall of light of high intensity and save in the integrated circuit information on the number of individual processes copy of the document. A related advantage is the possibility of differentiated manufactured with document copies on legal and illegal. During a legal copy of the document the user has information about the presence of counterfeit paper corresponding sensing element and after copying of the document using only a special device can again be removed from the memory integrated circuit with information on legal reproduction of the original document. Information about illegal reproduction of the valuable document is not erased from the integrated circuit. Check before each copying process corresponding to the memory integrated circuits in the presence of data records previous processes is operamania allows you to prevent further illegal copying valuable document. This approach is preferable to use primarily in relation to documents that are typically stored in a closed, light-tight space.

In another embodiment, in the memory of the integrated circuit can also save the information about the identification numbers of individual copiers. If there is an opportunity to identify further on, all used for making copies of a particular valuable document copiers. This ability allows you to identify the attackers, carrying out illegal copying valuable document. Besides themselves and the copy device can be equipped with a corresponding reading devices that detect the corresponding label in the process of reading data from the memory integrated circuit block up valuable document.

An integrated circuit can also be used to store some kind of "e-print" issued a valuable document of authority. This ability is preferably used when issuing visas or passports. In memory integrated circuit of each of the valuable document, it is advisable to retain some personal information. Such information may consist in the simplest case, the set of random numbers or more complex Yes, the ones, which may contain information about the characteristics of specific valuable document, for example about the deviation of the impression from the nominal within a specified tolerance, the light transmission properties of the paper or other document. Such information also may be stored in a cryptographically encrypted.

In addition to this integrated circuit can also be used for duplicating printed on the value document readable information with the purpose of protecting it from tampering. For example, if a valuable document some identifying information, such as its serial number and data about the Issuer, the relevant information in electronic form can be saved in the integrated circuit. Such information is preferably stored in an encrypted form, access to which, accordingly to that can only be decrypted using the corresponding key. In the authentication process valuable document stored in its integrated circuit information is compared with the actually present on the document readable information.

Contactless communication with the IC scheme allows to some extent to facilitate the handling of such documents and their review conducted, for example, by delivery of the goods when crossing the state the state borders and in all other cases, associated with tracking the flow of goods along with their relevant documents, to ensure a virtually continuous control. So, for example, proposed in the invention, the solution allows you to identify the carrying out smuggling operations.

When using a microprocessor as an integrated circuit, which is equipped with tamper-resistant paper, respectively, which provided a valuable document, it can be used for based on the use of appropriate cryptographic methods to generate encrypted data and its transmission to the device read/write data. In addition, in such a microprocessor can be used, and any other programs or multi-functional configuration. This may be already known for their application in engineering data respectively associated with the use of chip card technology methods and technologies.

Other embodiments of the invention and its advantages are discussed below with reference to the accompanying drawings. It should be noted that these drawings are for illustration purposes only and are made not to scale. While in the drawings, in particular, shows:

figure 1 - proposed in the invention is a valuable document

figure 2-5 - different ways to perform predlagaemoj is in the invention of the translated material in the section and

on figa-6D - various embodiments of the proposed invention the coupling element.

Figure 1 in the form of the plan performed on one of the options proposed in the invention is a valuable document. In this case, this valuable document is a banknote 1 made of the proposed invention is protected from a fake paper. This bill has proposed in the invention, the protective element 2, made in the form of transferable element and printed on the bill using the bill of material, described in more detail below. Note 1 may have an additional protective elements such as the security thread 3. Such a security thread 3 in the form of so-called windowed security threads like "woven" into the material of the paper and in some areas 4 reaches the surface of the banknote.

Figure 2-5 shows various embodiments of the proposed invention transferable material 10. The main components of such a bill of material 10 are layer-substrate 5, and a transferable layer 6, at least individual sections which are transferred to the proposed invention is a valuable document. In the case shown in figure 1 of the protection element 2 conversion layer 6, are transferred to the bill of his separation from the substrate layer 5 has, for example, the shape of a square. At this layer, the substrate 5 may have angelically layer, contributing to the separation from her transferable layer. This separation layer not shown. It is obvious that the contour of the transferable layer can be shaped in any other form until extremely small ("filigree") structures such as, for example, gelosa or similar structures. The protective elements 2 often perform as well in the form of strips parallel to the protective thread 3.

Shown in figure 2 conversion layer 6 consists of creating a specific optical effect layer 7, the integrated circuit 8 and the adhesive layer 9. As integrated circuit 8 are already equipped with integrated coupling element, in a layered structure of a translation layer 6 is not provided additional layers for communication with the integrated circuit. With this in mind, creating an optical effect layer 7 can be arbitrary. More preferably, however, to perform this layer at least on the plot of the integrated circuit 8 is opaque, which allows you to hide an integrated circuit 8, making it invisible.

In the form shown in the drawing option creates the optical effect layer 7 is made of a solid, i.e. occupies a total area of transferable layer, and in turn may consist of several layers. For example, the layer 7 may be made in the form of thin-film element, which consists of several dielectric layer is, distinguished by their indices of refraction, and a thin metal layers. Created similar to the layered structure of the optical effect is the overflow of colors, i.e. change color depending on angle of view.

The layer 7 may be made and any other create a specific optical effect layer, for example in the form of a printed layer containing pigments coated with optically variable properties and creating in accordance with this optically variable effect. To this end it is preferable to use liquid crystal pigments or other pigments, which uses the interference effect, such as pigment IRIODINE®firm Merck.

The adhesive layer 9 is used for attaching the protective element 2 on the surface of the valuable document. At the same time as the adhesive forming such a layer, it is preferable to use a hot-melt adhesive, a heat-activated under the influence of stamps for hot embossing with a corresponding shape of the working surface. The adhesive layer 9, as it is obvious, can also be envisaged only in some areas, allowing you to properly set the path being transferred to a valuable document conversion elements still in the bill of material. According to another variant bill of material shall also be performed even without the adhesive layer. In this case, the adhesive layer is applied to give it the necessary contour directly on the very Foundation on which you want to migrate conversion element.

The shown in figure 3 bill of material entering into its structure integrated circuit has an integrated element of communication. For this reason, the conversion layer 6 in addition to solid, occupying the whole of its area creates the optical effect layer 7 has a metal layer 11. In the shown figa embodiment, this metal layer 11 made in the form of a loop of the vibrator and forms the element of communication with the integrated circuit 8. The connection between terminals or contacts of such a loop vibrator formed of a metal layer 11, and the contact pads of the integrated circuit is provided with a layer of conductive adhesive 12.

Shown in figure 4 conversion layer 6 provided with a hologram formed by embossed or imprinted layer 13 and the metal layer 14. Thanks to the metal layer 14 is boldly embossed diffraction patterns of the hologram is visible in reflected light. It is obvious that the metal layer 14 is not solid, but with gaps 19. Giving such gap 19 defined in the plan form allows to obtain a formed metal layer element 11 communication with the integrated circuit 8. Similarly, shown in figure 3 variant such the element is provided a communication loop formed by the vibrator, which space 19 is separated, respectively, isolated from the rest of the metal layer 14.

In this example, the metal layer 14 is also part of creating an optical effect layer 7, and a functional component of the integrated circuit 8. Obviously, if the embossed layer 13 is transparent, the element 11 due readable visually, if you look at the valuable document from the top. If this effect is undesirable, the embossed layer 13 can give a certain color to use in his composition of translucent paint. You can also use dielectric having metal luster pigments to make the connection element 11 are not visually distinguishable or at least make it less noticeable.

Shown in figure 5 conversion layer 6 is also provided with a hologram, which combined with the integrated circuit. In this case, the reflecting layer 14 of the diffraction patterns does not form at the same time the element of communication with the integrated circuit 8. Moreover, this metal layer 14 is separated from the forming element 11 connection of the metal layer 17 and the insulating layer 15. However, this metal layer 14 has a notch or space stations 16 in the form of alphanumeric characters or symbols or drawings that clearly visible and readable at least question is no. Such space stations form one more amenable to visual inspection a sign of authenticity.

The structure forming the connection element 11 of the metal layer 17 is similar to the structure shown in figure 4 reflecting layer 14. In other words, in this metal layer 17 are the gaps 19 between the connection element 11 from the rest of the material of this metal layer.
