The invention relates to a planar protective element for sealing, wrapping, closure and seal documents in order to identify their authenticity.

Due to the constant improvement of quality copiers and computer equipment, you should expect a further increase in the number of counterfeit documents and banknotes. For example, produced using modern copiers counterfeit banknotes impossible just to visually distinguish from the real ones. So you need a special event that cannot be overcome using technology available to poddelyvali today and in the foreseeable future.

Protected document, consisting of a combination of the magnetic paint, visually perceived, at least in the light of signs and, as an additional option for verification of the conductive plating on the entire surface, as described in U.S. patent 5354099 and patent document FRG A. The protection element is mainly composed of strips of transparent film, which has a visually distinct reversible font and which further comprises electrically conductive and magnetic materials.

In U.S. patent 4579371 described by the document containing the coating material having an electric resistance caused by the plots. The coating material consists mostly of the of astora polyacrylic acid in deionized water, glycerin and sodium acetate. Wet layer of material is applied on a polyester film. After heating produces a dry conductive coating with a resistance of 1.2 ohms. Polyester films are used in various weight ratios and (or) other ingredients for other resistances. The main ingredients are sodium acetate, ammonium salicylate, sodium benzoate and / or copper iodide. The disadvantages of this form of surface treatment documents are the complexity of manufacturing and the fact that the coating is not harmless.

Also known metallic coatings applied by printing. Coatings made using metal printing inks, allow a higher resolution depending on the printing method, for example, when dispersed printing. Due to the selection of binders for paints, you can change the local resistivity. The surface glossiness lower than that of surfaces, applied by vacuum deposition. For remedies implemented by metallization with local changes of resistivity with simultaneous maximum possible surface gloss, there is industrially applicable technology, in particular vacuum technology. All of the above-described various what Redstone protection with preventive measures and techniques increasingly large scales possess paddlewheel.

The objective of the invention is that, in addition to overcoming the disadvantages of having a place at the modern level of technology, to offer protection, mainly for sealing, wrapping, closure and seal documents in order to identify their authenticity. Arbitrarily chosen by the manufacturer or his authorised control body and known only to them, the combination of metallic surfaces, sparkle surfaces, electrically conductive surfaces and changes the surface resistance forms an insurmountable for the forger technological obstacles.

At the beginning of the description, let us recall the definitions of terms used throughout the text, as well as all claims. Under incorporation, below, refers to the result of sealing, wrapping, closure and sealing of documents such as passports and identity cards. Under planar metallization means uniformly metallized surface with uniform surface gloss. Under dispersed metallization should be understood inhomogeneous metallic surface, or uniformly metallized surface with detalizirovannymi areas or homogeneous the metallic surface with inhomogeneous surface gloss or uniformly metallized surface with inhomogeneous surface gloss and detalizirovannymi areas. The substrate or carrier substrate is referred to any material on or in which are applied or are being translated means, the material should be understood, for example, a polymer film or a metal foil, laminates, paper, cardboard or cloth. Under coded tool below, in this description and in the claims, refers to a remedy and coding with electrical or optical effect.

The invention planar protective elements constructed from several different components, the coding means and electrically conductive layers, which are connected with the substrate at a different location. Application are known in themselves conducting polymers. A prerequisite for the application of layers of electrically conductive polymers in combination with a metallic layer is a noticeable difference between the specific surface electric resistance (hereinafter referred to as the specific resistance layersin particular, requires a very high surface resistance of the metallized layerWidely used conventional technology does not allow to obtain large values of the inheritance of the resistivity.

As a particularly effective technological obstacles for poddelyvali use applying a layer of electrically conductive polymer, for example polyethylenebutyleneglycoladipinate (PEDT/PSS), in combination with a metallic layer, and the resistivity PEDT/PSS lies within theOn plastic films using primers is achieved resistivityThe polymer layer is applied on a plane or locally, preferably is modulated surface application or application by means of diffuse print. On the basis of locally changing the specific resistance is formed readable code. This in turn provides an easy possibility to detect a variety of ways, in particular by means of capacitive coupling.

A significant benefit is the possibility of a physical machine double checks conductive polymer PEDT/PSS, which on the one hand determined by electrical conductivity, and on the other side of the optical properties, for example in the infrared range. Infrared characteristics can be effectively used with increasing wavelengths (> 900 nm) and depending on the weight of the coating or layer thickness. The absorption and the change in wavelength which may be used as the measured parameters. This double checking will significantly reduce the likelihood that tampering is not detected, i.e. reduce the percentage of unknown fakes, and at the same time reduce the percentage of the true object test, wrongly recognized fake.

The proposed invention is the use of metallic surfaces, particularly those with strong luster, guided by the idea that she has a good electrical conductivity, which may contain conductive remedy or she encoded by changes in conductivity is remedy is an additional obstacle for the forger, so how about the actual appointment, functions and mode of action metallized surface it is impossible to guess, and they are not obvious.

In particular the invention relates to a planar protective element, hereinafter referred to as sealing, mainly for sealing, wrapping, closure and seal documents in order to identify their authenticity authorized control bodies. The seal consists of a substrate of a planar or scattered metalized coatings with a given specific resistance and electrically conductive polymers, also with a given resistivity. According to the invention the resistivity in-plane or Russ is permanent metallized coatings exceeds and the specific resistance of the conductive polymer is in the rangeThe difference between the specific resistance of coatings and conductive polymers exceedsThe invention fittings of this type are connected with documents.

The structure of the injection, i.e. the combination of the substrate, conductive polymers, planar or scattered metalized coatings, protective layers, the separating means and (or) an adhesive layer, is selected depending on the purpose, and the individual layers can be swapped. As release agents are mainly used siliconized layers or transferable tapes or layers. Depending on the destination and applied technology applied primers, and the primers serve as substances that increase the adhesion strength, and according to the invention is suitable for smoothing applied substrates. Electrically conductive polymers, planar or scattered metalized coatings, substrates, and in certain cases also the protective layers and primers are arranged according to the invention as a means of encoding so that their electrical or optical properties are detected through capacitive coupling and, thus, find application in to the availability of funds encoding.

The invention also provides local application of conductive polymers, or coating with surface modulation, or the application locally with surface modulation. Arise in this case, the encoding can also be decrypted by the capacitive method. Similarly, planar or scattered metalized coating applied with the purpose of coding locally, or with surface modulation, or locally with surface modulation can be decrypted capacitive way. As used according to the invention the electrically conductive polymer is preferred polyethyleneoxide-polystyrenesulfonate (PEDT/PSS)

A particular form of the invention is a Union in termination of the individual components. The individual components can, as already described, consist of a substrate, a planar or scattered metalized coatings and conductive polymers, and the individual components can also consist of protective layers, release agents, adhesive layers and primers. The choice and arrangement of the individual layers depends on the intended use and applied processing technology. Different values of specific resistance of the individual layers and in this case lie in the field of the invention. The individual components are the same or different is taenia form code combination by themselves or after their integration into the capsule. If the code combination is formed only after the connection of the individual components, the accuracy of alignment is essential.

Hereinafter the invention will be further described and explained with the help shown in the drawings of examples of implementation. In the drawings shown:

Section one of the proposed invention fittings 1 schematically presented in figure 1A. It consists mainly of a substrate 10, a planar or scattered metalized coating 13 and the electrically conductive polymer 12 with a resistivity of the order ofmoreover, the difference between the resistivity in-plane or scattered metalized coating 13 and the specific resistance of the electrically conductive polymer 12 exceedsLayers can be interchanged. On fig.1b shows the substrate 10 with a planar metallic coating 13, the resistivity of which exceedsnot detectable by the human eye conductive floor which measures 12 - polyethyleneoxide-polystyrenesulfonate represents the identification number and the protective marking.

Example 2:

On figa shows another variant of the seal 1. The substrate 10 ironed primer 11. It is electrically conductive polymer 12, which in turn, if necessary, may be provided with a primer 11. Then metallized layer 13 and, if it is desirable to use conditions, the final protective layer 14, and between the metallic layer 13 and a protective layer 14 again, you may need primer 11. The protective layer 14 may be coated to improve the appearance of colored lacquer, not shown in figure 2A. There is also a variant in which the protective layer 14 consists of such a varnish. A layer of electrically conductive polymer 12 and the metallized layer 13 can be swapped. Used primers 11 can also act as substances that increase the adhesion strength. Additionally, sealing 1 contains an adhesive layer 15 for connection with the documents. If the documents are entered in the embedding 1, for example, if the documents are sealed, pressed or sealed in a wrapper made of film, the adhesive layer 15 can be waived. As sealing 1 normally wound on the roller, it is recommended that one side of it to cover the separation layer 9, preferably silicon film. As the separation with the HHS 9 seal 1 can be equipped also transferable tape 16 (figs), equipped with a means of combining 8, for example, perforations, magnetic paths or optical markings for exact positioning of the fitting 1 on the document. Another variant of the seal shown in Figi. The substrate 10 is covered with layers on both sides, and conductive polymer 12 is located on one side of the substrate 10 and the metallized layer 13 on the other.

Depending on the intended further use and technological capabilities of the basic layers of components 30; 31 can be changed between a and to connect the components 30; 31 in different places.

Example 3:

In another embodiment, sealing 1 or one of the partial components 30; 31 electrically conductive polymer 12 is applied to the modulation on the surface. Figa schematically explains the structure of the plot seal 1 or one of the components 30; 31. By changing the thickness of the layer and changing sledstvieto resistivity occurs coding. In this example, the execution of specific encoding produces a modulated specific resistance (FISA).

Example 4:

This example illustrates the incorporation of 1 or component 30; 31 similar to that described in example 3, and the electrically conductive polymer 12 is applied locally. As can be seen from fig.3b, local application of polymer 12 plots leads to local changes of resistivity, which in turn serves as the encoding.

Example 5:

On figs shown another form of seal 1 or component 30; 31, representing a combination of options from examples 3 and 4. Electrically conductive polymer 12 is applied locally and polymer layers in these areas modulated surface. Locally changing as a result of specific resistance form encoding by manufacturer and date of manufacture, and areas modulated by the surface form encoding.

Example 6:

In accordance with this example of execution serves one or more encodings, combined as in examples 3, 4 and / or 5, and they are implemented in various directions in the plane. So, for example, electrically conductive polymer 12 in one direction on the plane is applied locally with surface modulation, as in example 5, and in the other direction on the plane locally, as in example 4, in both directions oznikaet different encodings.

Example 7:

The next version of seal 1 or component 30; 31 primer 11 is applied locally, or with surface modulation, or locally with surface modulation, as shown in examples 3-6 for conducting polymer. The resulting structure of the primer is transmitted as the carrier structure, the applied layer of the electrically conductive polymer 12 and (or) the metallized layer 13. Arise encoding, as described in examples 4-6.
