The invention relates to the technology of paper, polymer structures, protective elements used for protection against forgery of documents, securities, printed materials and other products.

Widely known used for protection against forgery and counterfeit manufacturing protective elements in the form of a thin-layer magnetic structures (EN 2296678 C2, 10.04.2007). Known technical solutions protective elements, allowing both visual (EN 2299427 C2, 20.05.2007)and instrument control (EN 2326436 C1, 10.06.2008).

Closest to the proposed technical solution is the solution described in patent RU 2326436 C1, 10.06.2008, where it is proposed to use as a protective element to use security thread containing in its structure a thin magnetic layer. During the registration and authentication of the protective element is a fixing apparatus of a magnetic field scattering from different parts of the protective thread. The disadvantage of this solution is the possibility of registration failure due to uncontrolled movements of the banknote as it moves relative to the magnetic heads recording systems.

The problem solved by the invention and the technical result - the creation of a protective element, resistant to mechanical, chemical and thermal resistance and stability Prov is Denia identification.

This is achieved in that the protective element for valuable document in the form of a multilayer polymer structure with a magnetic layer containing hidden information, identifiable electromagnetic devices, characterized in that it includes an external transparent polymer base with attached to it a transparent lacquer layer, the surface of which is made of the skin coated with thin layers of reflective and magnetic materials to which the adhesive layer attached to the outer transparent lamination layer, and the depth of surface is 0.01 to 0.5 μm.

Additionally, the result is achieved that the microrelief is a periodic or quasi-periodic bandpass reliefs.

Protective element for valuable document may further comprise a transparent protective destructible layer located between the outer transparent polymer base and lacquer layer.

The microrelief can be performed by the method of embossing, thin layers of reflective and magnetic materials can be deposited on the skin by vacuum deposition, as the reflective material may include a soft magnetic metal, which serves as a reflective and magnetic layer.

Protective element for valuable document may contain two or more layers magni the aqueous material, moreover, the latent information contained in each magnetic layer differs from the latent information contained in the other magnetic layers.

The result also ensured product, provided with a protective element made as described above.

The invention consists in that the protective element for valuable document in the form of a multilayer polymer structure with a magnetic layer containing hidden information, identifiable electromagnetic devices according to the invention, contains an outer transparent polymer base with attached to it a transparent lacquer layer, the surface of which is made of the skin coated with thin layers of reflective and magnetic materials to which the adhesive layer attached to the outer transparent lamination layer, and the depth of surface is 0.01 μm to 0.5 μm.

In particular, the microrelief may be a system of periodically spaced magnetic strips (grids) with a spatial period of from 0.1 μm to 100 μm. The protective element may further comprise a transparent protective destructible layer located between the outer transparent polymer base and a lacquer layer. The microrelief can be performed by the method of embossing, and thin layers of reflective and magnetic materials deposited on the microrelief metadatachanged spraying.

In the particular case of the protective element as the reflective material may include a layer of soft magnetic metal, which serves as a reflective and magnetic layer. The protective element, in particular, may contain two or more layers of magnetic material, and the latent information contained in each magnetic layer differs from the latent information contained in the other magnetic layers.

The figure 1 shows the cross-section of the protective element on the periodic basis (lattice) of elevation.

The claimed technical solution is proposed to change the magnetic characteristics of the magnetic layer by creating a magnetic film of micro - and nanoscale topography. Depending on the configuration of the elevation change of the magnetic characteristics of the magnetic film. Namely, formed local changes of in-plane magnetic anisotropy. These changes are recorded electromagnetic apparatus, the analyzing field of the magnetization reversal of the magnetic film. Registration can be performed remotely at distances up to tens of centimeters. The present apparatus allows to distinguish more than ten different configurations of terrain that can provide entry to 210information States. Created micro - and nanorelief difficult waspressed what we not visually recognizable and are within the protective elements. When trying delamination of protective elements to copy the structure of the relief, the magnetic layers are destroyed and the copying is not possible.

During the operation of the protective elements of the proposed type resistant to mechanical, chemical and thermal influences, which provides stability and reproducibility when performing operations on the identification and recognition of such protective elements.

The technology of forming the proposed reliefs based on the process of embossing and is suitable for mass production equipment for manufacturing a prismatic (flat relief-phase) holograms and nanograms.

An example of the performance of the proposed technical solutions can serve as a protective element on the basis of thin-layer flat relief-phase periodic or quasi-periodic bandpass relief patterns (figure 1). On a transparent polyethylene terephthalate (PET) film 1 is formed of a transparent polymer layers. Transparent layer 2 serves to ensure the destruction of the protective element when attempting to separate it from the protected product (in some cases, this layer may be absent). In a transparent polymer (lacquer) layer 3 method embossing (hot stamping, molding) is periodic activities the ski or quasi-periodic relief. For control of quasiperiodic relief is possible to visualize such reliefs optical methods from the side of the PET film, for example, through observation of diffractive (holographic) pattern in the reflected light due to the spatial phase modulation of light passing through the layer 3 and reflected on its borders. To increase the brightness on the polymer layer 3 by vacuum deposition thin reflecting layer 4 of a metal with high reflectance. This can be a layer of aluminum, silver or copper. Write periodic structures produced in the layers 1-2-3-4 method embossing. After recording the images of the duplicate structure (laminate) the second PET film 5 or paper-based. Between layers 4 and 5 is the adhesive layer 6 of polymer interlayer adhesive compositions. Magnetic bump layer is introduced into the structure by vacuum deposition on the layer 4 thin (10 nm - 100 nm) layer 7 of magnetic material (for example, Nickel or permalloy). Can also be used as the reflecting layer 4 layer of a magnetic metal, such as Nickel. In this case, the coating layer 7 is not required, the layer 4 itself is magnetic. Periodic patterns formed in the layer 3, also formed in the magnetic layer 7 or, respectively, in the magnetic layer 4 to the latest version. Relief magnetic layer them is no pronounced magnetic anisotropy, the orientation of which is determined by the orientation of the strokes periodic relief in the magnetic film. Using the apparatus for registering the values of the constants in-plane magnetic anisotropy in different directions in the plane of the magnetic film, the resulting set of data characterizing a periodic magnetic relief. This set is characteristic of the proposed protective characteristic used to identify recorded in the protective element of the periodic structure and, accordingly, protected with this product.

Another example of the performance of the proposed protective element involves making a separate multi-layer magnetic structure in the form of a thin-film structure on the basis of PET film coated with a soft magnetic layer with in-plane anisotropy and formed therein periodic relief structures. The relief height of 0.01 μm to 0.5 μm, the period of 0.1 μm - 100 μm. The orientation of the strokes relief gratings may vary over the surface of the magnetic film. Such magnetic tape can be placed on the surface or inside the protected product itself, or in combination with other protective elements, not containing magnetic inclusions. The security element from a fake is raised.
