The invention relates to printing and can be used in the production of printed products such as banknotes, cheques, CR is

Known element to protect documents from tampering [1], which is a film carrier with a removable cover, a metal foil, which is the basis for an element with variable optical form, and the adhesive layer, heat-sensitive or pressure, to connect to the protected document.

The disadvantages of this item is that it does not exclude the possibility of play, because when heated, the adhesive softens and protects the picture can be easily separated from the document without violating its integrity.

The closest technical solution of the present invention, selected as a prototype, is protected printed matter [2], containing a base, a layer of high temperature adhesive, on which print is made to protect the image, for example a hologram, with a layer of high temperature adhesive attached by heating to the ground, and on its outer surface is applied a transparent layer.

In the known solution also does not exclude the possibility of imitation of the document, so as to protect the image can be separated from the document without destruction by heat.

The objective of the invention is the s by creating conditions, contributing to the destruction of protecting the image when you try to separate the element from protected document, and simple to manufacture.

The problem is solved in the element for protection of the document against forgery, containing a base of translucent material and consistently located the layer protecting the image, the first layer of hot-melt adhesive and a protective layer, in which according to the invention between the substrate and the layer protecting the image is placed a second layer of adhesive, the thickness of which is less than the thickness of the first layer of adhesive, thus protecting the image is preferably in the form of a hologram. Additionally, between the layer protecting the image and the first and second layers of adhesive are placed respectively in the first and second layers regulator of adhesion, each of which can be made solid or in the form of a separate, equally-spaced sections, for example in the form of strips or squares, and separate evenly distributed areas of the first layer of the regulator of adhesion does not cover separate evenly distributed areas of the second layer of the regulator of adhesion.

Accommodation in the element for protection of the document against forgery layer sushisushi the establishment, less than the thickness of the layer of hot-melt adhesive side of the protective layer, leads to the fact that protecting the image, in particular hologram is located inside a homogeneous plastic hot melt adhesive, which creates conditions that lead to the fact that in the case of unauthorized separation of the element from the protected document by heating is the destruction of the hologram.

Application between layers of hot-melt adhesive and a hologram additional layers of control adhesion, which can be either solid or in the form of uniformly distributed areas in the form of strips or squares that do effect the adhesion of uncertainty.

The execution of protecting the image in the form of a complex hologram, which made special protective elements, which is proprietary to the applicant, in addition protects the element from the simulation.

In Fig. 1 shows a construction element for protection of the document against forgery; Fig. 2 - another option is the construction of the element to protect the document against forgery; Fig. 3, 4 - completion form layers regulator of adhesion.

Element for protection of the document against forgery (Fig. 1) consists of a base 1 made of translucent material the hologram, the first layer 3 of the adhesive, the protective layer 4, for example made of paper, and the second layer 5 of the hot-melt adhesive. The element may also contain the first and second layers 6, 7 of the regulator of adhesion, such as varnish on the basis of peat wax (Fig. 2). Each of the layers 6, 7 of the regulator of adhesion may be performed either in a separate evenly distributed areas in the form of strips (Fig. 3) or squares (Fig. 4).

Element for protection of the document against forgery is made as follows. Transparent, mechanically strong film, such as Mylar, a layer of hot-melt adhesive to which a method of hot stamping joins the hologram. On top of the hologram is applied to the second layer of the same hot-melt adhesive and a protective layer of paper, intended to preserve the adhesive property of the adhesive. When applying the element to the document, it may be laminated, with a layer of paper removed.

5. The element at PP. 1 and 3, characterized in that each of the layers regulator of adhesion is made in the form of separate uniformly distributed areas in the form of strips or squares, with separate evenly distributed areas of the first layer of the regulator of adhesion does not cover separate evenly distributed areas of the second layer of the regulator of adhesion.
