The invention relates to a protective elements used for visual authenticity control of security printing products, such as securities, Bank notes, ID.

In patent WO 98/36913 described protective element for the authenticity control of security printing products, made in the form of a paint layer, deposited on a substrate and having a blind areas resulting from exposure to laser radiation on the layer of paint for the formation of images that can be detected by visual inspection.

A limitation of known technical solutions is the lack of security printing products.

The technical result of the invention is to increase the degree of protection of printed products by creating more difficult to tamper with the protective element with the use of optically variable image.

This technical result is achieved by the fact that the proposed protective element for the authenticity control of security printing products, made in the form of a paint layer, deposited on a substrate, and having a blind areas resulting from exposure to laser radiation on the layer of paint for the formation of images that can be detected by visual inspection, according to the invention over the spine of the substrate is made of relief, the image is made, at least on one side of relief when exposed to laser radiation at a selected angle to the relief surface.

The cross section of the elevation profile of the protective element is made of a triangular shape. The angle of inclination of the faces of the relief surface of the substrate is 45°.

The terrain is made in the form of mesh elements stamping, forming more than two surfaces for drawing the image.

The substrate is metallized or metallized layer, interference or color paint.

The paint layer is applied by way of offset, flexo or screen printing.

Secure printing products are made with the proposed protective element.

The invention is illustrated by the following drawings:

Figure 1 - image of the location of blind areas in the absorbing layer of paint on one of the two relief surfaces of the substrate;

Figure 2 - image of the location of blind areas in the absorbing layer of paint on one of the three surfaces, when the relief is formed cellular elements stamping;

Figure 3 - the protective element with the image in relief;

4 is an image obtained when considering in the direction A;

5 is an image obtained when considering in the direction B.

Figure 1 shows the location Beckers is cnyh plots in the form of holes 1 in the layer of radiation-absorbing in the wavelength of the laser dye 2, formed as a result of laser irradiation on the relief surface of the substrate 3 with the linear embossing elements having in cross section a triangular shape. The corner solution of 4 faces of relief when the embossing is about 90° (ratio b/a is close to 0.5). The substrate 3 may be used paper, polymeric material, paper with a polymer coating. The substrate 3 may have the additional layer 5, for example, may be metallized or coated metallized, interference or color paint under the top layer of the absorbing paint 2 subjected to selective exposure to laser radiation when applied image under certain given angle to the relief surface.

Figure 2 shows the image formed blind areas in the form of holes 1 in the absorbing layer of the ink 2 formed as a result of laser irradiation on the relief surface of the substrate 3, which may be used paper, polymeric material, paper with a polymer coating. The substrate can have an extra layer 5, for example, may be metallized or coated metallized, interference, color paints. As in the embodiment according to figure 1 the upper layer of the ink 2, absorbing in the region of wavelengths corresponding to the laser wavelength, is subjected to behold the subjective effects of laser radiation under a specific set of angles for drawing the image. The relief surface of the substrate 3 formed honeycomb embossing elements 6, forming more than two surfaces for drawing the image.

The proposed protective element is an optically variable image, and is easily detected visually when the angle of observation.

The relief is created on a previously sealed surface (substrate) by the method of metallographic (flat), embossing or any other type of embossing, using forms that allow to obtain the necessary relief.

The substrate can be pre-sealed by means of offset, flexo, screen printing metallized, or interference, or colored paint or covered with a metal layer by plating the surface, followed by applying a layer of absorbing ink.

The substrate may be pre-applied layer of polymer or any other material, well perceiving the form when it is embossed to form a relief on it.

When the image drawing method of selective laser exposure on one surface with a linear or mesh elements observed one optically variable image, i.e. the image of the invisible at the same observation angle and visible at different viewing angle (Fig.3-5).

When the image drawing method behold the objective of laser irradiation on more than two surfaces of the relief, formed cellular elements, there are several images, each of which is invisible at the same observation angle and becomes visible when changing the angle of observation.

The proposed protective element is designed to run on a secure printed products for rapid visual authenticity control.
