Description

The invention relates to tape-type security elements added to paper pulp during the paper-making process to facilitate evidence of the authenticity of securities, banknotes and documents.

Known tape protective element made of a material having areas that differ in water permeability, which allows to obtain a thinner paper web in places with low permeability (patent EP 0070172). The high porosity of the material allows you to enter a fairly wide protective tape. Protected printing products are made with a protective element.

The disadvantage of this invention is the low degree of protection against counterfeiting.

The invention is aimed at solving the problem of creating the design of a tape protective element of a porous material consisting of fibers and containing a set of security features, both visual and machine-readable, which both are contained in the element itself and appear after its introduction into paper.

The technical result of the present invention is to increase the degree of protection of printed products from counterfeiting.

To achieve a technical result, the security element for authenticating security of printed products is made in the form of a tape of porous permeable material having protective zones of different geometric shapes, differing in optical transparency and / or optical density, located along the length and / or width of the element.

The porous material is made of colorless and / or colored fibers of polypropylene and / or cellulose and / or polyester material.

Protective zones are made in the form of geometric shapes, and / or patterns, and / or inscriptions and are arranged intermittently and / or continuously along the length and width of the strip.

Protection zones are made with a raster image with different sizes and / or different density of raster points.

At least some of the raster points have a given geometric shape.

The security element comprises fibers and / or confetti located within the structure of the porous material and / or on its surface.

Protective confetti and / or fibers are arranged randomly or according to a predetermined algorithm.

The security element includes colored and / or luminescent and / or magnetic and / or electrically conductive materials and / or diffraction gratings and / or a hologram located over the entire surface or part of the surface and / or in the bulk of the porous material.

Protected printing products with a protective element are made so that the protective element is completely in the thickness of the paper or partially on the surface of the paper web.

The invention is illustrated by the accompanying drawings:

figa, 1b - a protective element made of a porous material with protective zones of an intermittent type of various shapes;

figa, 2b - a protective element made of a porous material with protective zones of a continuous type of various shapes;

figa, 3b is a cross section of a protective element with protective zones and a luminescent coating on the surface of the tape;

4 is a cross section of a protective element made of a porous material with transparent protective zones and a holographic image.

The protective element 1 is made of porous permeable material and has protective zones 2. In the case of an intermittent protective zone, it is made of various geometric shapes depending on the stamp used (figa, figb). The protective zone 2 is performed continuous along the length of the protective element 1 also of various geometric shapes (figa, figb). Protective zones 2 of intermittent type are located on the protective element with a frequency that provides at least one zone on a security paper, banknote or document. Protective zones 2 may be arranged in one or more rows across the width of the protective element 1.

Figure 3 (a, b) shows the design of the tape-type protective element 1 made of a porous material with protective zones 2, the surface of which is coated with a colorful coating 3 based on one or more luminescent substances, incl. encapsulated phosphor coating. Luminescent pigments used to create an additional security feature can be either visually visible or machine readable. Luminescent coatings are applied on one surface of the tape protective element (figa), or on both surfaces (figb).

Figure 4 shows the construction of a protective element 1 made of a porous material, with transparent zones 2 carrying a holographic image 4, including Holographic image with hidden mark.

Protection zones 2 can be created in various ways. To obtain transparent zones, they are locally exposed to pressure and / or temperature, deforming the fibers of the material. To obtain zones with a higher optical density, substances are introduced into the composition of the fibers, which, under the influence of temperature or electromagnetic radiation, change their color or apply materials that change the optical transparency / density. In this case, a visual or / and machine-readable image is formed. After being introduced into the paper, this element forms the marks observed in transmitted light. There is a manifestation of these zones in reflected light, including with a change in the picture when observed from different sides of a security, banknote or document.

The width of the protective element 1 tape type of porous non-woven material is from 2 mm to the width of the paper web for the manufacture of security paper, banknote or document. The introduction of a tape protective element of large width provides not only a pronounced visual effect, but also helps to increase the mechanical strength of the paper.

The thickness of the protective element of the tape type of porous material is from 10 to 200 microns.

The porous material is made of colorless and / or colored fibers of polypropylene and / or cellulose and / or polyester material in the form of a homogeneous material or mixture.

The protection zone 2 is performed in the form of a portrait, an emblem, a landscape, a text image, a geometric figure, etc. Image execution can be using raster dots. A grayscale image is formed due to a change in the size or density of the raster dots. The shape and nature of the location of the raster points serve as an additional protective feature, which allows visual inspection to identify the specified shape of the raster points.

The use of security features, such as colored and / or luminescent and / or magnetic and / or electrically conductive materials, diffraction gratings and / or holographic images, confetti and / or fibers of various shapes and chemical composition, including coated with a metal layer and / or luminescent and / or magnetic materials and / or materials absorbing x-ray radiation, along with zones with different transparency and / or optical density formed on a tape made of a porous material, it is possible to obtain a variety of protective tape-type elements .

These protective features are located on the entire surface or part of the surface of the protective element 1 and / or in the thickness of the porous material and in combination with the protective zones 2, which differ in transparency and / or optical density, give the protective element multifunctionality, create a pronounced visual effect to prove the authenticity of valuable papers, banknotes and documents.

Protective confetti and / or fibers, including those having special shapes and / or properties, can be included in the design of the protective element arbitrarily, or in accordance with a certain regularity, for example, in a sinusoid.

The invention is intended to be used as a protective element for secure printing products, while the protective element is completely in the thickness of the paper or partially on its surface. This security element allows both visual and machine verification of the authenticity of security printing products and is a difficult to reproduce element in the manufacture of fakes.
