Description

Security paper

A useful model can be used in the manufacture of valuable bh-mage. such as: banknotes, bonds, checks, etc., as well as important documents. requiring protection against fake.

Along with other sources of information, a security is known and the method of its manufacture described in RU 2135667, class B21H21 / 42, 1999. The known security is made of paper material with security elements in the form of a strip. located in the thickness of the paper at three different levels. In the area location; The security element in the paper is made of two windows having a stepped shape. In the zone of the greatest depth of the window, the protection element is located at the surface level; paper material.

Known paper can be chosen as the closest analogue; the proposed design, however, it is not sufficiently protected from counterfeiting.

The technical result achieved due to the proposed security advisory system consists in increasing the degree of its security against counterfeiting

The utility model is illustrated by drawings, where Fig. 1 shows a window with a stepped arrangement of a protective thread, Fig. 2 shows a schematic diagram; security paper with embedded security thread.

The indicated technical result is achieved by the fact that, like the j closest analogue, the security paper (Fig. 1) contains paper mother 1L 1 i with security elements, including security thread 2 embedded in the material, which is located in the paper at different levels (a, b , c) and installed with the possibility of its occurrence on the surface of the paper in the zone (a) of the greatest depth of the step windows formed by the paper (Fig. 2). In accordance with this proposal, the paper material introduced fibers of impurity-free 100% pure HOBOFI cotton, while the security elements, in addition to the aforementioned filament, contain several fluorescent fibers and at least one multi-color and / or three-dimensional watermark, which is located at least -mags Watermarks should not be too complicated (heavy), which can complicate printing and paper processing.

The tolerance for the displacement of the watermark in the longitudinal and transverse directions of the relative preset position is ± 3 mm; The latter is made in the form of photographs, and the protective thread is made of polyester and metallized in a vacuum way. The metallized coating of the thread is made possible to dissolve in a solution of sodium hydroxide, which facilitates the processing of recycled paper.

The width of the protective thread is in the range of 1.15 - 1.25 mm, and its thickness is in the range of 27 - 33 nm. The load index at break of the protective thread is not less than 300 g, and its fluorescence intensity according to the blue cabinet is in the range of 4-6. The security thread is colored and dyed with a fluorescent pigment with the possibility of glowing with ultraviolet light from both sides with blue light. The specified pigment is stable when wet.

The security thread is made with demetallized printed silvols. such as, for example, individual letters or nadpie made by ultra-thin lines mainly in English. The thread and symbols are weaved with the possibility of their clear visibility only in the gleam, while other elements of the banknote are visible in reflected light. The height of letters and / or inscriptions is in the range of 0.85 - 0.95 mm. The tolerance for the deviation of the center line ouk from the center line of the security thread is not more than ± 0.05 mm. Metallized background can be with or without demetallized bands between) groups of demetallized characters.

The thread included in the paper should be firmly connected to the internal fiber matrix and withstand the strength test (tearing, elasticity) in the Instron tester.

The thread should not be pulled out of 63 mm wide paper and must withstand a load of at least 300 gf. The gap should only occur with excessive force.

The thread should be resistant to 90 ° C and upv. relative humidity of 80% within 14 days.

The fluorescent pigment should not migrate from the filament to adjacent iacTKv papers in wet conditions.

After exposure to chemicals for the time specified in table 1 and under certain conditions, the color and intensity of the fluorescence resistance should remain the same, and the signs should remain clear.

In addition to the indicated characteristics, the thread should be embedded in the paper in such a way that on the banknote it will either immerse itself in the paper in a certain way, or appear on the surface according to a given pattern.

The thread must satisfy the following additional conditions: 1. The grip of the alternately rising, and sinking thread with the surface of the paper.

When tested in a standard Insrtron tester, the resistance of paper with the thread tied above to abrasion (peeling) should be at least 25 gs.

2Ltrrverka deterioration of the characteristics of alternately rising and engulfing threads.

A standard sample of paper with the above thread after adverse effects in a standard test setup should have the following:

a) fiber connections between the gaps in the sample should not have more than 20% cracks;

3. The torsion test is transversely lifted and immersed in ttttttt

A sample with the above thread, after twisting tests in a standard test installation of the UT type, creating a twisting force in the IO kts, should have the following characteristics:

a) gaps between the fiber compounds in the gaps but should be more than 20%;

b) the formation of loops in the gaps of the test sample should not exceed 30%.

Test conditions

Test temperature range 23 ° C ± relative humidity 50% ± 5%, unless special conditions are specified.

The colored fluorescent fibers that are part of the security elements are made in three different colors, are distributed evenly over the area of the paper and should be visible on both sides in ultraviolet light, giving yellow, green and blue colors.

Distribution: the minimum density of fiber distribution over the paper area is 18 fibers in a plot measuring 50 mm x 50 mm (top view).

Security paper is made on a mesh forming cylinder: e. It is made calendared on both sides, has shades and is smooth, i.e. does not have any inclusions, roughness and foreign particles.

The dye used for paper should be optically inert and not f. 11 should be resorbed in ultraviolet light.

Description of the equipment used: based on the data of a standard colorimetric observer CIE (CIE) with a D65 lamp for observation at an angle of 10 degrees (table 2).
