ANTI-COUNTERFEIT SECURITY IDENTIFICATION MARK AND METHOD OF MAKING IT

Objects, related to an anti-counterfeit identification mark, a paper, defended from counterfeit with identification marks, placed on its surface (two variants), method of making a check or control tape from such a material, are claimed. The present invention relates to identification tools of documents made from paper, polymeric materials or their combination, being rolled at least at the stage of personalized information application to cash register check or control tapes or similar systems. The gist of the invention related to the identification mark comprises that the layer possessing diffraction relief structures has a region, angular dispersion of which for given light wavelength, direction of light source and given order of diffraction maximum has corresponding value; wherein the multilayer protective element is fully placed on a paper along element transverse axis, and region, done along element transverse axis, is placed along the full length and properly oriented. The gist of the invention related to the defended from counterfeit paper with said identification marks, placed on its surface is the following. According to the first variant of the paper implementation, when placing of n identification marks on a paper in longitudinal and transverse directions with; specified spacing and origin, region angular dispersion of every subsequent mark in longitudinal direction differ from region angular dispersion of every previous mark of the same direction on given value, wherein distinctiveness repetition is periodical. According to the second variant of the paper implementation when placing of n identification marks, made according to Claims 1-2, on a paper in longitudinal and transverse directions with specified spacing and origin, region angular dispersion of every mark in longitudinal direction has constant value. The gist of the check or control tape obtainment method from the paper, imolemented according to any said variants comprises that the identification marks on the paper are made in accordance with Claims 1-2, wherein after marks placing the paper is cut into rolls in accordance with check: or control tapes characteristics in such a way that identification marks are located along at least] one edge 'of check or control tape in longitudinal direction, meanwhile the size of edge mark along1 longitudinal check or control tape axis is 1/2 part of identification mark.
