MULTILAYERED POLYMERIC PRODUCT, SUCH AS IDENTIFICATION DOCUMENT Russian patent published in 2015 - IPC B42D25/00 B42D25/328 D21H21/44 D21H21/48 

FIELD: textile, paper.

SUBSTANCE: invention relates to a polymeric multilayered product, such as the identification document. It includes several polymeric layers joined according to direct bonding (without glue) technology according to which at least in one of layers the colour identifying individualizing images are recorded. Images are recorded in the form of translucent pixel arrays consisting of thin-film pixel elements with subpixel structures consisting of areas with metallised diffraction lattices the reflectivity of which at the pre-set lengths of light waves is changed at the product individualization by the methods of laser engraving of diffraction lattices with precise directing of laser beam towards areas of their location. At least two polymeric layers are mutually joined by means of agglomeration. Pixel matrixes are created on surfaces between the agglomerated layers, one of which is transparent, and consist of pixels with the sizes from 30 up to 200 mcm mutually spaced at the distance from 30 to 500 mcm so that the pre-set value of transparency of the obtained images amounts from 50 up to 99%, and the area of the metallised diffraction lattices does not exceed 50% of the area of the layer where they are located.

EFFECT: creation of the identification document, improvement of protection of important documents.
