LAMINATED ARTICLE ON PAPER OR POLYMER SUBSTRATE (VERSIONS) AND METHOD OF ITS MANUFACTURING Russian patent published in 2014 - IPC B42D25/342 B32B33/00 

FIELD: textiles, paper.

SUBSTANCE: laminated article on paper or polymer substrate with optically variable structure comprises a coating in the form of printing raster and a three-dimensional raster. The coating is formed on one side of the substrate, and the three-dimensional raster is applied to the other side of the substrate. The field of printing or the three-dimensional raster is divided into two or more sectors which are displaced relative to each other. Each sector has a different colour so that when changing the view angle the colour of the sectors on the image changes. The three-dimensional raster is made in the form of elements with a symmetrical and/or asymmetrical profile to form a relief on both sides of the substrate and is positioned relative to the printing raster so that the three-dimensional raster is at least partially located above the printing raster. The width of the printing raster lines is from 50 to 200 microns, the width of the three-dimensional raster lines is 100 to 600 microns, the angle between the elements of the printing and the three-dimensional rasters is from 0° to 10°, at that they form a moire image, which when observing the data medium under the right angle is concealed, and when observing the data medium at an acute angle becomes visible.

EFFECT: improving security of articles, increased manufacturability and reducing the cost of the security element due to reduction of runs in the printing machine.
