PROTECTED INFORMATION CARRIER WITH OPTICALLY VARIABLE EFFECT, AND METHOD OF MANUFACTURING PROTECTED INFORMATION CARRIER WITH OPTICALLY VARIABLE EFFECT Russian patent published in 2018 - IPC B42D25/00 B32B33/00 G07D7/12 

FIELD: printing industry.

SUBSTANCE: invention relates to the field of protected polygraphy and relates to protected information carrier with optically variable effect and method of its production. Carrier is made on paper, polymer or combined basis and comprises zone with dot patterned raster regular and / or irregular structure applied. Three-dimensional raster is made on top of raster structure in form of embossed linear spatial structure of lattice type and / or concentric and / or honeycomb spatial structure. Points of printed raster are located on side faces, bottoms or white space elements of three-dimensional structure, regardless of positioning of printed and three-dimensional images, with obtaining image that has form of intersecting linear structures on carrier. When viewed at an angle of 90 degrees from plane of carrier, protective element is seen as uniform field of integral color of substrate paints, and when observing carrier at an acute angle, change in color of element to integral one is observed, mixture of two colors of substrate, and when carrier is rotated, moire pattern appears, and depending on rotation angle, color change and / or pattern of moire pattern is observed, pattern being shown as continuous moire bands, intermittent bands and / or may have lattice structure in form of intersecting moire strips.

EFFECT: invention provides enhanced degree of protection of information carrier and durability of use.
