IDENTIFICATION DOCUMENT INFORMATION PAGE, IDENTIFICATION DOCUMENT, PRE-LAMINATED MULTI-LAYER DESIGN FOR IDENTIFICATION DOCUMENT WITH ANTI-DELAMINATION PROTECTION. Russian patent published in 2021 - IPC B42D15/00 B32B29/00 

FIELD: printing materials.

SUBSTANCE: invention relates to multilayer printed materials for special purposes and can be used in the manufacture of passports, identity cards and other identification documents, as well as contactless prelams based on polycarbonate. An identification document with a multi-layer information page or a contactless prelam for an identification document, or an identification document in form of a plastic card, is equipped with a chip placed between two internal layers of polycarbonate. In the area of the chip placement, covering the entire area of the chip placement, glue points are applied sequentially, made of an adhesive composition that has the ability to soften the inner layers of polycarbonate in the area of the chip placement, made on the basis of a polymer selected from polyvinyl acetate, polyvinyl chloride, polyvinylidene chloride, bituminous resins, aminosmols, phenolic resins, polyamides, polyacrylates, polymethylmethacrylates, styrene resins, epoxy resins, natural and regenerated rubbers, synthetic elastomers based on polychloroprene, copolymers of acrylonitrile with divinyl, copolymers of styrene with divinyl, and organic solvents or water.

EFFECT: increased immunity of the information page of the identification document in the chip zone to the influence of climatic factors during storage and operation, as well as to rapid temperature changes.
