ADHESIVES WITH LATENT REACTIVITY FOR IDENTIFICATION DOCUMENTS Russian patent published in 2013 - IPC B42D15/10 B32B7/10 B32B33/00 B32B37/12 C08G18/70 C08G18/79 C09J5/06 

FIELD: printing.

SUBSTANCE: group of inventions relates to production of identification documents, made of thermoplastic material and a method of their manufacture. The identification document comprises the layers A), B) and C), at that the layer A) is thermoplastic, the layer B) is made of a storage-stable adhesive with latent reactivity, and the layer C) is thermoplastic, at that the adhesive comprises an aqueous dispersion comprising a diisocyanate or polyisocyanate with a melting point or, respectively, softening point above +30°C and the polymer reactive towards isocyanates, which is polyurethane composed of crystallised polymer chains which, according to the study results, by thermomechanic method at temperatures below +110°C decrystalise partially or completely.

EFFECT: exclusion of layers stratifying.
