LAYERED MATERIAL, ARTICLE WITH PROTECTED SURFACE AND METHOD OF PRODUCING LAYERED MATERIAL Russian patent published in 2019 - IPC B32B27/40 C09J7/20 C08J7/04 

FIELD: chemistry.

SUBSTANCE: invention relates to the technology of polymer materials and relates to a laminar material for protecting the surface of an article, in which thermoplastic polyurethane is used, and a method for production thereof. Laminar material comprises base film (11) made from thermoplastic polyurethane, and adhesive layer (13) formed on one surface side of base film (11). Base film (11) has surface layer (12) on the side opposite to the first surface, in surface layer (12) there is a mixture of thermoplastic polyurethane and a curable resin composition. Relative content of the curable resin composition is configured to gradually reduce surface layer (12) from the surface (s1) to the inner part of base film (11). Curable resin composition contains at least one fluorine-containing compound (ss) selected from a group consisting of fluorosilsesquioxane and fluorosilsesquioxane polymers, and a curable resin.

EFFECT: adhesive layer (13) has surface roughness of 350–750 nm, providing excellent antifouling and adhesion properties and minimizing the adhesive residue.
