COATING AGENT, FILM, LAMINATE AND ARTICLE WITH PROTECTED SURFACE Russian patent published in 2019 - IPC C09D175/16 C09D4/02 B32B27/26 B32B27/40 B32B27/30 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to the field of protective films for protecting the surface from external effects and relates to a coating agent, a coating film, a laminate and an article with a protected surface. Invention provides a coating agent which can be shaped to a surface layer having excellent self-healing properties and dirt-protective properties, by applying a coating agent on the surface of the base material (for example, thermoplastic polyurethane) and curing the obtained material. Coating agent according to the present invention contains a urethane(meth)acrylate (a) based resin, fluorine-containing compound (b) and photopolymerisation initiator (d). Average molecular weight (Mw) of the urethane (meth) acrylate (a) based resin ranges from 10,000 to 800,000. Fluorine-containing compound (b) contains at least two polymerisable functional groups and a derivative of fluorosilsesquioxane (c) contains at least one polymerisable functional group.

EFFECT: surface layer obtained from a coating agent has excellent self-healing properties during scratching, dirt-proof properties and stretchability.
