Fluorine based copolymer, water repellent surface modifier, curable resin composition and water borne coating film

摘要

A fluorine-based copolymer that can obtain a surface having excellent water-sliding property and can be suitably used as a water-sliding surface modifier, a curable resin composition using the same, and a cured product of this composition. Provide an aqueous coating. Specifically, a polymerizable monomer (a1) having a fluorinated alkyl group represented by CnF2n + 1- (where n is 1 or 2) and a polymerizable unsaturated group, and an alicyclic hydrocarbon. A fluoropolymer characterized by being a copolymer containing a polymerizable monomer (a2) having a skeleton and a polymerizable unsaturated group as an essential raw material, and a water-sliding surface modifier comprising the same. , A curable resin composition containing this and a cured coating film which is a cured product thereof are used.
