(A) having a poly (perfluoroalkylene ether) chain and a styryl group at both terminals thereof and at least one functional group selected from the group consisting of a hydroxyl group, an isocyanate group, an epoxy group, a carboxyl group, an acid anhydride group and a carboxylic acid halide group (b) is reacted with a polymer (P) obtained by copolymerizing a polymerizable unsaturated monomer (B) having an unsaturated group (b) as an essential monomer component with a polymerizable unsaturated monomer having a hydroxyl group, an isocyanate group, an epoxy group, And a compound (C) having at least one functional group (c) selected from the group consisting of a carboxyl group and a carboxylic acid halide group and a polymerizable unsaturated group. This fluorine-curing resin can be added to the active energy ray-curable composition to impart antifouling properties to the cured coating film and exhibit stain-proofing properties even when contacted with chemicals such as alkali. |
