Disclosed is a coating film which is excellent in scratch resistance and excellent in weather resistance, stain resistance, chemical resistance, bending resistance and impact resistance, and is useful as an anti-scratch film or a decorative film. In a film comprising a crosslinked product of a composition comprising a vinyl compound copolymer and a polyisocyanate, the vinyl compound copolymer comprises the following monomer unit: (A) a vinyl compound having no siloxane structure and no hydroxyl group (a Mol%), (B) a vinyl compound having a polydimethylsiloxane structure and not having a hydroxyl group (b mol%), (C) having a linear or branched alkyl group having a hydroxyl group, A vinyl compound having 1 to 6 carbon atoms (c mol%), and (D) the following formula: CH 2 ═C (R) —COO—Y [where R is H or CH 3 , Y is a terminal Is a linear or branched saturated hydrocarbon group having a hydroxyl group at Y, Y is optionally a ring-opening lactone group (—CO— (CH 2 ) n—O—, where n is an integer of 4 to 6). , Carbo 1 selected from the group consisting of a carbonate group (—O—CO—O—), an ester group (—CO—O—), an ether group (—O—) and a urethane group (—NH—CO—O—) A vinyl compound (d mol%), which may have the above groups and has 40 to 120 carbon atoms], wherein a to d are a + b + c + d = 100 and the following formula (1 ) To (3): 0 <{b / (a + b)} x100 ≦ 5 (1), 3 (c + d) / 4 ≦ (a + b) ≦ 4 (c + d) (2), 4d / 3 <= C <= 40d ...
