The present invention provides a composition for forming an antifouling coating film with high environmental safety, which dissolves for a long time even if the antifouling coating film is exposed to sunlight for a long time, even in draughts where aquatic organisms may adhere. Parts can also show good antifouling properties. According to the present invention, an antifouling coating composition is provided, which contains a copolymer A, a silyl carboxylate B, and a monocarboxylic acid metal salt C, wherein the copolymer A is a combination of a monomer (a), a monomer ( b), obtained by copolymerization of a mixture of ethylenically unsaturated monomers (c), the above-mentioned monomer (a) is represented by the general formula (1), the above-mentioned monomer (b) is represented by the general formula (2), the above-mentioned carboxylic acid Silyl ester B is a silyl ester of a carboxylic acid other than an ethylenically unsaturated carboxylic acid. |
