An object of the present invention is to provide an antifouling paint composition capable of forming an antifouling coating film having stable coating film consumption in ships and underwater structures and exhibiting excellent antifouling properties over a long period of time. In order to solve the above problems, an antifouling paint composition of the present invention is an antifouling paint composition containing a hydrolyzable copolymer (A) and an antifouling agent (B), wherein the hydrolyzable copolymer (A) ): (A21) represented by the general formula (II) wherein M represents zinc or copper, and R 2 represents a hydrogen atom or a methyl group, and other unsaturated groups capable of copolymerizing with the monomer (a21) A metal salt bond-containing copolymer having a constituent unit derived from the monomer (a22), and the like, and is characterized by containing at least medetomidine as the antifouling agent (B). |
