(57) [Summary] [Structure] One or more unsaturated acid anhydrides or unsaturated carboxylic acids (a1) and one or more other unsaturated monomers (a2) copolymerizable therewith are polymerized. Obtained polymer (A) And amino acids, compounds having one or more carboxyl groups in the molecule, compounds having both a hydrophobic group and a hydrophilic group in the molecule, chelate compounds, hydroxyl group- or acetyl group-substituted carboxylic acid esters, layered clay having ion exchange ability Compound group (b1) consisting of mineral powder oleophilized with minerals and organic substances, and polyether compound, polyester compound, polyether polyester compound, olefin glycol compound, acrylic acid ester, methacrylic acid ester and polycarbonate type A coating composition and an antifouling coating composition, comprising a compound and one or more compounds (B) selected from one or both of the compound group (b2) having crystallinity. [Effect] It is possible to form an excellent coating film that does not gel like when kneaded with a copper compound, and does not have the danger of organotin copolymers, and also has good coating film wear resistance and antifouling performance. Can be maintained for a long time. |
