(57) [Summary] [Structure] (A) General formula (I) (In the formula, R 1 and R 2 each independently represent a hydrogen atom, a chlorine atom, a methyl group or an ethyl group) and one or more unsaturated acid anhydrides and one or more copolymerizable therewith Polymer obtained by polymerizing other unsaturated monomer of (B), triazole derivative, (C) antifouling agent of copper compound, (D) aliphatic amide dispersion and anti-sagging agent, and (E) N -An antifouling coating composition containing a substituted imide poison. [Effect] It does not have the danger of organotin copolymers, exhibits good hydrolyzability, does not thicken and gel when kneaded with a copper compound, and has excellent surface smoothness. A film can be formed. |
