Abstract:
An antifouling coating composition comprising:an antifouling agent,a film forming copolymer of 1000 to 50,000 in number average molecular weight, said copolymer containing structural units derived from a trialkylsilyl ester of polymerizable unsaturated carboxylic acid in an amount of 20 to 65% by weight, based on the total amount of the copolymer, wherein said trialkylsilyl ester is represented by the formula (I): ##STR10## wherein R.sup.1 represents a hydrogen atom or alkyl group, and each of R.sup.2, R.sup.3 and R.sup.4 is an alkyl group having 1 to 18 carbon atoms; anda (meth)acrylic ester polymer of 1000 to 100,000 in number average molecular weight that is compatible with the film forming copolymer and contains no structural unit derived from trialkylsilyl ester, and wherein the (meth)acrylic ester polymer is contained in an amount of 10 to 500 parts by weight per 100 parts by weight of the film forming copolymer.
