Abstract:
An antifouling coating composition comprising:an antifouling agent;a film forming copolymer of 1000 to 50,000 in number average molecular weight, from 20 to 65% by weight of the structural units of said copolymer being derived from a trialkylsilyl ester of polymerizable unsaturated carboxylic acid, wherein said trialkylsilyl ester is represented by the following formula (I): ##STR10##wherein R.sup.1 represents a hydrogen atom or an alkyl group, and each of R.sup.2, R.sup.3 and R.sup.4, independently, is an alkyl group having 1 to 18 carbon atoms;20 to 65 parts by weight per 100 parts by weight of film forming copolymer, of chlorinated paraffin having 8 to 30 carbon atoms, a number average molecular weight of 200 to 1200 and a chlorination ratio (chlorine content) of from 35 to 75% by weight.
