摘要：An antifouling coating composition includes (A) antifouling agent, (B) filmforming copolymer of 1000 to 50,000 in number average molecular weight, and

structural units derived from a trialkylsilyl ester of polymerizable unsaturated carboxylicacid in an amount of 20 to 65% by weight, and (C) chlorinated paraffin. The compositionmay also contain one or more of (D) (meth)acrylic ester polymer of 1000 to 100,000 innumber average molecular weight; (E) inorganic dehydrating agent, (F) flake pigment, (G)zinc flower. In other embodiments the composition includes above components (A), (B)and (D) wherein (B):(D)=100:10 to 500. Coating films formed from the above antifoulingcoating compositions, such as on a hull or an underwater structure, are excellent incracking resistance, resistance to peeling from ship bottom materials and primer layers,antifouling properties and consumability (self-polishing properties). Further, these

antifouling coating compositions are excellent in storage stability.
