PROBLEM TO BE SOLVED: To provide an antifouling coating composition capable of forming an antifouling coating film capable of achieving both long-term antifouling property and crack resistance of a coating film in seawater and fresh water. SOLUTION: A silyl ester-based polymer (A), a structural unit (b-1) derived from styrene, and a structural unit (b) derived from a polymerizable monomer (b2) represented by the formula (b2). An antifouling coating composition containing the copolymer (B) having -2). Equation (b2): CH 2 = CH-COO- (R b1- O) n- R b2 [In the formula (b2), R b1 is an alkanediyl group having 1 to 5 carbon atoms, R b2 is an alkyl group having 1 to 5 carbon atoms, and n is an integer of 1 to 3 carbon atoms. ] [Selection diagram] None |
