An antifouling coating composition comprising (A) a film-forming polymer, (B) a volatile organic liquid diluent in which the polymer (A) is dissolved, (C) an antifouling agent and (D) optional other additives, characterizing by containing, in addition to said (A), (B), (C) and (D), disintegration type crosslinked acrylic resin microparticles having an average grain diameter of 0.01 to 250 mu and containing a number of metal ester bond bearing crosslinks uniformly distributed within the particle bodies, prepared by polymerizing 5 to 98% by weight of at least one metal ester bond bearing multifunctional polymerizable monomer defined in the specification 95 to 2% by weight of at least one polymerizable monomer other than said metal ester bond bearing multifunctional monomer, the solid weight ratio of said microparticles to the film-forming polymer being 1:99 to 77:30. The present antifouling coating composition can exhibit excellent polishing property and long-lasting antifouling effect.
