STAIN-PROOF COATING COMPOSITION, METHOD FOR PRODUCTION OF THE COMPOSITION, STAIN-PROOF COATING FILM FORMED BY USING THE COMPOSITION, COATED ARTICLE HAVING THE COATING FILM ON THE SURFACE, AND STAIN-PROOFING TREATMENT METHOD FOR FORMING THE COATING FILM

摘要

The present invention provide a composition for forming an antifouling coating film that is highly environmentally friendly and effectively exhibits an antifouling effect in seawater for a long period of time. Specifically, the present invention provides an antifouling coating composition comprising: (1) a polymeric plasticizer comprising an ethylenically unsaturated carboxylate polymer having a glass transition temperature of not greater than -20°C and a number average molecular weight of 500 to 20,000; (2) a triorganosilyl (meth)acrylate copolymer, which is a copolymer of triorganosilyl (meth)acrylate monomer A represented by General Formula (I): wherein R 1 represents a hydrogen atom or methyl group, and R 2 to R 4 may be the same or different independently and represent a branched alkyl group having 3 to 8 carbon atoms or phenyl group, with ethylenically unsaturated monomer B other than the monomer A, the triorganosilyl (meth)acrylate copolymer having a glass transition temperature of not less than 0°C and a number average molecular weight of 5,000 to 100,000; and (3) an antifoulant.
