PURPOSE:To obtain a coating composition consisting of an acrylic copolymer obtained by subjecting a specific monomer to suspension polymerization in the presence of a polymerization initiator and organic solvent, and capable of providing excellent stain preventing performance when applying to an article having a polyvinyl chloride layer on the surface. CONSTITUTION:The objective composition obtained by blending (A) an acrylic copolymer having 100000-10000000 average molecular weight obtained by subjecting (i) a monomer mixture consisting of 60-90wt.% methyl methacrylate, 2-20wt.% alpha,beta-ethylenic unsaturated monomer (e.g. 2,2,2-trifluoroethyl acrylate) containing fluorine element in the molecule and 8-20wt.% other copolymerizable monomer (e.g. acrylic acid) in the presence of (ii) a suspended polymerization initiator with (B) an organic solvent such as acetone and (C) high polymer compound (less than equivalent amount of the component A) such as polyurethance resin. |
