Abstract

This invention provides a solid coating composition comprising: (A) at least one of a vinyl resin resin and a cellulose resin; (B) a least one of a ketone resin and a xylene resin; (C) an acrylic resin comprising about 40 to about 90% by weight of methyl methacrylate, about 10 to about 60% by weight of at least one of acrylic acid, an acrylic acid derivative, methacrylic acid and a methacrylic acid derivative other than methyl methacrylate, and up to about 10% by weight of a copolymerizable monomer; (D) at least one of benzylidene sorbitol, dibenzylidene sorbitol, tribenzylidene sorbitol and a derivative thereof; (E) at least one of an ether of a glycol, ether ester of a glycol and a benzoic acid ester; and (F) a pigment. The solid coating composition is easy to handle and easy to apply, gives coating film of excellent film properties, and has other excellent advantages.
