A process for production of a powder coating comprising: copolymerizing a monomer mixture comprising a (meth)acrylate monomer having branched or cyclic substituents of four or more carbon atoms in its side chain and a (meth)acrylate monomer having functional groups to form a thermosetting vinyl copolymer (a) having a glass transition temperature of approximately 40 to 100°C and a number average molecular weight of approximately 1,000 to 10,000; dissolving or dispersing said copolymer (a) and a crosslinking agent (b) in a solvent comprising approximately at least 50% by weight based on the weight of the solvent, of tert-butanol, to form a resulting coating solution having a melting point of not less than approximately -30°C; and lyophilizing said coating solution under a pressure not higher than approximately 50 mmHg. The present process produces a powder coating without polymerization due to progression of reaction upon heat generated during production, and without generation of gelated material.
