Abstract
To provide a powder coating composition being capable of forming a coating film which has good pigment dispersibility, is excellent in weather resistance, film forming ability, appearance and stain-proofing property and, when used for PCM, is difficult to cause cracks because of its particularly excellent bending resistance at the time of bending of a metal plate. The powder coating composition comprises a powder which contains 100 parts by weight of a vinylidene fluoride copolymer having a melting point of not higher than 150° C., a crystallinity of not higher than 35% and a weight average molecular weight (Mw) of 1×10 to 5×10 and 10 to 400 parts by weight of a methyl methacrylate copolymer having a glass transition temperature of not higher than 110° C. and a weight average molecular weight of 1×10 to 5×10 ; an average particle size of particles constituting the powder being from 1 to 100 &mgr;m and an apparent density of the powder being from 0.2 to 1 g/ml.
