摘要： The invention provides a thermosetting powder coating composition comprising (A) a vinyl copolymer having a number average molecular weight of 1,500 to 6,000, a molecular weight distribution of 1.0 to 1.5 as represented by a weight average molecular weight/a number average molecular weight and a glass transition temperature of 40 to 100°C, the copolymer containing at least one species of functional group selected from the class consisting of epoxy group, carboxyl group and hydroxyl group, and
(B) a curing agent.
The thermosetting powder coating composition of the invention is superior in any of the finished appearance of coating film and the blocking resistance.
