Abstract:
A thermosetting (meth)acrylic powder paint consisting essentially of:at least one acrylic and/or methacrylic copolymer (A) having a number average molecular weight of 3,500 or less which is obtained by polymerization in a reaction system containing an ethylenic unsaturated monomer having at least one glycidyl group and at least one unsaturated double bond in the molecule as a monomer (a1) and an ethylenic unsaturated monomer having at least one unsaturated double bond and no glycidyl group in the molecule as a monomer (a2);at least one polybasic carboxylic compound (B) selected from the group consisting of polybasic carboxylic acids (b1) and polybasic carboxylic anhydrides (b2);particles (C) having a core/shell structure each comprising a core consisting of a synthetic rubber having a calculated glass transition point of 20.degree. C. or below, the core being covered at least partially with at least one shell having a calculated glass transition point of 40.degree. C. or above, and said shell substantially having neither epoxy group nor glycidyl group; andadditives of a powder paint.
