Resin composition for powder coating

A powder coating resin composition comprising (A) a phosphorus-containing vinyl polymer containing a curable functional group and having a softening point, determined by the ring and ball method, of 70.degree. to 150.degree. C. and a number average molecular weight of 1500 to 30000, and (B) a curing agent.

Powder coating resin composition

A thermosetting resin composition for powder paints, which comprises I. a polymer having a softening point, as measured by a ring-and-ball method, of 80.degree. to 150.degree. C. and a number average molecular weight of 3,000 to 15,000 and derived from (1) 10 to 40% by weight of .beta.-methylglycidyl (meth)acrylate or a mixture of it with glycidyl (meth)acrylate, (2) 20 to 80% by weight of styrene, (3) 3 to 40% by weight of a dialkyl ester of an aliphatic unsaturated dibasic acid and (4) 0 to 30% by weight of an alkyl (meth)acrylate, and Ii. an aliphatic saturated dibasic acid.
