Abstract
There is disclosed a resin composition for powder coatings, which comprises a blend of two acrylic resins obtained by polymerizing a prescribed amount of monomer component (a-1) represented by formula (I) and a prescribed amount of another monomer component (a-2), respectively, and having different polymerization degrees represented by viscosities at 140.degree. C. and a polybasic acid compound in 1.5 to 0.5 equivalent ratio of the glycidyl groups in said acrylic resins to the acid groups in the polybasic acid compound. ##STR1## wherein R.sub.1 and R.sub.2 each represent a hydrogen atom or a lower alkyl group. The resin composition for powder coatings that can form a coating film having a mat smooth appearance and being excellent in flexibility as shown by Du Pont impact resistance and the Ericksen test as well as being excellent in nail scratch resistance.
