Abstract: There is disclosed a resin composition for powder coatings, which comprises a blend of two acrylic resins being obtained by polymerizing a proscribed 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 DEG 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. wherein R1 and R2 each represent a hydrogen atom or a lower alkyl group. Disclosure described provides a resin composition for powder coatings that can form a coating film having a mat smooth appearance and excellent in flexibility as shown Du pont impact resistance and the Ericksen test as well as excellent in nail scratch resistance.

Abstract: A resin composition for powder coatings that comprises a composition (A) and a blocked polyisocyanate compound (B), the composition (A) being based on both a carboxyl group containing polyester resin having a hydroxyl value of 10 to 100 and a softening point of 50 to 150 DEG C and a glycidyl group containing acrylic resin having a hydroxyl value of 30 to 150 and a softening point of 50 to 150 DEG C, and further containing a copolymer prepared by reaction between said polyester and acrylic resins. This resin composition is capable of providing an ideal paint film that possesses the features of a paint film prepared from polyester resins (high degrees of smoothness, gloss and strength) and those of a paint film prepared from acrylic resins (high levels of hardness, stain resistance and weatherability).
