Abstract: A polyamide resin is disclosed. Moldings of the polyamide resin composition are lightweight and have high mechanical strength including high flexural strength and high flexural modulus, as well as good heat resistance, good impact resistance and good metallic appearance. In the polyamide resin composition, the polyamide resin is reinforced with from 0.1 to 10% by weight of a layered silicate uniformly dispersed therein on a molecular level. To 100 parts by weight of the reinforced polyamide resin are added from 0.1 to 10 parts by weight of particles capable of expressing a metallic color.

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.degree. to 150.degree. C. and a glycidyl group containing acrylic resin having a hydroxyl value of 30 to 150 and a softening point of 50.degree. to 150.degree. 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).
