ABSTRACT:
When an N-acylpolylactam or N-acylpolyimide compound is incorporated into an acrylic copolymer containing as a functional group a hydroxyl group, a thermosetting resinous composition suitable for the production of a paint, especially a powder paint, is obtained. A powder paint prepared from this resinous composition does not cause blocking below 50.degree. C. and therefore, it has a very good storage stability. The powder paint has a free flowability at room temperature and exhibits good melt flow characteristics when heated above 130.degree. C. for baking. Coating films prepared from this coating composition are excellent in the mechanical resistance, adhesion to the substrate, weather resistance, corrosion resistance and solvent resistance. When said acrylic copolymer further contains as a functional group a carboxyl or glycidyl group, the resulting resinous composition has further improved properties useful for a paint.
