PAINT COMPOSITIONS , METHOD OF PAINT FINISHING AND PAINTED OBJECTS

摘要

To provide a paint composition which contains as essential components (A) a carboxyl group containing resin obtained by the copolymerization of a carboxyl group containing radically polymerizable monomer and other radically polymerizable monomer in which two or more carboxyl groups are included in one molecule and of which the acid value is from 100 to 300 mgKOH/g and the weight average molecular weight is from 2,000 to 30, 000, and wherein from 5 to 50 mass% of structural units based on a lactone compound are included in the resin solid fraction, (B) an epoxy group containing resin where two or more epoxy groups are included in one molecule, (C) ultraviolet absorber and (D) a light stabilizer of which the basicity (pKb) is at least 9, and in which the proportions as a mol ratio of the carboxyl groups of the (A) component and the epoxy groups of the (B) component are within the range from 75/25 to 25/75, a method of finish paining and the resulting painted objects.
