Zusammenfassung: | Disclosed herein is a paint composition comprising a carboxyl group containing resin comprising two or more carboxyl groups per molecule, having an acid number of from 100 to 300 mgKOH/g and a weight average molecular weight of from 2,000 to 30,000, obtained by the copolymerization of a carboxyl group containing radically polymerizable monomer and another radically polymerizable monomer, wherein the carboxyl group containing resin comprises 5 to 50 weight percent of structural units based on a lactone compound, based on resin solids; an epoxy group containing resin, comprising two or more epoxy groups per molecule; an ultraviolet absorber; and a light stabilizer having a pKb value of at least 9; wherein the molar ratio of the carboxyl groups of the carboxyl group containing resin to the epoxy groups of the epoxy group containing resin is 3:1 to 1:3. |
