Abstract
Provided herein are a copolymer obtained by copolymerizing at least an ultraviolet-stable polymerizable monomer and a cycloalkyl group-containing polymerizable monomer, a process for producing said copolymer, and a coating composition containing said copolymer. The copolymers retains outstanding weather resistance over a long period of time owing to the multiplicated effect of an ultraviolet-stable monomer and a cycloalkyl group-containing polymerizable monomer, and the coating composition containing the copolymer forms a coating film having superior gloss, buildability, solvent resistance, and chemical resistance.
