ABSTRACT:
According to the present invention, there are provided a coating material composition for chromium plating, which can maintain high adhesion to the chromium plated surface of a chromium plated material having reduced adhesion for a long period and also can form a coating film having excellent chemical resistance, and an article comprising a coating film made of the same. The coating material composition for chromium plating, comprises a vinyl-based polymer (A) obtained by polymerizing a vinyl-based monomer mixture containing a vinyl-based monomer having an amino group, and a compound (B) having an epoxy group and a hydrolyzable silyl group in a molecule, wherein the vinyl-based polymer (A) has a glass transition temperature of lower than 30° C., and the content of the vinyl-based monomer having an amino group is 5% by weight or more and less than 20% by weight in the vinyl-based monomer mixture (100% by weight).
