Zusammenfassung:PROBLEM TO BE SOLVED: To provide a coating composition for chrome plating forming a coated film maintaining high adhesiveness to a chrome plated surface even for a chrome plated material with deteriorated adhesiveness over a long period and having excellent chemical resistance and to provide an article having the coated film composed of the composition. SOLUTION: The coating composition for chrome plating comprising a vinylic polymer (A) prepared by polymerizing a vinylic monomer mixture containing a vinylic monomer having an amino group and a compound (B) having an epoxy group and a hydrolyzable silyl group in one molecule as follows is used. The glass transition temperature of the vinylic polymer (A) is
