Abstract: The present invention provides a plated resin molded article having a high adhering strength of a plating layer. Specifically, it provides a plated resin molded article that has a metal plating layer on the surface of a thermoplastic resin molded article comprising a composition that contains (A) 10 to 90 mass % of a matrix resin that has a water absorption after 24 hours in 23° C. water (ISO62) of at least 0.6% and (B) 90 to 10 mass % of a non-styrenic resin that has a water absorption after 24 hours in 23° C. water (ISO62) of less than 0.6%, wherein the thermoplastic resin molded article is not subjected to etching with a heavy metal-containing acid.

Abstract: The present invention provides a plated resin molded article that has a beautiful and strong plating layer. More particularly, it provides a plated resin molded article containing a resin molded article, the surface of which has not been subjected to a roughening treatment by chromic acid etching, and a metal plating layer formed on the surface of the resin molded article, the resin composition containing (A) 10 to 90 mass % matrix resin that has a water absorption (ISO62) after 24 hours in 23° C. water of at least 0.6%, (B) 10 to 90 mass % styrenic resin that has a water absorption (ISO62) after 24 hours in 23° C. water of less than 0.6%, (C) 0 to 40 mass % compatibilizer and (D) 1 to 20 parts by mass, to 100 parts by mass of the total of components (A) to (C), of a water-soluble substance that has a solubility (25° C.) in water of 0.01 g/100 g to 10 g/100 g; wherein the plated resin molded article does not exhibit a change in appearance upon visual inspect-ion after the prescribed heat cycle tests.
