METAL PLATING METHOD ON PLASTIC SURFACE

摘要

<P>PROBLEM TO BE SOLVED: To provide a plating method by which excellent adhesion of a plating film to a plastic surface and the productivity of the plating film during a plating treatment are attained even when a step of etching with an acidic etchant containing permanganic acid is required in a plating process. Ž<P>SOLUTION: The method of metal-plating on the surface of the plastic includes: etching the plastic surface with the acidic etchant containing permanganic acid; successively treating the plastic surface by adding a catalyst and activating the catalyst; and finally metal-electroplating. The plastic surface is treated with a hot aqueous solution after any one of the treatments. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
