Abstract
Process for producing a copper plated resin article by forming a uniform copper coating having excellent adhesive strength on a fiber-reinforced or unreinforced thermoplastic or thermosetting resin article having a heat deformation temperature higher than 165.degree. C. The resin article is heated along with a source of copper formate under a reduced pressure or in a non-oxidative atmosphere to a temperature in the range above 165.degree. C. but lower than the heat deformation temperature of the resin article. The process makes it possible to produce a resin article having formed thereon a copper layer having an excellent adhesive strength by a very simple manner, and the resin article thus obtained can be used in various industrial fields.
