ABSTRACT:
A process is disclosed for the direct electroplating of a non-conductive material comprising non-conductive surfaces and metallic surfaces. The process involves contacting the non-conductive material with a compound capable of selectively forming a sacrificial layer on the metallic surfaces which sacrificial layer is substantially insoluble in alkaline or neutral media but soluble in acidic media. The foregoing step is followed by deposition of carbon onto the surfaces followed by contact with an acidic solution and subsequent electroplating.
