Abstract: The process for electroplating a metal layer to the surface of a nonconductive material which comprised the steps:(a) contacting said substrate surface with an alkaline permanganate solution for an effective time and at an effective concentration and at an elevated temperature to prepare said substrate surface for a metal layer to be electroplated thereto;(b) then contacting said substrate surface with an aqueous neutralizer/conditioner solution, said solution comprising water, at least one nuetral or acidic reducing agent, and at least one polyelectrolyte polymer conditioner;(c) then contacting said substrate surface with a liquid dispersion of carbon black comprised of:(1) carbon black particles having an average particle size of less than about 3 microns in said dispersion;(2) an effective dispersing amount of a surfactant which is compatible with said carbon black; and(3) a liquid dispersing medium, wherein the amount of carbon black is sufficient to coat substantially all of the nonconducting substrate s

Abstract: Described herein is an improved process for electroplating a conductive metal layer to the surface of a nonconductive material comprising the following steps:(a) preparing a liquid dispersion of carbon black comprised of:(1) carbon black particles having an average particle diameter of less than about 3.
