Abstract

Abstract A process for metalizing a non-conductive substrate wherein the substrate is coated with an organic polymer-carbon black mixture, having a volume resistivity of less than about 1,000 ohmcentimeters, the surface of the mixture is caused to contain sulfur and the thus treated substrate is placed as a cathode in a nickel, cobalt or iron plating bath to cause a rapid spread of metal across the thus treated surface.
