Abstract
A method for electroplating a nonconducting surface using a metal oxide colloid. The process comprises contacting the surface of the nonconductor to be plated with a preformed colloid of a metal oxide to adsorb the colloid onto the surface of the nonconductor and then electroplating metal over the surface having the adsorbed metal oxide colloid. The process may include a step of reducing the metal oxide to a lower valent state prior to the step of metal plating.
