ABSTRACT:
A method for sensitizing a substrate of non-conductive material for the deposition thereon of a conductive film of copper or nickel comprises the steps of applying to the substrate a substance which can photochemically abstract a hydrogen atom from a hydrogen donor in the presence of a suitable solvent, and subsequently immersing the sensitized substrate in a solution containing certain metal ions such as copper, nickel or silver, and simultaneously exposing the sensitized substrate to radiation from an ultraviolet light source.
