ABSTRACT:
A method of depositing a metal on a surface of a substrate is disclosed. The method comprises forming a dielectric coat containing an activating metal species on the surface of the substrate. The coat is then treated with a reviving agent selected from chromic acid and ceric ammonium nitrate to revive the activating metal species to render the coat capable of participating in an electroless metal deposition.
