ABSTRACT:
Metallic surfaces are imparted to non-conductive or dielectric substrates by an electroless coating process comprising coating the surface of the substrate with a hydrous oxide colloid of non-precious metal ions preferably selected from the group consisting of cobalt, nickel and copper ions, reducing the selected metal ions to a reduced or zero valence state with a suitable reducing agent, and exposing the substrate to an electroless plating bath.
