ABSTRACT:
Metallic surfaces are imparted to non-conductive or dielectric substrates by an electroless (chemical) coating process comprised of coating the surface of the substrate with colloids of catalytic non-precious metals wherein the metals are either part of an alloy or in the elemental state or a compound and wherein the colloidal compositions are prepared by a special method which renders the colloids a greater catalytic activity when used in the plating process.
