Abstract:
A conductive substrate, particularly a pattern attached to or embedded in an insulating medium and involving nonintegral elements, is galvanically plated by contacting an exposed electrically conductive substrate (preferably in the form of a pattern) with a spray comprising the dissolved salt of a plating metal together with a powdered driving metal which is less noble than either the substrate or the plating metal, said driving metal being mixed with an inert, sprayable, particulate material, thereby resulting in the deposition of said plating metal on said conductive substrate.
