A method is provided for electrolytically plating selected surface portions of a substrate by the application of a permanent stop-off coating. The coating comprises a fused mixture of poly(isobutyl methacrylate) and poly(vinyl toluene) resins. Well defined edges are provided between plated and unplated surface areas by the stop-off coating. Moreover, the coating is resistant to attack during plating and is adaptable, as is, for further processing operations after plating.
