ABSTRACT:
This invention is directed to a non-flammable plating resist with improved adhesion and edge covering characteristics which permits its selective removal by an ordinary laser ablation process or an energy efficient laser assisted process, and to the preferred method in using same to selectively plate a metal substrate, such as a nickel plated, electrically conductive metal with a precious metal. The preferred method comprises the steps of applying a thin uniform layer of such resist onto the substrate and drying the same in situ to a thickness greater than 100 microinches and less than 500 microinches, and drying same in situ, where such resist (a) is resistant to deterioration by chemical plating solutions of such precious metal, (b) is readily strippable in alkaline solutions, and (c) has a flashpoint in excess of 100.degree. F. A preferred formulation for such resist comprises, by weight, the following:
