ABSTRACT:
A method of selective plating, e.g. of gold on phosphor bronze, includes the steps of printing on the phosphor-bronze a mask which defines the area to be plated, electro-painting the unmasked areas in an electrolytic bath with an epoxy-phenolic paint, stoving the material so that the epoxy coat becomes a strongly adherent and chemically resistant layer, removing the mask produced in the first step in a suitable solvent, leaving the metal to be plated bare, and electro-plating. The epoxy coating may be left in situ or removed.
