ABSTRACT:
The present invention provides a method for making a metallic pattern on a substrate having a surface comprising bare metal in predetermined areas and metal coated by a resist in remaining areas which comprises (i) protecting the bare metal by electrodepositing a resin thereon, (ii) while leaving the electrodeposited resin substantially uncured, removing the resist from said remaining areas using a solvent which will not remove the electrodeposited resin, thereby exposing metal in said remaining areas, (iii) etching the metal exposed in (ii) using an etchant which does not remove the electrodeposited resin, and (iv) removing the electrodeposited resin with a suitable solvent.
