ABSTRACT:
A process for electroplating a metal clad substrate by forming a sacrificial coating over the metal cladding and then coating the substrate with a coating of carbonaceous particles. The coating of particles is applied to the substrate from an aqueous dispersion and then the coating is contacted with an etchant for the sacrificial coating to undercut the carbonaceous coating and facilitate its removal from areas where plating is undesired.
