Abstract
A process for patterned electroplating involves the steps of: (i) coating a substrate with a layer of amninoalkylpyridine which acts as an adhesion promoter; (ii) coating the adhesion layer with a radiation sensitive polymeric resist; (iii) imagewise exposing the film to radiation; (iv) developing the image to patternwise expose the substrate; (v) electroplating metal onto the exposed portions of the substrate; and (vi) removing the remaining polymeric film from the substrate.
