ABSTRACT:
The adhesion of epoxy-resin containing resist compositions to a copper surface, which resist compositions are exposed to actinic radiation, developed and hardened, is enhanced by contacting the copper surface with an N-heterocyclic compound comprising --NH.sub.2 groups and drying the copper surface comprising the N-heterocyclic compound prior to application of the resist. Printed wiring boards produced by a partially additive process can be produced using this adhesion enhancement technique.
