ABSTRACT:
Material useful in electropolymerization processes comprises a conductive support and a layer thereon of a composition comprising a polymerizable monomer and polymerization catalyst precursor which is a combination of an alkali metal nitrite and a primary aromatic amine. Electrolysis of the composition results in diazotization of the amine with subsequent electrolytic generation of polymerization-inducing free radicals. The anodic reaction ensures polymerization at and bonding of the resulting polymer to the support sheet of the material even when used in conjunction with zinc oxide photoconductor cathode layers. The material is particularly useful in negative-working imagery and in the preparation of patterned resist layers.
