ABSTRACT:
A radiation sensitive composition, process for using said composition, and substrates coated with said composition. The photoimageable composition comprises a photobase generator compound, a resin binder and a material capable of crosslinking in the presence of base. In preferred aspects, the invention provides a negative-acting, aqueous developable photoimageable composition comprising a photobase generator compound, a resin binder which preferably is a phenolic polymer, a crosslinking agent that comprises one or more active groups that will undergo base-initiated crosslinking, and a curing agent.
