Light-sensitive composition and process

An aqueous developable photoimageable composition comprising a binder and a curing system for components of said binder, said binder comprising an admixture of a phenolic resin and a compound having at least two reactive functionalities selected from the group of an epoxy radical, a vinyl ether radical and a mixture of an epoxy and a vinyl ether radical, and said curing system comprising a crosslinking agent for the phenolic resin and photoactive compound capable of generating a curing catalyst for said binder;

• said phenolic resin being present in an amount sufficient to render unexposed portions of the composition alkali soluble, said compound having at least two reactive functionalities being present in an amount capable of hardening said composition, and said curing system being present in a amount capable of curing the components of the binder upon exposure to activating radiation and baking before development.
