ABSTRACT:
A photoimageable composition includes a polymeric binder which is soluble in aqueous solution; a cross-linking agent for the polymeric binder; a polymerizable acrylic substance; a chemical, photosensitive, free radical-generating initiating system; and a liquid epoxy resin composition and an epoxy cure catalyst. In one method of using the photoimageable composition of the present invention, the composition is applied as a film to a substrate, heated to make the film non-tacky but still aqueous-soluble, exposed to actinic radiation, developed in aqueous solutions to wash away non-exposed portions of the film and heat-cured to harden the film.
