Photosensitive multi-layer material and preparation of adhesive layers employed therein

---

Abstract

---

A photosensitive multi-layer material comprising a base and a photosensitive layer which has a polyamide binder and is soluble or dispersible in an alcoholic solvent contains two layers between the base and the photosensitive layer, namely (a) an adhesion-promoting layer, adjacent to the base, which is derived from a polyurethane binder, prepared by reacting a hydroxyl-containing epoxy resin and a polyisocyanate, and a pigment combination in which a white zinc sulfide pigment is the essential constituent, and (b) an adhesive layer, adjacent to the photosensitive layer, which consists of a baked mixture of an alcohol-soluble copolyamide and a melamine-formaldehyde resin.
