Abstract

In a photosensitive recording material comprising PA0 (A) a photopolymerizable relief-forming layer which can be developed with liquid developer after imagewise exposure to actinic light, PA0 (B) a top layer which consists of polymers forming films of high tensile strength, adheres firmly to the photopolymerizable relief-forming layer (A) and is soluble or swellable in the liquid developers and PA0 (C) a cover sheet which can readily be peeled off from the top layer (B), the top layer (B) contains specific tertiary amines and/or amides and/or specific quaternary ammonium salts of the type defined in more detail in the claims. Photopolymerized printing plates, relief plates or photoresists are produced by a process in which this recording material is used.
