Abstract

A photosensitive recording element comprises (A) a dimensionally stable substrate, (B) a photopolymerizable relief-forming recording layer and, if required, an adhesion-promoting layer arranged between (A) and (B), a release layer (C) applied to that side of the recording layer (B) which faces away from the substrate (A), and, if required, a cover sheet (D) applied thereon, the photopolymerizable relief-forming recording layer (B) containing b.sub.1) at least one polymeric binder, b.sub.2) at least one photopolymerizable olefinically unsaturated monomer which is compatible with b.sub.1), b.sub.3) at least one photopolymerization initiator and b.sub.4) at least one aryl alkyl ketone, and is suitable for the production of relief printing plates.
