Abstract: The invention relates to photopolymerisable printing plates suitable for producing soft-elastic printing formes. These carry, on a dimensionally stable carrier, at least one interlayer and, on top thereof, a photopolymerisable layer which essentially consists of a mixture of a water-soluble copolymer or derivative of polyvinyl alcohol, a defined copolymerisable monofunctional (meth)acrylate, a photoinitiator and a thermal polymerisation inhibitor.

Abstract: Process for the production of a relief printing plate whose photopolymerised relief layer has a nontacky surface by (1) exposing, through an image, a photopolymerisable relief-forming recording layer which contains at least one polymeric binder containing acid groups, (2) washing out (developing) the unexposed, and therefore unphotopolymerised regions of the relief-forming recording layer exposed through an image with a developer solvent, and (3) posttreatment of the resultant photopolymerised relief layer with a basic posttreatment solution.
