ABSTRACT:
A relief printing plate whose photopolymerized relief layer has a non-tacky surface is produced by (1) imagewise exposure of a photopolymerizable relief-forming recording layer which contains one or more polymeric binders containing acid groups, (2) washing out (development) of the unexposed and therefore non-photopolymerized parts of the imagewise exposed relief-forming recording layer with a developer and (3) aftertreatment of the resulting photopolymerized relief layer with a basic aftertreatment solution.
