Abstract

Abstract Translated from German In wäßrigen Lösungsmitteln entwickelbare photoempfindliche Aufzeichnungs­materialien mit a) einem polymeren Bindemittel, b) Photoinitiator und c) bevorzugt zusätzlichen verträglichen photopolymerisierbaren Monomeren enthalten als polymere Bindemittel ein bevorzugt in Wasser lösliches Polyalkylenoxid-Vinylester-Pfropfcopolymerisat, das verseift oder teil­verseift und gegebenenfalls danach teilverestert oder umgeestert wurde und die Alkylenoxid-, gepfropften Alkylenoxid-, Vinylalkohol- und Vinyl­ester-Struktureinheiten in bestimmten Mengen und Verhältnissen enthält. Die elastomeren Pfropfcopolymerisate und damit hergestellten Aufzeich­nungsmaterialien dienen zur Herstellung von Reliefformen, insbesondere Druckformen für den Flexodruck. Photosensitive recording materials which can be developed in aqueous solvents and which contain a) a polymeric binder, b) photoinitiator and c) preferably additional compatible photopolymerizable monomers contain, as polymeric binders, a preferably water-soluble polyalkylene oxide / vinyl ester graft copolymer which has been saponified or partially saponified and, if appropriate, then partially esterified or transesterified and containing the alkylene oxide, grafted alkylene oxide, vinyl alcohol and vinyl ester structural units in certain amounts and ratios. The elastomeric graft copolymers and recording materials produced therewith are used for the production of relief forms, in particular printing forms for flexographic printing.
