Abstract

Abstract Translated from German Für die Herstellung von Druck- und Reliefformen geeignete lichtempfindliche Aufzeichnungsmaterialien mit einer wasserentwickelbaren photopolymerisierbaren reliefbildenden Schicht auf Basis von Polyvinylalkohol/Monomer-Mischungen enthalten in der photopolymerisierbaren reliefbildenden Schicht als Bindemittel ein Polyvinylalkohol-Derivat, weiches erhalten worden ist durch Umsetzung von Polyvinylalkohol mit einem radikalisch polymerisierbare Gruppen enthaltenden Acylierungsmittel in heterogener Phase in einem aprotischen Dispergiermittel mit einem Überschuß an Acylierungsmittel, der mindestens dem 2 molar-fachen des gewünschten Acylierungsgrades entspricht. Photosensitive recording materials suitable for the production of printing and relief forms with a water-developable photopolymerizable relief-forming layer based on polyvinyl alcohol / monomer mixtures contain in the photopolymerizable relief-forming layer as a binder a polyvinyl alcohol derivative which has been obtained by reacting polyvinyl alcohol with a free-radically polymerizable one Group-containing acylating agent in heterogeneous phase in an aprotic dispersant with an excess of acylating agent which corresponds to at least 2 molar times the desired degree of acylation.
