Abstract: A photopolymerizable recording composition which comprises a mixture, containing a photoinitiator, of (a) a photopolymerizable olefinically unsaturated monomer and (b) an organic polymeric binder, wherein the photoinitiator is an acylphosphine oxide compound of the formula R1R2PO-CO-R3, where R1 and R2 are certain organic radicals and R3 is tert.-alkyl or a cyclic radical with two substituents in the ortho-position to the carbonyl group. The recording compositions have a high reactivity when irradiated with UV light and are used in particular for the preparation of printing plates, relief plates and photo-resists.

Abstract: Photosensitive recording materials which are suitable for the production of printing plates and relief plates and possess a photopolymerizable relief-forming layer which can be developed with water and is based on a polyvinylalcohol/monomer mixture contain, as a binder in the said layer, a polyvinylalcohol derivative which is obtained by reacting polyvinylalcohol with an acylating agent which has groups which are polymerizable by free radicals, the reaction being carried out in the heterogeneous phase, in an aprotic dispersant, using the acylating agent in an amount which corresponds to not less than twice the molar amount required to achieve the desired degree of acylation.
