    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: The invention concerns mixture Ia, containing a mixture IIa, consisting of: a) between 1 and 95 wt % of a solid III, preferably a basic solid III, with a primary particle size of between 5 nm and 20 mu m; and b) between 5 and 99 wt % of a polymer composition IV, obtained by the polymerization of: b1) between 5 and 100 wt %, relative to the composition IV, of a condensation product V comprising: alpha ) at least one compound VI which can react with a carboxylic acid or a sulphonic acid or a derivative or a mixture of two or more thereof; and beta ) at least one mol per mol of the compound VI of a carboxylic acid or sulphonic acid VII which comprises at least one radically polymerizable functional group, or a derivative thereof or a mixture of two or more thereof; and b2) between 0 and 95 wt %, relative to the composition IV, of a further compound VIII with an average molecular weight (number average) of at least 5000 with polyether segments in the main or side chain. The portion by weight of mixture IIa in mixture Ia is between 1 and 100 wt %.

    Abstract: A mixture which is crosslinkable by photopolymerisation, is soluble or dispersible in aqueous media and is based on hydroxyl- and/or amido-containing polymers as binders, photopolymerisable monomers which are compatible therewith and photopolymerisation initiators and which contains, based on its total amount, from 0.1 to 10% by weight of an aldehyde of the formula I in which R is a hydrogen atom, a hydroxyl group or a C1-C6-alkyl, C1-C6-alkoxy, C6-C10-aryl or C6-C10-aryloxy radical, can be used in multilayer photosensitive recording materials which can be developed using aqueous media and contain at least one layer of a mixture of this type.

    Abstract: Novel photopolymerizable recording materials, in particular for the production of printing plates and relief plates, can be developed with water or an aqueous alkaline solution and predominantly consist of a photoinitiator-containing mixture of (a) one or more low molecular weight compounds having one or more photopolymerizable olefinically unsaturated double bonds and (b) one or more organic polymeric binders and contain a bisacylphosphine oxide as the photoinitiator. These recording materials are useful for the production of printing plates and relief plates.
