Abstract: An electrophotographic recording material contains, as charge carrier-transporting compounds in the photoconductor layer, a mixture of one or more compounds of the formula (I) and one or more compounds of the formula (II) in a ratio of from 9:1 to 0.6:1, preferably from 2.3:1 to 0.8:1. In the formulae, R1 and R2 independently of one another are each alkyl, allyl, phenylalkyl or unsubstituted or substituted phenyl, R3 and R4 independently of one another are each hydrogen, alkyl, alkoxy or halogen, and R6, R7, R8 and R9 independently of one another are each alkyl, phenylalkyl or cyclohexyl. When the mixture of (I) and (II) is present in an appropriate concentration, the recording materials are highly photosensitive, although the problems usually encounted in the case of high concentrations of charge carrier-transporting compounds do not arise.

Abstract: An electrophotographic recording medium which consists essentially of an electrically conductive base and a photosemiconductive double layer which comprises a first layer containing charge carrier-producing dyes, and a second layer containing one or more compounds which are charge carrier-transporting when exposed to light, wherein the charge carrier-producing dyes are those of the general formula I I where R1, R2, R3 and R4 are each hydrogen or a non-ionic substituent, X and Y are each the radical of a methylene-active compound, or of an aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic amine or hydrazine, and Z is hydrogen, methyl or phenyl, and the production of this recording medium.

Abstract: Electrophotographic recording materials which comprise an electrically conductive base, charge carrier-producing compounds or sensitizers, charge carrier-transporting compounds and added metal-1,3-diketone complexes and possess high photosensitivity and low conductivity in the dark are used for reprographic purposes and for the production of electrophotographic printing plates, in particular offset printing plates.

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: A laminate suitable for the production of printing plates and relief plates, and possessing a photosensitive layer, which is soluble in water or in an aqueous solution, and contains a hydrophilic polymeric binder, applied to a base, contains, between the base and the photosensitive layer, an intermediate layer which consists of a mixture of a polymeric binder compatible with the polymeric binder of the photosensitive layer, and a diacrylate or dimethacrylate monomer which contains urethane groups and is obtained by reacting a hydroxyalkyl acrylate or hydroxyalkyl methacrylate with a diisocyanate. After application to the base, the intermediate layer is cured at 110 DEG -220 DEG C. before the photosensitive layer is applied.
