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 (sensitizers), and compounds which are charge carrier-transporting when exposed to light, possess high photoconductivity and low conductivity in the dark, and contain, as charge carrier-transporting compounds, 1,2,3-triazoles of the fomula (I) are used for reprographic purposes and for the production of electrophotographic printing plates, in particular offset printing plates.

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.
