    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 perylene-3,4,9,10-tetracarboxylic acid N,N'-bis-(2',6'-dichlorophenyl)-diimide is employed as the charge carrier-producing dye, and the production of this recording medium.

    Abstract: A description is given of a novel panchromatic electrophotographic recording element, which exhibits an electrically conductive base and at least one photoconductive coating. In this case, the photoconductive coating contains at least one binder, compounds or sensitisers generating a plurality of charge carriers, at least one compound (photoconductor) transporting charge carriers as well as, where appropriate, additives. The sensitisers themselves are Victoria Blue FB (C.I. 44045), Crystal Violet FN (C.I. 42555), Rhodamin FB (C.I. 45170), Astrazon Orange R (C.I. 48040) and/or Astrazon Orange G (C.I. 48035), which are used together with naphtholactam dyes and/or isoindolenine dyes. In this case, the naphtholactam dyes exhibit within the molecule at least one chromophor of the general basic structure and the isoindolenine dyes exhibit within the molecule at least one chromophor of the general basic structure

    Abstract: Production of an electrically conductive surface layer on moulded articles consisting of plastics which are soluble or can be swelled in organic solvents, the conductivity of which surface layer is based on a system embedded therein of… - organic electron acceptors (I) on the one hand and… - organic electron donors (II), iodides (III) or mixtures of (II) and (III) as electron donors on the other hand,… in that the moulded articles are treated with organic solutions of these components. … The products of the process have a surface resistance between 10 and 10 ohms and have the advantage that the other characteristics of the moulded articles are virtually uninfluenced by the means (I) to (III).
