Abstract: Multilayer, electrophotographic recording material having… (A) an electrically conductive substrate and having… (B) one or more layer(s) of… (b1) one or more binder(s),… (b2) one or more charge carrier-producing compound(s) or sensitisers,… (b3) one or more charge carrier-transporting compound(s) or photoconductors and, if required,… (b4) additives,… wherein the charge carrier-producing compounds or sensitisers (b2) used are naphtholactam dyes of the general formula I … … in which the indices and the variables have the meaning described in the Claims and in the description, and novel naphtholactam dyes of the general formula I, in which the radical R is a substituted, monocyclic 1,3-thiazolyl radical bonded via a ring carbon atom to the naphtholactam skeleton, the use of these novel naphtholactams I in electrophotographic and laser-optical recording materials and novel reprographic methods and novel processes for the production of offset printing plates and of photoresists, in which the novel multilayer, electrophotographic recording material is used.

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: A process for preparing mono- or poly-C1-C20-alkyl- and/or -halogen-substituted arylcarbonyl chlorides (I), by, in a first stage, reacting a mono- or poly-C1-C20-alkyl- and/or -halogen-substituted aromatic (II) with CCl4 in the presence of a Friedel-Crafts catalyst to give the corresponding mono- or poly-C1-C20-alkyl- and/or -halogen-substituted trichloromethylated aromatic (III), and, in a second stage, treating the trichloromethylated aromatic (III) with water or a protic acid in the presence of a catalyst to obtain the arylcarbonyl chloride (I). In a particularly preferred embodiment, the trichloromethylated aromatic (III) is not isolated as an intermediate and is used in the second stage dissolved in the solvent of the first stage.
