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: Process for anodising the surface of plates, foils or strips made of aluminium or aluminium alloys in an aqueous electrolyte which contains one or more acids and also, optionally, one or more additives and which contains, as additive or as one of the additives or as acid or as one of the acids, a silane or a plurality of silanes of the general formula I where the indices and the variables have the following meaning: y is an integer from 1 to 4; n is 0, 1 and 2 independently of y; R and R are C1-C9-alkyl and C6-C12-aryl, R and R being identical to, or different from, each other; and X is the radicals X to X , where the variables have the following meaning: R is a hydrogen atom, C1-C9-alkyl, an alkane-carboxylic anhydride ring formed from the alkanecarboxylic acid radical containing 1 to 9 carbons atoms and a carboxylic acid group linked to R3 R and R are the radical R ; R is a hydrogen atom and the radical R ; Z is a hydrogen atom and an alkali metal cation; Ar is C6-C12-arylene; and Hal is a chlorine and bromime atom; the silanes of the general formula I (= silanes I) being dissolved in the electrolyte solution in hydrolysed and/or condensed form. Also the use of the plates, foils or strips made of aluminium or aluminium alloy anodised by this process for producing bases for photosensitive lithographic printing plates or offset printing plates.

Abstract: Un proceso para preparar un sistema de polímero de color, que está compuesto de una matriz y unas partículas de polímero discretas distribuidas de acuerdo con una estructura de red espacial definida en la matriz, y que se obtiene al laminar un polímero de emulsión con una estructura de núcleo/corteza, que comprende - utilizar un polímero de emulsión obtenible al - polimerizar monómeros en al menos una primera etapa (monómeros de núcleo), - luego polimerizar los monómeros en al menos una segunda etapa adicional (etapa de transición), y - finalmente polimerizar los monómeros en una tercera etapa (monómeros de corteza), en donde, basado en el porcentaje de constitución de la mezclas de monómero de las tres etapas, a lo sumo el 30% en peso de los monómeros de la primera etapa son idénticos a aquellos de la tercera etapa, y el 5% de los monómeros de la segunda etapa son idénticos con, respectivamente, aquellos de la primera y aquellos de la tercera etapa, y no más del 60% en peso de los monómeros de la segunda etapa aquí son monómeros ausentasen la primera etapa y también ausentes en la tercera etapa.

Abstract: Aqueous alkenylsuccinic anhydride-containing polymer dispersions which are obtainable by miniemulsion polymerization of hydrophobic monoethylenically unsaturated monomers in the presence of alkenylsuccinic anhydrides, processes for the preparation of such polymer dispersions by polymerizing hydrophobic monomers by a miniemulsion polymerization method in the presence of at least one alkenylsuccinic anhydride and, if appropriate, an alkyldiketene, and use of the resulting aqueous alkenylsuccinic anhydride-containing polymer dispersions as engine and surface sizes for paper and for imparting water repellency to leather, natural and/or synthetic fibers and textiles.
