    • An electrophotographic recording material comprises an electrically conductive base material, an optional insulating intermediate layer and a photoconductive layer comprising at least one layer containing an asymmetrically substituted perylene-3,4,9,10-tetracarboxylic acid imide as charge carrier producing compound, a photoconductor as charge transport compound, binder and customary additives. The asymmetrically substituted perylene-3,4,9,10-tetracarboxylic acid imide can, for example, be represented by the formula ##STR1## where R denotes hydrogen, alkyl, hydroxyalky, alkoxyalkyl, aryl or aralkyl and A denotes phenylene, naphthylene or a more highly fused aromatic carbocylic or heterocyclic radical which can each be substituted by halogen, alkyl, cyano or nitro groups. This material is suitable in double-layer arrangement for highly light sensitive systems, and in a single layer for preparing printing forms or printed circuits.
    • 电子照相记录材料包括导电基材,任选的绝缘中间层和光导电层,其包含至少一层含有不对称取代的苝-3,4,9,10-四羧酸酰亚胺作为电荷载体产生化合物,光电导体 作为电荷输送化合物,粘合剂和常规添加剂。 不对称取代的苝-3,4,9,10-四羧酸酰亚胺可以例如由式(I)表示,其中R表示氢,烷基,羟基亚烷基,烷氧基烷基,芳基或芳烷基,A表示亚苯基 ,亚萘基或更高度稠合的芳族碳环或杂环基,其各自可被卤素,烷基,氰基或硝基取代。 该材料适用于高度光敏系统的双层布置,以及用于制备印刷形式或印刷电路的单层。
