Perylene tetracarboxylic acid imide pigments in an electrophotographic recording material

摘要: An electrophotographic recording material comprises an electrically conductive base material, optional insulating intermediate layer and a photoconductive comprising at least one containing asymmetrically substituted perylene-3,4,9,10-tetracarboxylic acid imide as charge carrier producing compound, photoconductor transport binder customary additives. The can, for example, be represented by the formula ##STR1## where R denotes hydrogen, alkyl, hydroxyalky, alkoxyalkyl, aryl or aralkyl A phenylene, naphthylene more highly fused aromatic carbocylic heterocyclic radical which can each halogen, cyano nitro groups. This is suitable in double-layer arrangement light sensitive systems, single preparing printing forms printed circuits.
