Abstract

1. An electrophotographic recording material, consisting of an electrically conductive layer support, in particular a support suitable for the manufacture of printing forms or printed circuits, and of a photoconductive layer comprising an organic photoconductor, an alkali-soluble binder, a sensitizing dyestuff, which comprises a cyanine dyestuff absorbing between 400 and 550 nm, and conventional additives, whereby the photoconductor represents a compound of the general formula see diagramm : EP0031481,P5,F1 in which R1 denotes hydrogen, alkyl, alkoxy having 1 to 4 C atoms, halogen or dialkylamino having 1 to 4 C atoms, R2 denotes dialkylamino having 1 to 4 C atoms, and X denotes nitrogen or -CR3 with R3 being phenyl which is optionally substituted by halogen, alkylamino or dialkylamino groups or alkyl having 1 to 4 C atoms, characterized in that the sensitizing dyestuff furthermore comprises an aminoxanthene dyestuff absorbing between 450 and 600 nm.
