Abstract (en)

[origin: US4252880A] This invention relates to an improvement in an electrophotographic recording material comprising an electrically conductive support, in particular a support adapted for the preparation of printing forms or printed circuits, and a panchromatically sensitized photoconductive layer which comprises an organic photoconductor, a binder, a sensitizing dye, and conventional additives, the improvement that the photoconductive layer contains, as the sensitizing dye, a mixture of a polymethine dye and a triarylmethane dye which absorb, respectively, between about 400 and 550 nm and between about 550 nm and 720 nm.
