ABSTRACT:
A novel panchromatic electrophotographic recording element has an electrically conducting substrate and one or more photoconducting layers. The photoconducting layer contains one or more binders, several charge carrier-producing compounds or sensitizers, one or more charge carrier-transporting compounds (photoconductors) and, if required, additives. The sensitizers themselves are Victoria Blue FB (C.I. 44045), Crystal Violet FN (C.I. 42555), Rhodamine FB (C.I. 45170), Astrazone Orange R (C.I. 48040) and/or Astrazone Orange G (C.I. 48035), which are used together with naphtholactam dyes and/or with isoindolenine dyes. The naphtholactam dyes have one or more chromophores of the general basic structure ##STR1## in the molecule, and the isoindolenine dyes have one or more chromophores of the general basic structure ##STR2## in the molecule.
