MULTI-ACTIVE PHOTOCONDUCTIVE INSULATING ELEMENTS EXHIBITING VERY HIGH ELECTROPHOTOGRAPHlC SPEED AND PANCHROMATIC SENSITIVITY AND METHOD FOR THEIR MANUFACTURE ABSTRACT OF THE DISCLOSURE Multi-active photoconductive insulating elements which exhibit very high electrophotographic speed and panchromatic sensitivity, and whose manufacture can be effectively controlled to provide an electrical contrast ranging from a very low to a very high level, are comprised of a charge- generation layer and a charge-transport layer in electrical contact therewith and contain, as the charge-generating agent within the charge-generation layer, certain crystalline forms of N,N'-bis(2-phenethyl)perylene-3,4:9,10-bis(dicar- boximide) characterized by particular spectral absorption and X-ray diffraction characteristics. the charge-generation layer is capable, upon exposure to activating radiation, of highly effective generation and injection of charge carriers and the charge-transport layer, which is comprised of an organic composition containing an organic photoconductive material, is capable of accepting and transporting the injected charge carriers to thereby form a highly advantageous multi-active photoconductive insulating element.
