ABSTRACT:
A photoconductive composition useful in electrophotography comprising a mixture of photoconductive zinc oxide, a binder, a first dye which absorbs near infrared radiation and which is effective in sensitizing the zinc oxide to near infrared radiation, and a second dye which absorbs visible radiation, sensitizes zinc oxide to such visible radiation and is effective in enhancing the discharge rate of the sensitized zinc oxide at any given intensity of the near infrared radiation is provided. A paper base sheet coated with such a photoconductive composition can be used in the preparation of an electrophotographic image.
