Hydrazone and pyrazoline or acetosol yellow containing charge transport layer, photoconductor and electrophotographic process using the same

In an electrophotographic element comprising:

• an electrically conductive layer;
• a charge generation layer responsive to actinic radiation to generate an electron-hole pair;
• and
• a p-type charge transport layer adjacent the charge generation layer, the charge transport layer comprising a hydrazone of the composition p-diethylaminobenzaldehyde(diphenylhydrazone), i.e.:
• ##STR4## and a polymeric binder;
• whereby holes generated by photoelectric phenomenon in the charge generation layer may be transported through the charge transport layer to facilitate localized selective discharge of charged surfaces of the element, the improvement comprising:
• the addition of [DEASP or Acetosol Yellow] 1-phenyl-3[p-diethylaminostyryl]-5-[p-diethylaminophenyl]-pyrazoline to said charge transport layer in an amount which is effective to produce the result that the photosensitivity of the photoconductor is not appreciably affected by exposure to limited amounts of ambient light.
