Abstract
Photoconductive composition comprising an insulating polymeric matrix and a compound of the formula ##STR1## wherein R is hydrogen or nitrile; and R', R' and R'' are independently selected from an aliphatic hydrocarbon radical having from about 1 to about 10 carbon atoms; phenyl; or substituted phenyl, said phenyl substituents being capable of releasing electrons to relatively electron deficient centers within the compound; amino; diarylamino; dialkylamino or alkoxy; and n can range from 0 up to the potential number of positions of substitution on the aromatic ring system. These compositions have good spectral response in the visible region of the electromagnetic spectrum and are suitable for use in electrostatographic imaging members and methods.
