Abstract
Photoconductive compositions comprising an insulating polymeric matrix and a compound of the formula ##STR1## wherein R is --H or --CN; PA1 R', r", r'" and R.sup.iv are independently selected from an aliphatic hydrocarbon radical having from about 1 - 10 carbon atoms; phenyl; or substituted phenyl wherein said substituents are capable of releasing electrons to relatively electron deficient centers within the compound; amino; diarylamino; dialkylamino or alkoxy; 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.
