Photoconductive compositions sensitive to both laser light and tungsten halide light

摘要

A photoconductive composition comprises a photoconductor and a sensitizer. The sensitizer has the formula <IMAGE> wherein R represents alkyl; R1 represents H, alkyl or aryl; R2 represents the atoms required to complete a hetero or carboxyclic ring; A- represents an anion; and n represents the valency of the anion. The composition is sensitive to both laser light sources and tungsten light sources and is useful in electrophotographic reproduction.
