A CHARGE TRANSFER LAYER WITH HYDRAZONE, ACETOSOL YELLOW AND ANTIOXIDANT OF BUTYLATED P-CRESOL REACTED WITH DICYCLOPENTADIENE

摘要

A photoconductor having a charge transport layer in illustrative embodiments of a polycarbonate binder, 30 to 60 percent by weight DEH hydrazone, o.5 percent to 5 percent acetosol yellow, and 0.5 percent by weight of the butylated reaction product of p-cresol and dicyclopentadiene. The charge generation layer by type IV oxotitanium phthalocyanine in polyvinylbutyral, poly (methyl-phenyl) siloxane and polyhydroxystyrene. Light fatigue is largely eliminated while the physical and cost advantages of DEH are realized.
