  • Charge transfer layer with hydrazone, acetosol yellow and antioxidant of butylated p-cresol reacted with dicyclopentadiene
    Publication number: 20020122998
    Abstract: A photoconductor having a charge transport layer in illustrative embodiments of a polycarbonate binder, 30 to 60 percent by weight DEH hydrazone, 0.5 percent to 5 percent acetosol yellow, and 0.5 percent to 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.
