Reusable, positive-charging organic photoconductor containing phthalocyanine pigment, hydroxy binder and silicon stabilizer

Claim 1

An organic photoconductor for positive charging, said photoconductor having improved surface release characteristics, and comprising: a conductive substrate component; a water insoluble hydroxy-containing binder component forming a layer greater than or equal to about 1 micron thick on said substrate; a phthalocyanine pigment component having the general structure: M--PcX.sub.n (A) where M=hydrogen (metal free), Cu, Mg, Zn, TiO, VO, InY (Y=halogen, Cl, Br, l, F) X=halogen (Cl, Br, l, F), nitro --NO 2 , cyano--CN, sulfonyl --SO 2 alkyl, alkoxy, and N=0-4, said phthalocyanine pigment being uniformly distributed throughout said binder component; a reactive stabilizer component selected from the group of polysiloxanes, organo-silane compounds and porous fillers containing silicon atoms, said reactive stabilizer component also being uniformly distributed throughout said binder component; and, said photoconductor being prepared by a curing process which includes thermal curing, moisture or hydrolysis curing, and radiation curing, the latter including UV, X-ray and electron beam curing.
