Claims19
A photoconductor comprising:
- a substrate
- an undercoat layer comprising a metal oxide, and a mixture of a phenolic resin and a cycloheaxanecarboxylate disposed on the substrate;
- a photogenerating layer;
- and
- a charge transport layer.
A photoconductor comprising a supporting substrate, an undercoat layer thereover comprised of a mixture of a metal oxide, a phenolic polymer and a cyclohexanecarboxylate;
- a photogenerating layer, and a charge transport layer, and wherein said phenolic resin is present in an amount of from about 20 weight percent to about 80 weight percent, said cyclohexancarboxylate is present in an amount of from about 1 weight percent to about 30 weight percent, and wherein said metal oxide is present in an amount of from about 20 weight percent to about 80 weight percent, and wherein the total of said components in said undercoat layer is about 100 percent.
A photoconductor comprised in sequence of a supporting substrate, a hole blocking layer thereover comprised of a mixture of a metal oxide, a phenolic formaldehyde resin, and a cyclohexanecarboxylate represented by
- wherein R is an alkyl having from about 1 carbon atom to about 18 carbon atoms, and n is from about 1 to about 6;
- a photogenerating layer, and a hole transport layer;
- wherein the phenolic formaldehyde resin is selected from the group consisting of the reaction products of p-tert-butylphenol, cresol, and formaldehyde;
- 4,4′-(1-methylethylidene)bisphenol and formaldehyde;
- phenol, cresol, and formaldehyde;
- phenol, p-tert-butylphenol and formaldehyde;
- and mixtures thereof;
- the metal oxide is selected from the group consisting of titanium oxide, titanium dioxide, zinc oxide, tin oxide, aluminum oxide, silicone oxide, zirconium oxide, indium oxide, and molybdenum oxide;
- the photogenerating layer is comprised of a photogenerating pigment and a resin binder;
- and the hole transport layer is comprised of aryl amine molecules and a resin binder.
