摘要:
A photoconductive imaging member comprised of a photogenerating layer, and a charge transport layer containing a binder and a fluoropolymer generated by the free radical polymerization of a fluoroalkyl(methyl)acrylate and an alkyl(methyl)acrylate.
摘要:
A charge transport layer for an imaging member comprising a charge transport material with a nitrogen molecular defense system not exhibiting early onset of charge transport layer fatigue cracking. The nitrogen molecular defense system includes attaching bulky organic groups to charge transport materials. The bulky groups aid in preventing recrystallization of the charge transport molecule and shield the nitrogen from molecular attack, such as by oxidation. The charge transport layer exhibits excellent wear resistance, excellent electrical performance, and outstanding print quality.

摘要:
A photoconductive imaging member containing a supporting substrate, a photogenerating layer, a charge transport layer, and in contact with the charge transport layer a layer comprised of a polymer and a yellow dye of the formula
摘要:
A composition is provided for coating a photoreceptor having a charge generating layer and a charge transport layer. The composition includes a hole transport material, a cross-linkable film forming binder having at least one functional group that is reactive with isocyanate, a blocked isocyanate cross-linking agent and a solvent having a boiling point equal to or below the deblocking temperature. The blocked isocyanate cross-linking agent is the reaction product of an isocyanate and a blocking agent, wherein the blocking agent has a boiling point temperature equal to or below a selected deblocking temperature to allow the isocyanate to form cross-links. The invention also provides an electrophotographic imaging member with an overcoat layer comprising a cross-linked film forming binder, an isocyanate compound, a hole transport material, and optionally a surface energy reducing agent. Processes for making the imaging members are also provided.
