Abstract
An improved organic photoreceptor is disclosed which is coated with a clear polymer film to prevent aromatic amine transport molecule leakage and binder cracking when exposed to liquid toner developers. The polymer film may also be overcoated with a polysiloxane layer to provide additional abrasion resistance.
Claims11
A coated photorecptor element comprising a charge generation layer and a charge transport layer, wherein said charge transport layer comprises an aromatic amine transport molecule, wherein said transport layer is coated with a layer of a transport and conductive emulsion polymer that is unaffected by hydrocarbon solvents and that suppresses leaching of said transport molecule from said transport layer.
A coated photoreceptor element comprising a charge generation layer and a charge transport layer, wherein said charge transport layer comprises N,N'-diphenyl-N,N'-bis(3-methylphenyl)-(1,1'-biphenyl)-4,4'-diamine, wherein said transport layer is coated with a polymer layer comprising a mixture of a crosslinked acrylic emulsion polymer and trimethoxysilyl propyl-N,N,N-trimethyl ammonium chloride, and wherein said polymer layer is coated with an overcoat layer comprising a mixture of a polysiloxane and trimethoxysilyl propyl-N,N,N-trimethyl ammonium chloride.
