摘要:
There are provided symmetrical dimeric perylenes of the following formula wherein R is hydrogen, alkyl, cycloalkyl, oxaalkyl, substituted alkyl, aryl, substituted aryl, aralkyl or substituted aralkyl, and X is the symmetrical bridging moiety, N-N, alkylene, when n is zero, substituted alkylene, cycloalkylene, arylene, substituted arylene, aralkylene, or substituted aralkylene.
There are also provided photoconductive imaging members comprised of the perylenes in a charge generator layer.
摘要:
A photoconductive imaging member comprised of a substrate, a photogenerating layer, and thereover a charge transport layer comprised of a charge transport component or components, a polymer binder and metal oxide particles, wherein said metal oxide particles contain or are attached with or to a silane or a siloxane, or alternatively a polytetrafluoroethylene.
摘要:
A silicone overcoat (SOC) layer having a crosslinked polysiloxane composition comprising a perfluoropolyether segment are disclosed. The polysiloxane composition is the product of the hydrolysis and condensation of a SOC formulation comprising a perfluoropolyether compound, an aromatic silicon-containing compound, and a silicon-containing hole transport compound. An electrophotographic imaging member having such a SOC layer has improved properties.
