CA 2551441
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.
Le présent brevet porte sur une couche de finition de silicone constituée d'une composition de polysiloxane réticulée faite d'un segment de perfluoropolyéther. La composition de polysiloxane est le produit de l'hydrolyse et de la condensation d'une formulation de couche de finition de silicone constituée d'un composé de perfluoropolyéther, d'un composé aromatique contenant de la silicone et d'un composé de transport de trou contenant de la silicone. Un élément d'imagerie électrophotographique pourvu d'une telle couche offre des propriétés améliorées.
