Abstract:
1. A process for preparing an overcoat having low surface energy for an imaging member, the imaging member comprising a substrate, a charge generation layer disposed on the substrate, a charge transport layer disposed on the charge generation layer, and an overcoat layer disposed on the charge transport layer, wherein the process comprises: a) combining a crosslinkable resin comprising a carboxylic acid group, a melamine formaldehyde crosslinking agent, a crosslinkable fluoro additive that contains a crosslinkable group selected from the group consisting of hydroxyl, carboxylic acid, carboxylic ester, sulfonic acid, silane, phosphate, and mixtures thereof, an acid catalyst, N,N′-diphenyl-N,N′-bis(3-hydroxyphenyl)-[1,1′-biphenyl]-4,4′-diamine and a suitable alcoholic solvent to form an overcoat solution; and b) subsequently providing the overcoat solution onto the charge transport layer to form an overcoat layer.
