  • Patent number: 6194111
    Abstract: A crosslinkable charge transport layer material for a photoconductor includes at least one poly(arylene ether alcohol), at least one polyisocyanate crosslinking agent and at least one charge transport material dispersed in a solvent. The crosslinkable charge transport layer material is crosslinked following application of the coating solution to the photoconductor. The photoconductor including such crosslinked charge transport layer exhibits excellent wear resistance so as to have long life, thereby reducing the cost of electrophotographic printing machines employing such photoconductors therein.
