  • Photoconductor containing a charge transport layer having an arylamine hole transport material
    Patent number: 9411251
    Abstract: Disclosed herein is a photoconductor including a substrate, a photogenerating layer and a charge transport layer. The charge transport layer includes a hole transport molecule of N4,N4?-bis(4-((E)-4,4-diphenylbuta-1,3-dien-1-yl)phenyl)-N4,N4?-di-p-tolyl-[1,1?-biphenyl]-4,4?-diamine and a binder. The weight percent of the charge transport layer includes N4,N4?-bis(4-((E)-4,4-diphenylbuta-1,3-dien-1-yl)phenyl)-N4,N4?-di-p-tolyl-[1,1?-biphenyl]-4,4?-diamine at from about 50 to about 70.

  • Imaging member
    Patent number: 7846629
    Abstract: An imaging member has a crosslinked overcoat layer. The overcoat layer is formed from an overcoat solution comprising a trisilanol polyhedral oligomeric polysilsesquioxane; two crosslinking agents; a hole transport molecule; an acid catalyst; and an alcohol solvent. The overcoat layer provides excellent wear resistance at a low cost.

  • Imaging members
    Patent number: 7344809
    Abstract: An imaging member having a charge transport layer is provided. The charge transport layer includes a plurality of charge transport layers coated from solutions of similar or different compositions or concentrations, wherein the upper or additional transport layer(s) comprise a lower concentration of charge transport compound than the first (bottom) charge transport layer. The charge transport compound included in the first (bottom) charge transport layer may either be the same or different from that included in the additional charge transport layers. The charge transport compound in one or more of the layers is dissolved or molecularly dispersed in an electrically inactive polymer material to form a solid solution. In such a construction, the resulting charge transport layer exhibits enhanced cracking suppression, improves wear resistance, provides excellent imaging member electrical performance, and delivers improved print quality.
