Abstract:
An electrophotographic imaging member, comprising:a substrate;an undercoating layer formed over the substrate; anda photosensitive layer formed over the undercoating layer;wherein the undercoating layer is derived from crosslinking a silyl-functionalyzed hydroxyalkyl acrylate or methacrylate polymer (I) with a silane coupling agent (I) and optionally a silane coupling agent (II) and optionally in the presence of a crosslinking agent(RO).sub.3 Si--A--Si(OR).sub.3 (I)##STR9##wherein:R is selected from the group consisting of alkyl, substituted alkyl, aryl, substituted aryl, and acyl groups, each having from about 1 to 24 carbon atoms;A is a divalent linkage;X is selected from the group consisting of an alkyl, a substituted alkyl, an aryl, and a substituted aryl group;R.sup.1, R.sup.2, and R.sup.3 are independently selected from the group consisting of an alkyl, an aryl, an alkoxy, an aryloxy, an acyloxy, a halide, a cyano, and an amino group, provided that at least two of the R.sup.1, R.sup.2, and R.sup.3 are selected from the group consisting of alkoxy, aryloxy, acyloxy, halide, cyano, and amino groups;R.sup.4, R.sup.5, and R.sup.6 are selected from the group consisting of hydrogen and an alkyl group;Z is a hydrolyzable functional group;B is selected from the group consisting of halide, cyano, aryl, alkoxycarbonyl and aryloxycarbonyl groups;D is a divalent linkage selected from the group consisting of alkyleneoxycarbonyl, arylene, alkylenearyl, aryleneoxycarbonyl, and alkylenearyloxycarbonyl;E is a divalent linkage selected from the group consisting of alkyleneoxycarbonyl, and alkylenearyloxycarbonyl; anda, b, and c are the mole fractions of the repeating units of the polymer, such that a+b+c=1.
