Abstract
An electrophotographic imaging member includes a supporting substrate, an undercoating layer, an optional adhesive layer, a photogenerating layer, and a charge transporting layer. The undercoating layer is derived from the reaction of a silyl-functionalyzed polymer (III) with a silane coupling agent (I) and an optional silane coupling agent (II): EQU (RO).sub.3 Si--A--Si(OR).sub.3 (I) ##STR1## where R is alkyl, substituted alkyl, aryl, or substituted aryl, acyl, and the like; A is selected from alkylene, arylene, and alkylenearyl; X is alkyl, substituted alkyl, aryl, or substituted aryl; R.sup.1, R.sup.2, and R.sup.3 are independently selected from alkyl aryl, alkoxy, aryloxy, acyloxy, halide, cyano, amino, and the like; R.sup.4, R.sup.5, and R.sup.6 are hydrogen and alkyl; Z is selected from chloride, bromide, iodine, cyano, alkoxy, and acyloxy; B is preferably selected from halide, cyano, aryl, alkoxycarbonyl, aryloxycarbonyl and the like; D and E are preferably selected from alkyleneoxycarbonyl, arylene, alkylenearyl, aryleneoxycarbonyl, and alkylenearyloxycarbonyl; a, b, and c are the mole fractions of the repeating units of the polymer such that a+b+c=1.
