Abstract
An electrophotographic photoconductor composed of an electroconductive substrate and a photoconductive layer formed thereon, containing an interpenetrating polymer network prepared by polymerizing a composition composed of a binder resin and at least one polymerizable carbon-carbon double-bond-containing charge transporting monomer selected from the group consisting of monomers of formulas (I), (II) and (III) by the application of light or heat thereto: ##STR1##
Claims19
An electrophotographic photoconductor comprising an electroconductive substrate and a photoconductive layer formed thereon, wherein said photoconductive layer comprises a charge generating material and an interpenetrating polymer network prepared by polymerizing a composition comprising a binder resin and at least one polymerizable carbon-carbon double-bond-containing charge transporting monomer selected from the group consisting of monomers of formulas (I), (II) and (III) by the application of light or heat thereto:
- ##STR107## wherein R.sup.1 is hydrogen or methyl group;
- Ar.sup.1 and Ar.sup.2 each is a bivalent aromatic hydrocarbon group which may have a substituent such as hydrogen, fluorine, chlorine, bromine, iodine, or a straight-chain or branched alkyl group having 1 to 4 carbon atoms which may have a substituent such as fluorine, cyano group or phenyl group;
- Ar.sup.3 and Ar.sup.4 each is a monovalent aromatic hydrocarbon group which may have a substituent such as hydrogen, fluorine, chlorine, bromine, iodine, or a straight-chain or branched alkyl group having 1 to 4 carbon atoms which may have a substituent such as fluorine, cyano group or phenyl group;
- Y is --C.sub.n H.sub.2n --, --CH.dbd.CH--, or --CAr.sup.1 .dbd.CH--;
- Z id --O--, --OC.sub.n H.sub.2n --, or --OC.sub.n H.sub.2n O--;
- n is an integer from 1 to 10;
- and m1 and m2 is an integer of 0 or 1.
