ABSTRACT:
Polymeric photoconductors are disclosed comprising a condensation polymer backbone containing, as repeating units, the condensation residues of (1) a diacid, and (2) an organic difunctional compound capable of undergoing condensation polymerization with said diacid, and an arylamine photoconductor group appended to at least one of said diacid or said organic difunctional compound residues.
A preferred polymeric photoconductor is ionic and comprises a condensation copolymer containing, in addition to the above described repeating units, the condensation residue of a second diacid containing an anionic iminodisulfonyl or sulfo group. In certain embodiments, the ionic arylamine-containing polymers are water-dispersible copolyesters.
The polymeric photoconductors described are useful in photoconductive compositions and elements. Electrophotographic processes employing such elements are also disclosed.
