Title:
POLYCARBONATE RESIN, COATING LIQUID CONTAINING SAME, AND ELECTROPHOTOGRAPHIC PHOTOSENSITIVE BODY
Document Type and Number:
WIPO Patent Application WO/2010/079698
Kind Code:
A1
Abstract:
Disclosed is a urethane-type polycarbonate resin which utilizes strong hydrogen bonds between urethane groups and has high wear resistance. Specifically disclosed is a polycarbonate resin having a repeating unit represented by general formula [1] and a repeating unit represented by general formula [2]. Also specifically disclosed is an electrophotographic photosensitive body having a photosensitive layer on a conductive substrate, wherein the polycarbonate resin is contained as a component of the photosensitive layer. The electrophotographic photosensitive body has high wear resistance and maintains excellent electrophotographic characteristics for a long time.
(In general formulae [1] and [2], Ar2 represents a group having a divalent aromatic group, and Ar1 represents a divalent aromatic group-containing group having a specific structure.)
