摘要:
An electrophotographic photoconductor is composed of an electroconductive support and a photoconductive layer formed thereon, which photoconductive layer includes a polycarbonate resin. Aromatic polycarbonate resins not only for the electrophotographic photoconductor, but also for the materials for liquid display panels, optical cards, optical discs, varieties of films having high transparency and heat resistance, deposited plastic reflecting mirrors, and lenses are disclosed.
摘要:
An aromatic polycarbonate containing a structural unit of the formula: ##STR1## wherein R.sup.1 is a hydrogen atom, a substituted or unsubstituted alkyl group or a substituted or unsubstituted aryl group, Ar.sup.1 is a substituted or unsubstituted aryl group and Ar.sup.2 and Ar.sup.3 are independently a substituted or unsubstituted arylene group. The aromatic polycarbonate is capable of transferring charges and is used for forming a photosensitive layer of an electrophotographic photosensitive medium.
