Abstract
A photoconductive recording material having a conducting electrode element coated with one or more layers, one or more of said layers incorporating one or more polyester carbonate copolymers, wherein the aromatic carbonate units are present in the range of 10 to 48 mole % of said copolymer and correspond to the general formulae (I), and wherein the aromatic ester units are present in the range of 52 to 90 mole % of said copolymer and have one or more of the compositions represented by the general formulae (II and III) described herein.
Claims12
A photoconductive recording material having a conducting electrode coated with at least one binder layer incorporating at least one polyester carbonate copolymer containing aromatic polyester and aromatic carbonate units and wherein the aromatic carbonate units are present in the range of 10 to 48 mole % of said copolymer and correspond to the following general formula (I):
- ##STR13## each of R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.7 and R.sup.8 (same or different) represents hydrogen, halogen, an alkyl group or an aryl group, and each of R.sup.5 and R.sup.6 (same or different) represents hydrogen, an alkyl group, an aryl group or together represent the necessary atoms to close a cycloaliphatic ring, and wherein the aromatic ester units are present in the range of 52 to 90 mole % of said copolymer and have at least one of the compositions represented by the general formulae (II and III):
- ##STR14## in which:
- X, R.sup.1, R.sup.2, R.sup.3 and R.sup.4 have the same meaning as described above, said polyester carbonate having a weight averaged molecular weight in the range of 120,000 to 1,000,000.
