Patent ID: 8603710

Claim:
A flexible imaging member comprising: a flexible electrically conductive substrate; a charge generating layer disposed on the substrate; a charge transporting layer disposed on the charge generating layer; and an anti-curl back coating disposed on the substrate on a side opposite to the charge transport layer, the anti-curl back coating comprising a copolymer of Formula I: wherein Block A has the following structure: Block B has the following structure: R 1 is H or CH 3 ; each R 2 , R 3 is independently H or lower C 1 -C 3 alkyl, or R 2 and R 3 taken together with the C atom to which they are attached form an alkylcyclic ring, where any ring atom of the alkylcyclic ring may be optionally substituted with an alkyl; each R 4 , R 5 is independently H or lower C 1 -C 3 alkyl, or R 4 and R 5 taken together with the C atom to which they are attached form an alkylcyclic ring, where any ring atom of the alkylcyclic ring may be optionally substituted with an alkyl; each R 7 , R 8 , R 9 , R 10 is independently H or lower C 1 -C 3 alkyl; W is an aryl or alkylene having from 2 carbon atoms to 10 carbon atoms; y is between about 1 and about 6; z is between about 9 and about 18; and n is between about 20 and about 80.
