Abstract

A conductive polymer composition selected from the group consisting of PA1 a first composition including PA2 a polymer containing halomethylated aromatic groups, and PA2 a charge transporting material selected from the group consisting of PA3 at least one charge transport monomer containing arylamine groups, PA3 at least one charge transport polymer containing arylamine units in the main polymer chain, PA3 and mixtures thereof, and PA1 a second composition including PA2 at least one monomer containing a halomethylated aromatic group, PA2 at least one charge transport monomer containing arylamine groups and PA2 a polymer binder, and PA1 a third composition including: PA2 at least one monomer containing a halomethylated aromatic group, and PA2 at least one charge transport polymer with arylamine units in the main polymer chain. The aforementioned compositions may be applied as coatings and used in high speed laser printing and related printing processes. These conductive polymeric compositions and processes therefor provide improved stability and a broad range of conductivities, manufacturing and compositional latitude, and dielectric strength.
