Abstract (en)

[origin: WO9956180A1] Methods of making a charge generation layer comprise premixing a charge generation compound, a charge transport compound and solvent to form a premix essentially free of polymeric binder, mixing the premix with at least one polymeric binder to form a dispersion, and coating the dispersion on a substrate. Photoconductors comprising a substrate, a charge transport layer and a charge generation layer formed by such a method exhibit improved electrical sensitivity.
