摘要： Controllably conductive polymer compositions may be used in electrophotographic imaging developing systems, such as scavengeless or hybrid scavengeless systems or liquid image development systems. The conductive polymer compositions includes a charge-transporting material (particularly a charge-transporting, thiophene-containing polymer or an inert elastomeric polymer, such as a butadiene- or isoprene-based copolymer or an aromatic polyether-based polyurethane elastomer, that additionally comprises charge transport molecules) and a dopant capable of accepting electrons from the charge-transporting material. The invention also relates to an electrophotographic printing machine, a developing apparatus, and a coated transport member, an intermediate transfer belt, and a hybrid compliant photoreceptor comprising a composition of the invention.

摘要： An unsymmetrical squaraine composition, process for synthesizing the unsymmetrical squaraine composition, devices containing the unsymmetrical squaraine composition, and methods of using the devices. The process for synthesizing the unsymmetrical squaraine composition comprises forming a mixture comprising squaric acid, a long chain primary alcohol, a first tertiary amine, and a second tertiary aromatic amine different from the first tertiary aromatic amine, and heating the mixture in vacuo below the boiling points of the primary alcohol, the first tertiary amine and the second tertiary aromatic amine to form an unsymmetrical squaraine composition. The novel unsymmetrical squaraine composition synthesized by this process may be used in electrostatographic imaging members comprising a supporting substrate and a photoconductive layer comprising the novel unsymmetrical squaraine composition. These electrostatographic imaging members may be utilized in an electrostatographic imaging processes.
