摘要： Disclosed are photoconductive elements including a conductive support, e.g., an electrically conductive film, drum, or belt, on which a negatively chargeable photoconductive layer is disposed. An electrical barrier layer is disposed between the conductive support and the photoconductive layer. The barrier layer provides a high energy barrier to the injection of positive charges, but transports electrons under an applied electric field. In embodiments, the barrier layer can transport charge by electronic, or both electronic and ionic mechanisms, and, is not substantially affected by humidity changes. The barrier layer includes a polyester-co-imides, polyesterionomer-co-imides, or polyamide-co-imides having covalently bonded as repeat units in the polymer chain, aromatic tetracarbonylbisimide groups of the formula:

摘要： Disclosed are polymers which include tertiary aryl amine moieties that can function as hole transport agents and which also have reactive silane groups thereon capable of being condensed to a silsesquioxane composition, as well as the silsesquioxane compositions prepared therefrom. The silsesquioxanes can be coated onto substrates to form abrasion-resistant layers having hole transport properties useful in devices that require charge transport properties, such as light-emitting diodes and organic electrophotographic elements such as photoreceptors or photoconductors. Also disclosed are electrophotographic elements which comprise an electrically conducting layer, a charge generating layer overlying the electrically conducting layer, and a charge transport layer overlying the electrically conducting layer. The charge transport layer, which can be an overcoat overlying the charge generating layer, comprises the condensed reaction product of the disclosed polymers.

摘要： In a photoconductive element comprising a conductive support, e.g., an electrically conductive film, drum or belt on which a negatively chargeable photoconductive layer is formed, an electrical barrier layer is formed between the support and the photoconductive layer. The barrier layer provides a high energy barrier to the injection of positive charges but transports electrons under an applied electric field. The barrier layer of the invention transports charge by electronic rather than ionic mechanisms and, therefore, is not substantially affected by humidity changes. The barrier layer comprises a polyester-co-imide, polyesterionomer-co-imide or polyamide-co-imide having covalently bonded as repeating units in the polymer chain, aromatic tetracarboxylbisimide groups of the formula:

摘要： In a process for forming an amorphous pigment mixture consisting essentially of TiOPc and TiOFPc and containing more than about 75 weight percent of TiOPc, a mixture of crude crystalline TiOPc and TiOFPc pigments in a weight ratio of at least 75:25 TiOPc: TiOFPc is combined with at least about 5 wt.%, based on the total weight of TiOPc and TiOFPc, of an organic milling aid. The mixture is treated under conditions effective to form a substantially amorphous pigment mixture of TiOPc and TiOFPc. The organic milling aid can be separated from the substantially amorphous pigment mixture, which can be converted to a nanoparticulate cocrystalline TiOPc/TiOFPc composition.
