    摘要： Electrophotographic charge generating elements comprise a solid electrolyte layer having improved image discrimination and layer adhesion. The solid electrolyte layer includes a complex of a silsesquioxane and a charge carrier, and is adhered to an underlying photoconductor layer using a primer layer that includes specific addition polymers. This primer layer has a resistivity of at least 10.sup.10 ohms/square and contains substantially no free ACTIVE moieties as defined herein. Such groups, when present in the primer layer, appear to reduce image discrimination.

    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 mechanisms, and, is not substantially affected by humidity changes. The barrier layer includes a polyamide-co-imide having covalently bonded as repeat units in the polymer chain, aromatic tetracarbonylbisimide groups of the formula: wherein Ar1 and Ar2 respectively represent tetravalent or trivalent aromatic groups of 6 to about 20 carbon atoms, and X is O, C(CF3)2, S═O or SO2. The amount of aromatic tetracarbonylbisimide content in the polymer is selected such that the barrier layer can be coated onto the support as a relatively thick layer, which provides for enhanced performance as a photoconductor when used in an electrophotographic process.

An electrical barrier layer is disposed between the conductive support and the photoconductive layer.

    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： Pressure-sensitive, heat-fusible, encapsulated toner particles are provided which have very uniform size and physical characteristics. A method for making the particles is provided wherein a latex copolymer functions as a stabilizer controlling particle size of the core composition of the toner particles. The latex copolymer becomes the shell composition thereof. The particles are particularly useful in a process for transferring a toned image comprised of such particles from a photoconductor to a receiver.

    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.
