摘要： An electrophotographic coating composition comprising finely-divided photoconductive perylene pigment dispersed in a solvent solution of polymeric binder is prepared by the steps of (1) milling a perylene pigment with milling media comprising inorganic salt and non-conducting particles under shear conditions in the substantial absence of the solvent to provide pigment having a particle size up to 0.2 micrometer, (2) continuing the milling at higher shear at a temperature up to about 50.degree. C., to achieve a perceptible color change of the pigment particles, (3) rapidly reducing the temperature of the milled pigment by at least 10.degree. C., (4) separating the milled pigment from the media and (5) mixing the milled pigment with the solvent solution of polymeric binder to form the coating composition. A very high degree of dispersion of photoconductive perylene pigment in solvent solution of polymeric binder is achieved by this method.

摘要： Derivatives of diiminoquinones are useful as electron transport agents in electrophotography. The diiminoquinone derivatives are inexpensive materials, requiring only two steps to synthesize, have excellent solubility and compatibility with most binders due to the presence of long alkyl chains, and evidence high electron mobility.

摘要： In organic photoconductors (OPC's) for electrophotography, a barrier layer is placed on top of the OPC. The barrier may have 2 layers--1, an electron withdrawing layer on top of the OPC; and,--2, an electron donating layer on top of the electron withdrawing layer. The barrier layer comprises: 1. a crosslinked polymer binder; 2. a charge injection prohibiter molecule, and optionally; 3. an electron withdrawing molecule. This formulation has resulted in a long-life OPC with more than 50,000 good cycles at high severity test conditions. The OPC had not only long life during continuous use, but also long shelf life and long on-again/off-again operation life.

摘要： A composite organic photoconductor for electrophotography is described. The composite photoconductor includes a conductive support, a charge generation layer and a particulate charge transport layer disposed between the conductive support and the charge generation layer. The charge transport layer is formed from a first colorant composition comprising a particulate pigment embedded in a polymeric matrix. The charge generation layer is formed from a second colorant composition which comprises either a pigment or a dye. The charge transport layer has an infrared absorption maximum of about 740 nm, and the charge generation layer has an infrared absorption maximum greater than about 770 nm. The composite organic photoconductor exhibits both good electrophotographic response and superior thermal stability over a range of operating conditions, and is thus useful in a number of electrophotographic processes such as those employing charging, exposing and developing operations to form images.

摘要： High efficiency transfer of liquid toner image from an photoconductor onto an image receiver (e.g., plain paper, transparency film, and the like) using a simple and direct, one-step process, is provided. The transfer is effected using a hard (non-conformable) substrate, at least one conformable intermediate mat, the photoconductor having a release surface comprising a siloxane, the image receiver, a roller, and a source of heat and pressure. One conformable layer may be employed, resulting in two possibilities. In the first possibility, the roller comprises the source of heat and pressure and the conformable layer supports the photoconductor layer. A non-conformable layer supports the conformable layer. In the second possibility, the source of heat and pressure is on that surface of the photoconductor opposite that on which the toner image is carried and the conformable layer is positioned between the roller and the image receiver. In yet another embodiment, two conformable layers are employed, with a first conformable layer supporting the photoconductor layer and a second conformable layer positioned between the roller and the image receiver, with a non-conformable layer supporting the first conformable layer. The roller provides the source of heat and pressure.
