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： A xeroprinting master is formed by depositing a corona charge injection modifying material on a master substrate which includes a charge transport layer. The material can block the injection of charge that would otherwise inject into the charge transport layer or it can inject charge that would otherwise remain on the surface of the master. Preferably, the deposit is made by a conventional printer such as an ink jet, impact or thermal printer and the resulting deposit is not fused before use in xeroprinting.

摘要： An improved interlayer is provided for use in a photoconductor element between an electrically conductive layer and a charge generation layer of the type where a dye is aggregated in a matrix polymer. The interlayer is a mixture of at least one polyester and at least one polycarbonate. The interlayer provides excellent adhesion between the conductive layer and the charge generation layer and dampens any stress to which the photoconductive element is subjected. Minimal effect on photosensitivity is achieved by optimizing interlayer thickness.
