摘要： This invention is directed to a layered organic photoresponsive device, and a method of highlight color imaging, the device being comprised of (1) a supporting substrate, (2) a layer of material capable of injecting holes into a layer on its surface, this layer being comprised of a material selected from the group consisting of carbon dispersed in a polymer, and graphite dispersed in a polymer, (3) a hole transport layer in operative contact with the layer of hole injecting material, which transport layer comprises a combination of a highly insulating organic resin having dispersed therein small molecules of an electrically active material, the combination of which is substantially nonabsorbing to visible light but allows injection of photogenerated holes from a photogenerating layer in contact with the hole transport layer, and electrically induced holes from the layer of injecting material, (4) a red sensitive charge carrier photogenerating layer sensitive to wavelengths ranging from about the visible range to about 620 millimicrons, said layer being transparent to light of wavelengths of greater than 620 millimicrons, (5) a top layer of a photoconductive material sensitive only to relatively short wavelengths ranging from about the visible range to about 620 millimicrons, said layer being transparent to light of wavelengths of greater than 620 millimicrons. Highlight imaging is accomplished by subjecting the above device to negative charges, followed by subjecting the device to positive charges, imagewise exposing the member, and developing with a colored developer composition comprised of positively charged toner components and negatively charged toner components, and carrier particles.

摘要： Process for preparation of a solid phase dispersion of photoconductive materials in an insulating binder matrix from a film forming insulating polymeric resin and an organo-selenium compound capable of undergoing selective decomposition in response to an appropriate stimulus; whereby, elemental selenium is extruded from said organo-selenium compound and deposited in the binder matrix. Because this extrusion/deposition of elemental selenium can be performed selectively, it is possible to prepare binder films having photoconductive image patterns which are suitable for use in range extended and conventional xerography.

摘要： Disclosed is an adhesive generating layer for use in an overcoated photoreceptor system, this layer containing a generating pigment dispersed in a copolymer of a siloxane and a dihydroxy compound of the formula: ##STR1## wherein R and R' are independently selected from the group consisting of alkyl, substituted alkyl, alkenes, substituted alkenes, aryl and substituted aryl; Y is a dihydroxy radical; and n is a number of sufficient value that the average molecular weight of the resulting silicone copolymer is between about 2,000 and 250,000. Examples of copolymers include those wherein R and R' are alkyl groups such as methyl and Y is a biphenol such as 2,2-bis-(4-hydroxy phenyl)-propane, one preferred material being a methyl octyl siloxane 2,2-bis-(4-hydroxy phenyl)-propane copolymer. Examples of pigments that are dispersed in the generating layer include metal free phthalocyanines, such as X phthalocyanine, alpha phthalocyanine, beta phthalocyanine, metal phthalocyanines such as vanadyl phthalocyanine, selenium, selenium containing compounds such as selenium alloys including selenium arsenic, selenium bismith, and other types of selenium compounds such as trigonal selenium. This adhesive generating layer is useful in an overcoated photoreceptor containing for example an electrically conductive substrate, overcoated with a layer of material capable of injecting holes into a layer on its surface, a hole transport layer in operative contact with the layer of hole injecting material, overcoated by a layer of the charge generating adhesive material on and in operative contact with the charge transport layer and a layer of an insulating organic resin overlaying the charge generating layer.

摘要： Method for in situ preparation of photoconductive composite having an electronically active hole transport layer, an electronically active electron transport layer and a layer of charge transfer complex sandwiched therebetween. According to this method, a film containing either an electron donor or an electron acceptor is initially formed directly on a supportive (preferably conductive) substrate. After this film has been allowed to set, a second film is solvent coated on the previously formed film. The solvent used in preparation of the second film causes softening of the previously formed layer which permits interaction of an electron acceptor or an electronic donor in the casting solvent with an electron acceptor or an electron donor of the previously formed layer, thereby forming a charge transfer complex at the interface of these two films. Only a portion of the donor and acceptor interact along this common boundary during the formation of the photoconductive composite. The balance of the noncomplexed donor and acceptor remain unperturbed in their respective layers, thus providing rapid and efficient transport of both species of charge carriers from within the bulk of the film upon photoactivation of the charge transfer complex.
