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： Process for preparation of transparencies from a solid phase dispersion of photoconductive particles in an insulating binder matrix. In this process, a dispersion is initially formed from an insulating polymer resin and an organoselenium compound capable of undergoing selective decomposition in response to an appropriate stimulus, whereby elemental selenium is extruded from said organoselenium compound and deposited within the polymeric resin. As a result of this deposition of elemental selenium within the insulating layer, the layer is rendered photoresponsive and can be used in conventional electrophotographic processes. Subsequent to the development and fusion of a developer image on this imaging member, the extrusion/deposition reaction can be reversed and the selenium deposit erased thus leaving a toner image fused to a substantially transparent polymeric film.

Irradiation of these films with activating radiation results in dark images in light struck areas and colorless background. The microimaging film is a negative working system with add-on reimaging capability. The images are stable to projection in conventional slide projection systems.
