Abstract: A data sheet is composed of an upper part and a lower part. The upper part is used as a user interface including a reduced image of contents of a document. The lower part is an interface for a reading device such as a copy machine, including a code obtained by encoding the document. By use of the data sheet, the user can easily distribute or carry an electronic document data with the user. In addition, the user can recognize contents of the electronic document data by looking at the reduced image printed on the data sheet.

Abstract: An electrophotographic imaging process having a double charging sequence and a photoreceptor utilized therein are provided, wherein the photoreceptor comprises a substrate, a photosensitive layer comprising a squaric acid methine dye, and an insulating layer. The photosensitive layer may also comprise a squaric acid methine dye and a charge transport material.

Abstract: The present invention provides a photosensitive material for use in electrophotography which comprises a conductive support having a photoconductive layer coated with a protective layer, the material being superior in light-decay property, mechanical strength and image formability, wherein said protective layer is composed of either (1) a member selected from the group of resins consisting of polyvinyl butyral, polyvinyl acetate, acryl or derivative resins thereof, copolymers of styrene and maleic anhydride or alkyl esters thereof, copolymers of vinyl acetate or derivatives thereof and vinyl pyrrolidone, copolymers of butyl vinyl ether and maleic anhydride or alkyl monoesters thereof and shellac, or of (2) a resin and silane-coupling agent.

Abstract: Photoconductive, film forming nitropyrene-formaldehyde resins characterized by a repeating structural unit of the formula: ##SPC1##And process for preparation, the photoconductive films themselves, and such films on an electrically conductive support.

Abstract: There are provided sensitizers for electrophotographic light-sensitive materials including organic photoconductors and electrophotographic light-sensitive materials containing same. The sensitizers are reaction products comprising benzopyrylium salt and benzopyran.
