    摘要： A platen cover for an imaging device such as a copier or scanner includes a substrate and at least of portion of the surface of the substrate is coated with a fluorescent coating. Preferably, the substrate has a dark or black color. The dark color of the substrate substantially reduces or eliminates show through of an image on the backside of an original document when the platen cover is not exposed to a light source for imaging. At the same time, when holes or uneven borders are present in the original document, the fluorescent coating fluoresces upon exposure to the light source at these regions of the original document, making these portions appear white in the replicated image and thereby substantially reducing or eliminating the unsightly appearance of these portions as black portions in the replicated image.

    摘要： Novel emissive materials suitable for organic light emitting devices are disclosed having a structure (L2M)n—X wherein L is a 2-alkyl-8-quinolinolate or 2-phenyl-8-quinolinolate ligand, M is a trivalent metal atom, n is an integer between 1 and 12. When n equals 1, X comprises a monovalent arylate emitter that contains at least one triarylamine group or a light emitting group with emission peak wavelength in the range of 500-750 nm. When n equals 2, X comprises a divalent arylate emitter that contains at least one triarylamine group or a light emitting group with emission peak wavelength in the range of 500-750 nm. When 3≦n≦12, X is an n-valent arylate group.

    摘要： A flexible electrostatographic imaging belt having two parallel sides and a non imaging seam region extending substantially from one of the sides to the other side, the non-imaging seam region having a leading edge, a trailing edge and a seam within the non imaging seam region, the leading and trailing edges being perpendicular to the two parallel sides of the imaging belt, the belt comprising a substrate layer, a reflective electrically conductive layer, at least one imaging layer, an imaging region extending around the belt from adjacent the leading edge of the seam region to adjacent the trailing edge, the imaging region adapted to reflect monochromatic infrared radiation and a permanent localized solid attribute at a predetermined location in the non imaging seam region, the attribute adapted to reduce by at least about 50 percent direct reflection by the seam itself of a beam of monochromatic infrared radiation originally directed at the attribute. This belt is used in imaging apparatus and imaging processes.
