    摘要： This invention is generally directed to a process for preparing chalcogenide alloys of high purity which comprises providing the corresponding pure esters of the elements desired in an organic medium, and an organic salt followed by simultaneously coreducing the esters by an electrochemical reduction in an electrolytic apparatus. More specifically, in one embodiment, selenium arsenic, alloys of high purity are prepared by subjecting the corresponding pure esters to a simultaneous electrochemical reduction reaction in an electrochemical apparatus containing an anode, a cathode, an electrolytic solution comprised of the pure esters of selenium and arsenic, contained in a solution of an organic solvent, and an organic salt wherein the pure esters lose electrons resulting in the desired metallic alloys.

    摘要： A process comprising incorporating into an ink jet printing apparatus a developing composition; an oxidizing composition a coloring composition; and a fixing composition; ejecting droplets of the developing composition onto the substrate; ejecting droplets of the oxidizing composition onto the substrate; ejecting droplets of the coloring composition onto the substrate; and ejecting droplets of the fixing composition onto the substrate; wherein the process results in at least some portions of the substrate bearing images comprising all four compositions, the portions forming a printed image. Specific embodiments are directed to the realization of continuous tone and gray scale in image by control of the time at which color forming reactions are quenched by controlling the lime period between deposition of the color forming liquids and deposition of the fixing liquid; or control of the extent of color forming reactions by limitation of the quantity of one of the color forming liquids.

    摘要： A process comprising (a) incorporating into an ink jet printing apparatus (1) a developing composition comprising a liquid vehicle and a color developer; (2) an oxidizing composition comprising a liquid vehicle and an oxidizing agent; (3) a coloring composition comprising a liquid vehicle and a dye coupler; and (4) a fixing composition comprising a liquid vehicle and a fixative; (b) causing droplets of the developing composition to be ejected in an imagewise pattern onto the substrate; (c) causing droplets of the oxidizing composition to be ejected in an imagewise pattern onto the substrate; (d) causing droplets of the coloring composition to be ejected in an imagewise pattern onto the substrate; and (e) causing droplets of the fixing composition to be ejected in an imagewise pattern onto the substrate; wherein the process results in at least some portions of the substrate bearing images comprising all four of the developing composition, the oxidizing composition, the coloring composition, and the fixing composition, said portions forming a printed image. Specific embodiments of the present invention are directed to the realization of continuous tone and gray scale in images by (1) control of the time at which color forming reactions are quenched by controlling the time period between deposition of the color forming liquids and deposition of the fixing liquid; (2) control of the extent of color forming reactions by limitation of the quantity of one of the color forming liquids; or (3) control of pixel size by drop placement control over the overlap areas of drops of color forming liquids.
