  • Publication number: 20040219296
    Abstract: A formulation and method of printing an ink or meltable ink layer having reactive dyes or mixtures of reactive dyes and disperse dyes as colorants. The ink or ink melt layer also includes an alkaline substance, a binder, and optionally, a heat-activated printing additive. Permanently bonded color images are provided by the reaction between the reactive dye and the final substrate, which may be any cellulosic, protein, or polyamide fiber material, or mixtures with polyester. Reaction occurs upon heat activation of the printed ink image.

  • Patent number: 6686314
    Abstract: A media for receiving a printed image during sublimation or heat activated liquid ink printing, and for transferring the image to a final substrate during subsequent heat transfer and activation. The media improves the quality of the finally transferred image and reduces the energy required to effect the transfer of the sublimation dyes. The media comprises multiple layers, including a feathering control layer containing a non-reactive, non-porous material; a dye screening layer, comprised of a porous material, which holds solid dye particles close to the surface of the media, while allowing other materials in the liquid ink to pass through; an absorbent liquid retaining layer; and a support layer. An optional permeation control layer allows liquids, such as aqueous or non-aqueous solutions, to pass through to subsequent layers during printing, while preventing dye vapor from penetrating beyond the dye screening layer during the final transfer step.

  • Patent number: 6673503
    Abstract: A reactive toner that is energy-activated is printed by means of an electrographic device such as a laser printer. The reactive toner is printed onto a substrate. Toner components that cross-link and bond the printed toner permanently onto the substrate, or another substrate through a transfer process, are activated by the application of energy to react after printing. Reaction of the energy-activated components may be inhibited with blocking or protecting agents. The image is permanently bonded onto the substrate when the protection provided by the protecting agents is removed by the application of energy to the printed toner. The toner may comprise energy-activated components, colorants, color enhancing polymeric materials, binder resins, internal and external additives such as waxes and charge control agents.

  • Patent number: 6631984
    Abstract: A method of printing using an ink or meltable ink layer which comprises dyes, pigments or other colorants. Bonding and/or crosslinking of the colorants is provided by the reaction between compounds selected from each of two chemical groups. The first group comprises compounds with functional groups capable of reacting with active hydrogen. The second group comprises compounds with functional groups containing active hydrogen, or compounds with functional groups containing active hydrogen after a conversion process. Either the first group or the second group is present in the ink, and an image is printed with the ink onto a substrate. The substrate comprises either the first or second group, as appropriate, to set up a later reaction with the ink. The reaction is delayed until the image is subsequently transferred to another substrate or is permanently fixed on the substrate, by the presence of protecting or blocking agents, which are removed by the application of heat or other energy.

  • Patent number: 6540345
    Abstract: A process for printing and transferring an image from a receiver sheet having a thermally transferable film to a final substrate. Only the imaged area of the film is transferred and permanently fixed to a final substrate, while the non-imaged area is processed to have little or no affinity for the final substrate, and is not bound to the final substrate.

  • Publication number: 20030000410
    Abstract: A color image is digitally printed onto an intermediate transfer medium. The image is subsequently transferred from the intermediate transfer medium to a final substrate, which may be a cellulosic textile, such as cotton. Bonding of the color images is provided by the reaction between compounds selected from each of two chemical groups contained in the intermediate transfer medium. The first groups comprises compounds with functional groups capable of reacting with active hydrogen, such as isocyanate or epoxy groups. The second group comprises compounds with functional groups containing active hydrogen, or compounds with functional groups containing active hydrogen after a conversion process. The functional groups of one or both reactive chemical groups may be protected either by blocking with internal or external blocking agents or by a physical barrier such as encapsulating agents.

  • Patent number: 6486903
    Abstract: A coated media is printed with ink. The area of the media which is not covered with ink is cured by exposure to radiation, and the printed image is transferred to a final substrate. The media is coated with a radiation curable coating. Upon exposure to electron beam or ultraviolet radiation, the coating in the exposed, non-imaged, area cures, and becomes permanently bonded to the base sheet. The ink layer of the imaged area effectively blocks, absorbs and/or reflects the radiation and does not allow polymerization under the imaged area. The image is transferred to a final substrate by placing the image in contact with the final substrate, followed by the application of energy. The image is permanently bonded to the final substrate. No overprint, or non-imaged area, that is visible or which may be felt by touching, is transferred to the final substrate.

  • Patent number: 6447629
    Abstract: A method of digitally printing reactive ink contained in a heat meltable ink layer comprising dyes or pigments or other colorants, using a thermal printer. The ink layer comprises compounds with functional groups capable of reacting with active hydrogen, and compounds with functional groups containing active hydrogen, or functional groups capable of conversion to active hydrogen containing groups. The reactive ink contains one or more blocking agents which prevent initiation of the reaction during thermal printing. An image is thermally printed onto a substrate, at a first temperature, so that the ink is not reacted during the process of printing on to the medium. The image is subsequently transferred or permanently fixed on the substrate by the application of heat and pressure, which removes the blocking agent and reacts the ink, bonding the colorant to the substrate.
