  • Patent number: 6666596
    Abstract: Apparatus is disclosed for re-applying dye to a dye donor element of a dye transfer thermal printer. A reservoir contains a supply of dye that is thermally transferred from the reservoir to the dye donor element by diffusion of dye into the dye donor element. The reservoir has a diffusion controlled permeation membrane through which dye is delivered to the dye donor element, while inhibiting diffusion of a binder, whereby the dye diffuses between the reservoir and the dye donor element but the binder does not.
    Type: Grant

  • Patent number: 6440250
    Abstract: A process for laminating an ink jet print having the steps of: a) providing an ink jet print having a support having thereon an ink jet image; b) contacting the imaged surface of the ink jet print with a transfer laminating element to form a composite, the transfer laminating element having a flexible, polymeric support having thereon a protection layer of a water-dispersible, hydrophobic polyester resin having the following general formula: In-P-Am wherein I is an ionic group; n is an integer from 1-3; P is a polyester backbone; A is an aliphatic group having a straight or branched chain fatty acid or triglyceride thereof halving from about 6 to about 24 carbon atoms; and m is an integer from 3-8; c) applying heat and pressure to the composite to transfer the layer on top of the ink jet image; d) allowing the composite to cool; and e) peeling the flexible, polymeric support of the transfer laminating element from the composite to form the laminated ink jet print.

  • Patent number: 6280026
    Abstract: An ink jet printing process for improving the dye density and fixability of an ink jet image comprising: a) providing an ink jet recording element comprising a support having thereon an image-recording layer comprising a mixture of an anionic, water-dispersible polyester ionomer and a hydrophilic polymer; and b) applying droplets of a liquid ink on the image-recording layer in an image-wise manner, the ink comprising water, humectant and a water-soluble cationic or basic dye.

  • Patent number: 5789343
    Abstract: A thermal dye transfer assemblage comprising:(I) a dye-donor element comprising a support having thereon sequentially repeating dye layer patches of a dye dispersed in a polymeric binder, at least one of the dye patches containing a deprotonated cationic dye which is capable of being reprotonated to a cationic dye having a N--H group which is part of a conjugated system; and(II) a dye-receiving element comprising a support having thereon a polymeric dye image-receiving layer comprising a vinyl polymer having no or only slight acidity and a hydrated transition metal or metalloid salt of a strong acid, the dye-receiving element being in a superposed relationship with the dye-donor element so that the dye layer is in contact with the polymeric dye image-receiving layer.
