  • Method for fusing thermal dye transfer images
    Patent number: 5288689
    Abstract: A process of fusing a dye-receiving element for thermal dye transfer suitable for forming a slide for projection viewing, the dye-receiving element comprising a polymeric central dye image-receiving section and a polymeric frame section extending around the periphery of the central section, the dye image-receiving section containing a thermally-transferred dye image, the process comprising simultaneously subjecting the element to both conductive and convective heating.

  • Process for preparing dye-donor element for thermal dye transfer system processing
    Patent number: 5283226
    Abstract: This invention relates to a process of preparing a dye-donor element used in thermal dye-transfer processing comprising:a) coating a support with a dye layer comprising an image dye dispersed in a binder, the binder comprising a hydrophilic polymer coated from an aqueous solution containing a surfactant;b) washing the dye-donor element with water to remove residual surfactant in the dye layer; andc) drying the dye-donor element.
