  • Publication number: 20030050191
    Abstract: An imaging medium comprises a color change layer containing a leuco dye. An acidic developing layer comprising a polyhydroxystyrene reacts with said color change layer to produce a color upon the application of heat. The polyhydroxystyrene may be used alone or in combination with traditional leuco dye developers.

  • Publication number: 20030032557
    Abstract: Disclosed herein is an imaging medium comprising a substrate carrying a color-change layer which develops color upon heating. The addition of a novel block copolymer surfactant containing ethylene oxide (EO) and propylene oxide (PO) into the leuco dye dispersion prevents color pre-formation during the dispersion preparation stage, and in the final coating fluid in the presence of developers and acids. The pluronic may complex the acid developer as well as the final image dye.
