  • Patent number: 6986979
    Abstract: This invention relates to a composition comprising microcapsules suspended in an aqueous media, said microcapsules comprising a water immiscible material contained within an encapsulating wall of polymeric material, wherein the aqueous media contains a stabilizer comprising an anionic polymer mixture comprising a first sulfonated polystyrene polymer and a second sulfonated polystyrene polymer wherein the ratio of the weight average polymer molecular weight of the first polymer to the second polymer is greater than 2. It further relates to an imaging element comprising said microcapsules.

  • Patent number: 6825150
    Abstract: Disclosed is a thermal dye-transfer receiving element comprising a dye-image receiving layer on its top surface and, beneath the dye-image receiving layer, a microvoided layer containing a continuous phase polymer matrix having dispersed therein crosslinked organic microbeads, wherein the microbeads exhibit a glass transition temperature Tg that is below 80° C. Also disclosed is a method for making such thermal dye-transfer receiving elements.
