Thermal dye transfer assemblage with low Tg polymeric receiver mixture

U.S. Patent Number: 5733846

Abstract: A thermal dye transfer assemblage comprising: (a) a dye-donor element comprising a support having thereon a dye layer comprising a dye dispersed in a polymeric binder, the dye being 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 (b) a dye-receiving element comprising a support having thereon a polymeric dye image-receiving layer, 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, the polymeric dye image-receiving layer comprising a mixture of i) a polymer having a Tg of less than about 19.degree. C. and having no or only slight acidity; and ii) a polymeric acid with a saturated hydrocarbon backbone capable of reprotonating the deprotonated cationic dye.
