Thermal dye transfer assemblage with low TG polymeric receiver mixture |
摘要 |
A thermal dye transfer assemblage comprising: (I) 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 (II) 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 a) an organic polymeric or oligomeric acid which is capable of reprotonating said deprotonated cationic dye; b) a polymer having a Tg of less than about 19 DEG C. and having no or only slight acidity; and c) a monomeric, multifunctional organic acid with at least two acid groups attached.
