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, said dye being: I) an electrically neutral, deprotonated, delocalized cationic dye precursor; II) a pendant basic dye of the formula D-(L-E)m wherein D represents the residue of a dye, L represents a linking group, E represents a moiety with basic properties and m is an integer of 1-3; or III) a cationic dye precursor having the following structure: 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 dye image-receiving layer, the dye image-receiving layer comprising a mixture of i) a polymer having a Tg of less than about 19 DEG C. and having no or only slight acidity; and ii) a polyester which has been polymerized in the presence of an aluminum salt and which contains an aluminum ion.
