Thermal dye transfer system with receiver containing reactive carbonyl group

摘要

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 substituted with a reactive primary or secondary aliphatic amino group, and (b) a dye-receiving element comprising a support having thereon a 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 polymer containing a plurality of functional groups: R2-CO-X-R3 wherein: R2 represents alkyl, aryl, alkoxy or aryloxy; X represents oxygen or sulfur; and R3 represents aryl or hetaryl; with the proviso that R2 or R2 and R3 are directly attached to the polymer chain.
