Assemblage for thermal dye transfer

摘要

A thermal dye transfer assemblage comprising: (I) a dye-donor element comprising a support having thereon sequentially repeating dye layer patches of a dye dispersed in a polymeric binder, at least one of the dye patches containing a pendant basic-substituted dye having the formula: A-(L-B)m wherein: A represents a thermally transferable dye residue, L represents a divalent linking group, B represents a basic substituent, and m represents an integer of from 1 to 3; 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 containing a hydrated transition metal or metalloid salt of a strong acid.
