Stabilizers for dye-donor element used in thermal dye transfer

摘要

This invention relates to a dye-donor element for thermal dye transfer comprising a support having thereon a dye layer comprising a naphthol-p-phenylenediamine cyan dye in a polymeric binder, the dye layer also containing a stabilizer, the stabilizer comprising a compound containing a nitroxyl free radical and having a molecular weight of at least about 400 or a hydroxylamine moiety and having a molecular weight of at least about 330, the stabilizer being present in the amount of 5-10 mole % based on the weight of the dye.
