Abstract
A magenta dye-donor element for thermal dye transfer comprises a support having thereon a magenta dye dispersed in a polymeric binder, the magenta dye comprising a substituted 5-arylazoisothiazole. In a preferred embodiment, the magenta dye has the formula ##STR1## wherein R.sup.1 and R.sup.2 may each independently be hydrogen, alkyl, allyl, cycloalkyl or aryl; or R.sup.1 and R.sup.2 may be taken together to form a ring; or R.sup.1 or R.sup.2 may be part of a 5- or 6-membered heterocyclic ring; PA0 R.sup.3 may be hydrogen, alkyl, aryl, alkylthio or halogen; PA0 J may be alkyl, aryl or NHA, where A is an acyl or sulfonyl radical; and PA0 Q may be cyano, thiocyanato, alkylthio or alkoxycarbonyl.
