Abstract
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: wherein R¹ and R² may each independently be hydrogen, alkyl, allyl, cycloalkyl or aryl; or R¹ and R² may be taken together to form a ring; or R¹ or R² may be part of a 5- or 6-membered heterocyclic ring; R³ may be hydrogen, alkyl, aryl, alkylthio or halogen; J may be alkyl, aryl or NHA, where A is an acyl or sulfonyl radical; and Q may be cyano, thiocyanato, alkylthio or alkoxycarbonyl.
