Abstract
A dye-donor element for thermal dye transfer comprises a support having thereon a dye dispersed in a polymeric binder, the dye having the formula: ##STR1## wherein R.sup.1 represents a substituted or unsubstituted alkyl group having from 1 to about 10 carbon atoms; a cycloalkyl group having from about 5 to about 7 carbon atoms or an aryl group having from about 6 to about 10 carbon atoms; PA1 R.sup.2 represents a substituted or unsubstituted alkoxy group having from 1 to about 10 carbon atoms; a substituted or unsubstituted aryloxy group having from about 6 to about 10 carbon atoms; NHR.sup.6 ; NR.sup.6 R.sup.7 or the atoms necessary to complete a 6-membered ring fused to the benzene ring; PA1 R.sup.3 and R.sup.4 each represents R.sup.1 ; or R.sup.3 and R.sup.4 can be joined together to form, along with the nitrogen to which they are attached, a 5- or 6-membered heterocyclic ring; PA1 R.sup.5 represents hydrogen; halogen; carbamoyl; alkoxycarbonyl; acyl; a substituted or unsubstituted alkyl or alkoxy group having from 1 to about carbon atoms; a cycloalkyl group having from about 5 to about 7 carbon atoms; an aryl group having from about 6 to about 10 carbon atoms; or a dialkylamino…
