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 <IMAGE> wherein R1 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; R2 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; NHR6; NR6R7 or the atoms necessary to complete a 6-membered ring fused to the benzene ring; R3 and R4 each represents R1; or R3 and R4 can be joined together to form, along with the nitrogen to which they are attached, a 5- or 6-membered heterocyclic ring; or either or both of R3 and R4 can be joined to the carbon atom of the benzene ring at a position ortho to the position of attachment of the anilino nitrogen to form a 5- or 6-membered ring; R5 represents hydrogen; halogen; carbamoyl; alkoxycarbonyl; acyl; substituted or unsubstituted alkyl or alkoxy group group having from 1 to about 10 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 group; R6 and R7 each independently 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; or R6 and R7 may be joined together to form, along with the nitrogen to which they are attached, a 5- or 6-membered heterocyclic ring; and Z represents a hydrogen or the atoms necessary to complete a 5- or 6-membered ring.
