A yellow dye-donor element for thermal dye transfer comprises a support having thereon a yellow dye dispersed in a polymeric binder, the yellow dye having the formula: <IMAGE> wherein R is a substituted or unsubstituted alkyl group of from 1 to about 10 carbon atoms; a cycloalkyl group of from about 5 to about 7 carbon atoms; or represents the atoms which when taken together with Z forms a 5- or 6-membered ring; R1 is an alkylene or substituted alkylene group; X is -OJO-, -OJ+13, -JO-, -OJNR3-, -NR3J-, -NR3JNR3, -JNR3- or -NR3JO-; J is CO or SO2; R3 is hydrogen; a substituted or unsubstituted alkyl group of from 1 to about 10 carbon atoms; a substituted or unsubstituted aryl group of from about 6 to about 10 carbon atoms; or represents the atoms which when taken together with R2 forms a 5- or 6-membered ring; R2 is a substituted or unsubstituted alkyl group of from 1 to about 10 carbon atoms; a cycloalkyl group of from about 5 to about 7 carbon atoms; a substituted or unsubstituted aryl group of from about 6 to about 10 carbon atoms; or represents the atoms which when taken together with R3 forms a 5- or 6-membered ring; Z is hydrogen or represents the atoms which when taken together with R forms a 5- or 6-membered ring; Y is a substituted or unsubstituted alkyl or alkoxy group of from 1 to about 6 carbon atoms or halogen; and n is a positive integer from 1 to 4.
