Abstract
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: ##STR1## 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; PA1 R.sup.1 is an alkylene or substituted alkylene group; PA1 X is --OJO--, --OJ--, --JO--, --OJNR.sup.3 --, --NR.sup.3 J--, --NR.sup.3 JNR.sup.3, --JNR.sup.3 -- or --NR.sup.3 JO--; PA1 J is CO or SO.sub.2 ; PA1 R.sup.3 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 R.sup.2 forms a 5- or 6-membered ring; PA1 R.sup.2 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 …
