<p>A yellow dye-donor element for thermal dye transfer comprises a support having thereon a dye dispersed in a polymeric binder, characterized in that the dye has the formula: <CHEM> wherein each R<1> independently represents hydrogen, a substituted or unsubstituted alkyl group having from 1 to 10 carbon atoms; a cycloalkyl group having from 5 to 7 carbon atoms or an aryl group having from 6 to 10 carbon atoms; R<2> represents a substituted or unsubstituted alkyl group having from 1 to 10 carbon atoms; a cycloalkyl group having from 5 to 7 carbon atoms or an aryl group having from 6 to 10 carbon atoms; R<3> and R<4> each independently represents R<1>, with the proviso that at least one of R<3> and R<4> is hydrogen; R<5> represents hydrogen; halogen; cyano; a substituted or unsubstituted alkyl, alkylthio, alkylsulfonyl, alkylsulfinyl, alkoxycarbonyl, carbamoyl or alkoxy group having from 1 to 10 carbon atoms; a substituted or unsubstituted arylthio, arylsulfonyl, arylsulfinyl, aryloxy or aryl group having from 6 to 10 carbon atoms; or a substituted or unsubstituted acylamido group having from 1 to 7 carbon atoms; and R<6> represents hydrogen; halogen; cyano; alkoxy; a substituted or unsubstituted alkyl group having from 1 to 10 carbon atoms; a cycloalkyl group having from 5 to 7 carbon atoms or an aryl group having from 6 to 10 carbon atoms.</p> |
