Abstract
Abstract A yellow dye-donor element for thermal dye transfer comprising a plastic film support having thereon a yellow dye dispersed in a polymeric binder, the dye comprising an alkyl- or aryl-amino-pyridinyl- or pyrimidinyl-azo yellow dye which does not have any reactive pendant moiety capable of undergoing Michael-type addition. In a preferred embodiment of the invention, the dye has the formula: ##STR1## where R 1 and R 2 each independently represent 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; R 3 represents hydrogen or R 1 ; R 4 represents hydrogen or R 1 ; R 5 represents halogen; cyano; nitro; a substituted or unsubstituted alkyl or alkoxy group having from 1 to about 10 carbon atoms; a cycloalkyl group having from about 5 to about 7 carbon atoms; a substituted or unsubstituted aryl or aryloxy group having from about 6 to about 10 carbon atoms; COOR 1 ; CON(R 4 ) 2 ; NHCOR 1 ; NHSO 2 R 1 ; SO 2 R 1 ; or COR 1 ; X represents N or CR 6 ; R 6 represents hydrogen, halogen, cyano, CON(R 4 ) 2 , COR 1 , CO 2 R 1 or R 1 ; and n represents an integer from 0 to 5.
