YELLOW DYE MIXTURE FOR THERMAL COLOR PROOFING Abstract of the Disclosure A yellow dye-donor element for thermal dye transfer comprises a support having thereon a dye layer comprising a mixture of yellow dyes dispersed in a polymeric binder, at least one of the yellow dyes having the formula: I Image wherein: each R1 independently represents 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 allyl group; an aryl group of from about 6 to about 10 carbon atoms; a hetaryl group of from 5 to 10 atoms; acyl; arylsulfonyl; aminocarbonyl; aminosulfonyl; fluorosulfonyl; halogen; nitro; alkylthio; or arylthio; or any two adjacent R1's together represent the atoms necessary to form a 5- or 6-membered fused ring; n represents an integer from 0-4; R2 represents hydrogen; a substituted or unsubstituted alkyl, cycloalkyl, allyl, aryl or hetaryl group as described above for R1; cyano; acyl; alkylsulfonyl; arylsulfonyl; or alkoxycarbonyl; Z represents cyano; alkoxycarbonyl; acyl; nitro; arylsulfonyl or alkylsulfonyl; Y represents hydrogen; a substituted or unsubstituted alkyl, cycloalkyl, allyl, aryl or hetaryl group as described above for R1; amino; alkylamino; arylamino; acylamino; or sulfonylamino; and at least one of the other of the dyes having the formula: Image II wherein: R6 represents 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 allyl group; or an aryl group having from about 6 to about 10 carbon atoms; R7 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; NHR8; NR8R9 or the atoms necessary to complete a 6-membered ring fused to the benzene ring; R3 and R4 each represents any of the groups for R6, 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, thus forming a polycyclic system; R5 represents hydrogen; 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 allyl group; carbamoyl; or alkoxycarbonyl; R8 and R9 each independently represents any of the groups fox R6; or R8 and R9 may be joined together to form, along with the nitrogen to which they are attached, a 5-or 6-membered heterocyclic ring; m is a positive integer from 1 to 4; and G represents a substituted or unsubstituted alkyl or alkoxy group of from 1 to about 10 carbon atoms; halogen; aryloxy; or any two adjacent G's together represent the atoms necessary to complete a 5- or 6- membered ring, thus forming a fused ring system.
