Abstract:
An orange dye-donor element for thermal dye transfer comprising a support having thereon a dye layer comprising a mixture of a pink dye and a first and second yellow dye dispersed in a polymeric binder, said pink dye having the formula A: ##STR14## wherein: R.sup.1, R.sup.2 and R.sup.3 each independently represents a substituted or unsubstituted alkyl group having from 1 to about 10 carbon atoms; a substituted or unsubstituted cycloalkyl group having from about 5 to about 7 carbon atoms; a substituted or unsubstituted allyl group; a substituted or unsubstituted aryl group of from about 6 to about 10 carbon atoms; or a substituted or unsubstituted hetaryl group of from about 5 to about 10 atoms;X represents C(CH.sub.3).sub.2, S, O or NR.sub.1 ; andY represents the atoms necessary to complete a 5- or 6-membered ring which may be fused to another ring system;said first yellow dye having the formula B having the structure: ##STR15## wherein: R.sup.5 represents the same groups as R.sup.1, R.sup.2 and R.sup.3 above;R.sup.4 represents any of the groups for R.sup.5 or represents the atoms which when taken together with Z.sup.1 forms a 5- or 6-membered ring;Z.sup.1 represents hydrogen; a substituted or unsubstituted alkyl group having from 1 to about 10 carbon atoms; alkoxy; halogen; or represents the atoms which when taken together with R.sup.4 forms a 5- or 6-membered ring;each W.sup.1 independently represents a substituted or unsubstituted alkyl group having from 1 to about 10 carbon atoms; alkoxy having from 1 to about 10 carbon atoms; halogen; or two adjacent W.sup.1 's together represent the atoms necessary to complete a 5- or 6-membered ring, thus forming a fused ring system; andm represents an integer from 0 to 2;said second yellow dye having the formula F or G, said formula F having the structure: ##STR16## wherein: R.sup.12 represents methyl or 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;R.sup.13 represents a substituted or unsubstituted alkyl group of from 1 to about 10 carbon atom; a cycloalkyl group of from about 5 to about 7 carbon atoms; or a substituted or unsubstituted aryl group of from about 6 to about 10 carbon atoms;R.sup.14 and R.sup.15 each independently represents hydrogen or a substituted or unsubstituted alkyl or alkoxy group having from 1 to about 4 carbon atoms; andsaid formula G having the structure: ##STR17## wherein: R.sup.17, R.sup.18 and R.sup.19 each independently represents the same groups as R.sup.1, R.sup.2 and R.sup.3 above;R.sup.16 represents any of the groups for R.sup.17, R.sup.18 and R.sup.19 or represents the atoms which when taken together with Z forms a 5- or 6-membered ring;Z represents hydrogen; a substituted or unsubstituted alkyl group having from 1 to about 10 carbon atoms; alkoxy; halogen; or represents the atoms which when taken together with R.sup.16 forms a 5- or 6-membered ring;each W independently represents a substituted or unsubstituted alkyl group having from 1 to about 10 carbon atoms; alkoxy having from 1 to about 10 carbon atoms; halogen; or two adjacent W's together represent the atoms necessary to complete a 5- or 6-membered ring, thus forming a fused ring system; andn represents an integer from 0 to 2.
