Abstract:
A process for making a green color proof of a printed color image comprising:a) generating a set of electrical signals which is representative of the shape and color scale of an original green image;b) contacting a green dye-donor element comprising a support having thereon a dye layer and an infrared-absorbing material with an intermediate dye-receiving element comprising a support having thereon a polymeric, dye image-receiving layer;c) using the signals to imagewise-heat said dye-donor element, thereby transferring a dye image to said intermediate dye-receiving element; andd) retransferring said dye image to a final dye image-receiving element which has the same substrate as said printed color image;wherein said green dye-donor element comprises a support having thereon a dye layer consisting essentially of a mixture of a yellow dye and a cyan dye dispersed in a polymeric binder, said yellow dye having the formula A: ##STR14## wherein: R.sup.1 is 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; or a substituted or unsubstituted hetaryl group having from about 5 to about 10 atoms;R.sup.2 is any of the groups for R.sup.1 or represents the atoms which when taken together with Z forms a 5- or 6-membered ring;Z is hydrogen; any of the groups listed above for R.sup.1, alkoxy; halogen; aryloxy; or represents the atoms which when taken together with R.sup.2 forms a 5- or 6-membered ring;each Y independently represents any of the groups for R.sup.1, alkoxy having from 1 to about 10 carbon atoms; halogen; or two adjacent Y'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;said cyan dye has either the following formula B or C wherein said formula B has the structure: ##STR15## wherein: R.sup.4 and R.sup.5 each independently represents hydrogen; a substituted or unsubstituted alkyl group having from 1 to about 6 carbon atoms, a substituted or unsubstituted cycloalkyl group having from about 5 to about 7 carbon atoms; or a substituted or unsubstituted allyl group;R.sup.4 and R.sup.5 can be joined together to form, along with the nitrogen to which they are attached, a 5- to 7-membered heterocyclic ring;each R.sup.3 independently represents substituted or unsubstituted alkyl, cycloalkyl or allyl as described above for R.sup.4 and R.sup.5, alkoxy, aryloxy, halogen, thiocyano, acylamido, ureido, alkylsulfonamido, arylsulfonamido, alkylthio, arylthio or trifluoromethyl;or any two of R.sup.3 may be combined together to form a 5- or 6-membered carbocyclic or heterocyclic ring;or one or two of R.sup.3 may be combined with either or both of R.sup.4 and R.sup.5 to complete a 5- to 7-membered ring;m is an integer from 0 to 3;X represents hydrogen, halogen or may be combined together with W to represent the atoms necessary to complete a 6-membered aromatic ring, thus forming a fused bicyclic quinoneimine; with the proviso that when X is hydrogen, then J represents NHCOR.sub.F, where R.sub.F represents a perfluorinated alkyl or aryl group; and with the further proviso that when X is halogen, then J represents NHCOR.sup.1, NHCO.sub.2 R.sup.1, NHCONHR.sup.1 or NHSO.sub.2 R.sup.1 ; and with the fuirther proviso that when X is combined with W, then J represents CONHR.sup.1, SO.sub.2 NHR.sup.1, CN, SO.sub.2 R.sup.1 or SW is hydrogen, R.sup.1 as define above, acylamino or may be combined with X as described above; andJ represents hydrogen or the groups shown above in the provisos; andsaid formula C has the structure: ##STR16## wherein: R.sup.6 is a substituted or unsubstituted alkyl group having from 1 to about 6 carbon atoms; a substituted or unsubstituted allyl group having from 3 to about 6 carbon atoms; a substituted or unsubstituted acyl group having from 2 to about 9 carbon atoms; a substituted or unsubstituted aroyl group having from about 7 to about 18 carbon atoms; or a substituted or unsubstituted heteroaroyl group having from about 5 to about 10 carbon atoms;R.sup.7 and R.sup.8 each independently represents a substituted or unsubstituted alkyl group having from 1 to about 8 carbon atoms; a cycloalkyl group having from about 5 to about 7 carbon atoms; or a substituted or unsubstituted alkenyl group having from about 2 to about 8 carbon atoms;R.sup.7 and R.sup.8 may represent the elements which may be taken together to form a 5- or 6-membered heterocyclic ring;each V independently represents hydrogen; a substituted or unsubstituted alkyl group having from 1 to about 8 carbon atoms; OR.sup.1 wherein R.sup.1 is as defined above; halogen; or two adjacent V's may represent the atoms which may be taken together to form a fused carbocyclic aromatic ring;the position of V ortho to the nitrogen may also be combined with R.sup.7 to form a 5- or 6-membered non-aromatic, single or double nitrogen-containing, heterocyclic ring, thus forming a fused ring system; andn is 0 to 3.
