摘要

MIXTURE OF DYES FOR MAGENTA DYE DONOR FOR THERMAL COLOR PROOFING A magenta dye-donor element for thermal dye transfer comprises a support having thereon a dye layer comprising a mixture of a yellow dye and a magenta dye dispersed in a polymeric binder, the magenta dye having the formula: wherein: R1 is a substituted or unsubstituted alkyl or allyl group of from 1 to about 6 carbon atoms; X is an alkoxy group of from 1 to about 4 carbon atoms or represents the atoms which when taken together with R2 forms a 5- or 6membered ring; R2 is any of the groups for R1 or represents the atoms which when taken together with X forms a 5- or 6-membered ring; R3 is a substituted or unsubstituted alkyl group of from 1 to about 6 carbon atoms, or a substituted or unsubstituted aryl group of from about 6 to about 10 carbon atoms; J is CO, CO2, -SO2- or CONR5-; R4 is a substituted or unsubstituted alkyl or allyl group of from 1 to about 6 carbon atoms, or a substituted or unsubstituted aryl group of from about 6 to about 10 carbon atoms; and R5 is hydrogen, a substituted or unsubstituted alkyl group of from 1 to about 6 carbon atoms, or a substituted or unsubstituted aryl group of from about 6 to about 10 carbon atoms
