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 hydrogen or a substituted or unsubstituted alkyl or allyl group of from 1 to about 6 carbon atoms, with the proviso that R1 is hydrogen when X is alkoxy; X is R1, an alkoxy group of from 1 to about 4 carbon atoms or taken together with R2 represents the atoms which form a 5- or 6membered heterocyclic ring; R2 is a substituted or unsubstituted alkyl or allyl group of from 1 to about 6 carbon atoms or can be combined with X as described above; 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 or R3.
