Patent ID: 6864216

Claim:
A thermal dye transfer imaging element comprising a magenta dye donor containing a combination of dyes including a magenta dye and a yellow dye exhibiting an RMS error of less than 0.015, wherein the yellow dye is a dye of formula III: wherein: R 11 is an alkyl or allyl group of from 1 to 6 carbon atoms; R 12 is any of the groups as described for R 11 , or represents the atoms which when taken together with R 13 form a 5- or 6-membered ring group; R 13 is an alkyl or alkoxy of from 1 to 6 carbon atoms, or represents the atoms which when taken together with R 12 form a 5- or 6-membered ring group; and R 14 is cyano, C(O)OR 15 , or —CONR 15 R 16 , where R 15 and R 16 each independently represents an alkyl group having from 1 to 6 carbon atoms; a cycloalkyl group of from 5 to 7 carbon atoms; an allyl group; or an aryl group of from 6 to 10 carbon atoms.
