Yellow images with improved light stability and yellow dyes useful therein |
abstract |
Disclosed is a dye combination and a thermal dye transfer yellow donor element containing the combination of dyes useful for forming a light stable yellow image comprising a yellow dye having the formula: n n nwherein:n R 1 and R 2 each independently represents an alkyl group of from 1 to 10 carbons atoms or a cycloalkyl group of from 5 to 7 carbon atoms; R 3 and R 4 each independently represents hydrogen, or an unsubstituted lower alkyl group of 1 to 4 carbon atoms; each Y independently represents halogen, or a lower alkyl or alkoxy group of 1 to 4 carbon atoms; and m is 0 to 4.n nSuch a dye combination and element provide improved color and stability, especially for proofing. |
