    摘要： A cyan dye-donor element for thermal dye transfer imaging comprising a support having thereon a dye layer comprising a dye dispersed in a polymeric binder, wherein the dye comprises a mixture of at least three different 2-carbamoyl-4-[N-(p-aminoaryl)-imino]-1,4-naphthoquinone dyes, each of the dyes having the formula: ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 each individually represents a substituted or unsubstituted alkyl group of from 1 to about 6 carbon atoms, a substituted or unsubstituted cycloalkyl group of from about 5 to about 7 carbon atoms, a substituted or unsubstituted aryl group of from about 5 to about 10 carbon atoms or an allyl group;R.sup.2 and R.sup.3 may be combined together to form a 5- or 6-membered ring;R.sup.2 and/or R.sup.3 may be combined with one or two of X to form a 5- or 6-membered ring;R.sup.4 and X each individually represents hydrogen, a substituted or unsubstituted alkyl group of from about 1 to about 6 carbon atoms, halogen, --NHCOR.sup.1 or --NHSO.sub.2 R.sup.1 ; andn represents an integer from 1 to 4;with the proviso that at least one of the dyes is characterized by having R.sup.1 represent an unbranched alkyl group of from 2 to 4 carbon atoms, which may be substituted by an alkoxy group of from 1 to 4 carbon atoms, and/or having one or both of R.sup.2 and R.sup.3 represent a branched alkyl group of from 3 to 6 carbon atoms.
