The present invention relates to a cyan dye donor element for thermal transfer imaging comprising a support having thereon a dye layer comprising a mixture of at least two cyan dyes dispersed in a polymeric binder, wherein at least one of the at least two cyan dyes is a light stabilizing dye represented by Formula I and a thermal image recording method utilizing the same cyan dye donor element, wherein R1 and R2 are substituted or unsubstituted alkyl, cycloalkyl, or aryl, or combine to form a carbocyclic or heterocyclic ring; R3 is hydrogen, halogen, alkoxy, substituted or unsubstituted alkyl, NHCOR1, NHSO2R1, or combine s with either R1 or R2 to form a carbocyclic or heterocyclic ring; X is halogen; Y is alkyl; Z is carbon or nitrogen; J is NHCOR4; R4 is R5Phenyl(OR7)m; R5 is -(CHR6)n- or -(CH2)pO-; R6 is hydrogen, substituted or unsubstituted alkyl; R7 is substituted or unsubstituted alkyl, carbocycle or heterocycle; m is 2-5; n is 0-6; p is 2-5; the formula weight of R4 does not exceed 230. The present invention also relates to a cyan ink-jet dye comprising a light stabilizing cyan dye represented by Formula I. The experimental process involved the reaction of N,N-DIethyl-6-methyl-5-nitro-2-pyridinamine(cas: 28489-43-2).Related Products of 28489-43-2
