摘要

A cyan dye-donor element for thermal dye transfer comprises a support having thereon a cyan dye dispersed in a polymeric binder, the cyan dye comprising a 2-carbamoyl-4-[N-(p-substituted aminoaryl)imino]-1,4-naphthoquinone. In a preferred embodiment, the cyan dye has the formula wherein R1, R2, and R5 are substituted or unsubstituted alkyl, cycloalkyl, or aryl; and R3 and R4 are hydrogen; substituted or unsubstituted alkyl; halogen; -NHCOR1 or -NHSO2R1.
