Abstract
Abstract 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.
