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 ##STR1## wherein R.sup.1, R.sup.2, and R.sup.5 are substituted or unsubstituted alkyl, cycloalkyl, or aryl; and R.sup.3 and R.sup.4 are hydrogen; substituted or unsubstituted alkyl; halogen; --NHCOR.sup.1 or --NHSO.sub.2 R.sup.1.
Claims20
A cyan dye-donor element for thermal dye transfer comprising a support bearing a dye layer comprising a cyan dye dispersed in a polymeric binder, said cyan dye comprising a 2-carbamoyl-4-[N-(p-substituted aminoaryl)imino]-1,4-naphthoquinone.
In a process of forming a cyan dye transfer image comprising imagewise-heating a dye-donor element comprising a support bearing a dye layer comprising a cyan dye dispersed in a polymeric binder and transferring a cyan dye image to a dye-receiving element to form said cyan dye transfer image, the improvement wherein said cyan dye comprises a 2-carbamoyl-4-[N-(p-substituted aminoaryl)imino]-1,4-naphthoquinone.
In a thermal dye transfer assemblage comprising:
- (a) a cyan dye-donor element comprising a support bearing a dye layer comprising a cyan dye dispersed in a polymeric binder, and
- (b) a dye-receiving element comprising a support bearing a dye image-receiving layer,
- said dye-receiving element being in a superposed relationship with said cyan dye-donor element so that said dye layer is in contact with said dye image-receiving layer, the improvement wherein said cyan dye comprises a 2-carbamoyl-4-[N-(p-substituted aminoaryl)imino]-1,4-naphthoquinone.
