Disclosed is a thermal dye transfer imaging donor element and a dye combination comprising a combination of dyes including a magenta dye and a yellow dye exhibiting an RMS error of less than 0.015.

Thermal magenta donor and dyes

Disclosed is an imaging element comprising a bichromophoric molecule comprising a first chromophore that exhibits a first absorption maximum above 700 nm and a second chromophore that exhibits a second absorption maximum different from the first absorption maximum, wherein the absorption of the first and second chromophores are substantially independent of each other, and a process for imaging using such a donor element. Elements of the invention eliminate unwanted absorptions in the final image.

Thermal transfer imaging element containing infrared bichromophoric colorant

Disclosed is a molecule containing a first chromophore that exhibits a first absorption maximum above 700 nm and a second chromophore that exhibits a second absorption maximum different from the first absorption maximum, wherein the absorption of the first and second chromophores are substantially independent of each other. The molecule exhibits improved stability.
