Abstract
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.
