Abstract
A dyesheet for light-induced thermal transfer printing comprises a substrate having on one side a dyecoat comprising a polymeric binder containing at least one thermal transfer dye dissolved or dispersed therein, an absorber coat of polymeric material comprising an absorber for the inducing light, and between the dyecoat and the absorber coat an interlayer of organic polymer through which the dye molecules diffuse less readily under printing conditions than they do through the dyecoat binder.
