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