Abstract
A marking transfer sheet comprising an imaging layer of pigment, binder and a color-forming, radiation-sensitive component on a carrier film and a process for its use comprising exposing the imaging layer to a pattern of radiation to form a mark, heating the imaging layer until adhesive, and contacting the imaging layer with a support more adherent to the imaging layer than the carrier film; and optionally separating the carrier film from the imaging layer.
