ABSTRACT:
A process of forming a single color, dye ablation image having a reduced D-min comprising imagewise-heating, by means of a laser, a dye-ablative recording element comprising a support having thereon a dye layer comprising an image dye dispersed in a polymeric binder having an infrared-absorbing material associated therewith, the laser exposure taking place through the dye side of the element, and removing the ablated image dye material by means of an air stream to obtain an image in the dye-ablative recording element, wherein the image dye is thermally bleachable and decomposes upon laser exposure.
