Abriebfeste Überzugschicht zur ablativen Abbildung mittels Laser

摘要

A laser dye-ablative recording element comprising a support having thereon, in order, a dye layer comprising an image dye dispersed in a polymeric binder and a polymeric overcoat which contains polytetrafluoroethylene beads but which does not contain any image dye, the dye layer having an infrared-absorbing material associated therewith to absorb at a given wavelength of the laser used to expose the element, the image dye absorbing in the region of the electromagnetic spectrum of from about 300 to about 700 nm and not having substantial absorption at the wavelength of the laser used to expose the element.
