Claims
- 1. A method for transferring a contrasting pattern of intelligence from a composite LAT imaging film, said composite LAT imaging film comprising:
- a) a support substrate;
- b) at least one intermediate dynamic release layer essentially coextensive therewith comprising a metal, metal oxide or metal sulfide thin film; and
- c) a laser radiation-ablative discontinuous film topcoat essentially coextensive therewith comprising a contrast imaging amount of toner particulates, to a receptor element in contiguous registration therewith, said method comprising the steps of imagewise laser-irradiating said composite LAT imaging film according to such pattern of intelligence with an intensity sufficient to effect the ablation mass transfer of the volume of the imagewise-exposed area of the laser radiation-ablative, discontinuous film topcoat of said composite LAT imaging film onto said receptor element and whereby said transferred topcoat delineates said pattern of intelligence thereon.
- 2. The method as defined by claim 1, wherein said support substrate of the composite LAT imaging film comprises a polyester film.
- 3. The method as defined by claim 1, wherein said discontinuous film ablative topcoat comprises a laser-absorber/sensitizer.
- 4. The method as defined by claim 3, wherein said discontinuous film ablative topcoat comprises an imaging amount of a non-ablation sensitizing contrast imaging material.
- 5. The method as defined by claim 3, wherein said discontinuous film ablative topcoat comprises a non-imaging laser-absorber/sensitizer.
- 6. The method as defined by claim 3, wherein said discontinuous film ablative topcoat comprises at least one near infrared laser-absorber/sensitizer.
- 7. The method as defined by claim 4, wherein said non-ablation sensitizing contrast imaging material comprises a colorant, an ultraviolet or infrared absorbing material, a magnetic material, a polymeric material, a fluorescent material, a conducting material, or mixture thereof.
- 8. The method as defined by claim 4, wherein said non-ablation sensitizing contrast imaging material comprises a yellow, magenta or cyan dye or pigment.
- 9. The method as defined by claim 1, wherein said intermediate dynamic release layer is a metal thin film.
- 10. The method as defined by claim 1, wherein said intermediate dynamic release layer is a metal oxide thin film.
- 11. The method as defined by claim 1, wherein said intermediate dynamic release layer is a metal sulfide thin film.
