Abstract
Abstract A process of forming a single color, dye ablation image having an improved 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 and an infrared-absorbing material, the laser exposure taking place through the dye side of the element, and removing the ablated image dye material to obtain an image in the dye-ablative recording element, and wherein the element contains an interlayer containing infrared-absorbing material and which is located between the support and the dye layer.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
99 words
A process of forming a single color, dye ablation image having an improved 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 and an infrared-absorbing material, said laser exposure taking place through the dye side of said element, and removing the ablated image dye material to obtain said image in said dye,ablative recording element, wherein said element also contains an interlayer containing poly(vinyl alcohol) and an infrared-absorbing material and which is located between said support and said dye layer.
Claim 2
Dependent Claim
99 words
A process of forming a single color, dye ablation image having an improved 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 and an infrared-absorbing material, said laser exposure taking place through the dye side of said element, and removing the ablated image dye material to obtain said image in said dye,ablative recording element, wherein said element also contains an interlayer containing poly(vinyl alcohol) and an infrared-absorbing material and which is located between said support and said dye layer.
Claim 3
