Abstract
Abstract 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 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 is substantially transparent in the infrared region of the electromagnetic spectrum and absorbs in the region of from about 300 to about 700 nm and does not have substantial absorption at the wavelength of the laser used to expose the element.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
116 words
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 does not contain any image dye, said dye layer having an infrared-absorbing material associated therewith to absorb at a given wavelength of the laser used to expose said element, said image dye being substantially transparent in the infrared region of the electromagnetic spectrum and absorbing in the region of from about 300 to about 700 nm and not having substantial absorption at the wavelength of the laser used to expose the element, said overcoat layer being coated at about 0.1 to about 5 g/m 2 of element.
Claim 2
Dependent Claim
116 words
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 does not contain any image dye, said dye layer having an infrared-absorbing material associated therewith to absorb at a given wavelength of the laser used to expose said element, said image dye being substantially transparent in the infrared region of the electromagnetic spectrum and absorbing in the region of from about 300 to about 700 nm and not having substantial absorption at the wavelength of the laser used to expose the element, said overcoat layer being coated at about 0.1 to about 5 g/m 2 of element.
Claim 3
Dependent Claim
12 words
The element of claim 1 wherein said infrared-absorbing material is a dye.
Claim 4
Dependent Claim
15 words
The element of claim 1 wherein said infrared-absorbing material is contained in said dye layer.
Claim 5
Dependent Claim
10 words
The element of claim 1 wherein said support is transparent.
Claim 6
Dependent Claim
18 words
The element of claim 1 wherein a barrier layer is present between said support and said dye layer.
Claim 7
Dependent Claim
21 words
The element of claim 1 wherein said polymeric overcoat is a polyurethane, cellulose nitrate, cellulose acetate propionate, gelatin or a polyacrylate.
Claim 8
Dependent Claim
171 words
A process of forming a single color, ablation image having an improved scratch resistance comprising imagewise heating by means of a laser, in the absence of a separate receiving element, a 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 does not contain any image dye, said dye layer having an infrared-absorbing material associated therewith to absorb at a given wavelength of said laser used to expose said element, said image dye being substantially transparent in the infrared region of the electromagnetic spectrum and absorbing in the region of from about 300 to about 700 nm and not having substantial absorption at the wavelength of said laser used to expose said element, said laser exposure taking place through the dye side of said element, said overcoat layer being coated at about 0.1 to about 5 g/m 2 of element and removing the ablated material to obtain an image in said ablative recording element.
Claim 9
Dependent Claim
171 words
A process of forming a single color, ablation image having an improved scratch resistance comprising imagewise heating by means of a laser, in the absence of a separate receiving element, a 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 does not contain any image dye, said dye layer having an infrared-absorbing material associated therewith to absorb at a given wavelength of said laser used to expose said element, said image dye being substantially transparent in the infrared region of the electromagnetic spectrum and absorbing in the region of from about 300 to about 700 nm and not having substantial absorption at the wavelength of said laser used to expose said element, said laser exposure taking place through the dye side of said element, said overcoat layer being coated at about 0.1 to about 5 g/m 2 of element and removing the ablated material to obtain an image in said ablative recording element.
Claim 10
Dependent Claim
12 words
The process of claim 7 wherein said infrared-absorbing material is a dye.
Claim 11
Dependent Claim
15 words
