Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
52 words
A laser dye-ablative recording element comprising a support having thereon a dye layer comprising two or more image dyes dispersed in a polymeric binder, said dye layer having an infrared-absorbing material associated therewith, and wherein said image dyes comprise a curcumin yellow dye having the formula: ##STR5## and a 1,4-diamino anthraquinone dye.
Claim 2
Dependent Claim
52 words
A laser dye-ablative recording element comprising a support having thereon a dye layer comprising two or more image dyes dispersed in a polymeric binder, said dye layer having an infrared-absorbing material associated therewith, and wherein said image dyes comprise a curcumin yellow dye having the formula: ##STR5## and a 1,4-diamino anthraquinone dye.
Claim 3
Dependent Claim
13 words
The element of claim 1 wherein said dye layer contains an ultraviolet-absorbing dye.
Claim 4
Dependent Claim
19 words
The element of claim 1 wherein said infrared-absorbing material is a dye which is contained in said dye layer.
Claim 5
Dependent Claim
40 words
The element of claim 1 wherein said anthraquinone dye has the formula: ##STR6## wherein R 1 and R 2 each independently represents hydrogen, alkyl, alkenyl, cycloalkyl, haloalkyl, cyanoalkyl, alkoxyalkyl, alkoxyalkoxyalkyl, hydroxyalkyl, hydroxyalkoxyalkyl, hydroxyalkylthioalkyl, tetrahydrofurfuryl, alkenyloxyalkyl, tetrahydrofurfuryloxyalkyl, alkoxycarbonykalkyl, alkoxycarbonyloxyalkyl or alkoxycarbonyloxyalkyl.
Claim 6
Dependent Claim
17 words
The element of claim 4 wherein R 1 and R 2 each independently represents alkyl or aryl.
Claim 7
Dependent Claim
96 words
A process of forming a dye ablation image having an improved Dmin comprising imagewise-heating by means of a laser, a dye-ablative recording element comprising a support having thereon a dye layer comprising two or more image dyes dispersed in a polymeric binder, said dye layer having an infrared-absorbing material associated therewith, 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 image dyes comprise a curcumin yellow dye having the formula: ##STR7## and a 1,4-diaminoanthraquinone dye.
Claim 8
Dependent Claim
96 words
A process of forming a dye ablation image having an improved Dmin comprising imagewise-heating by means of a laser, a dye-ablative recording element comprising a support having thereon a dye layer comprising two or more image dyes dispersed in a polymeric binder, said dye layer having an infrared-absorbing material associated therewith, 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 image dyes comprise a curcumin yellow dye having the formula: ##STR7## and a 1,4-diaminoanthraquinone dye.
Claim 9
Dependent Claim
13 words
The process of claim 6 wherein said dye layer contains an ultraviolet-absorbing dye.
Claim 10
Dependent Claim
19 words
The process of claim 6 wherein said infrared-absorbing material is a dye which is contained in said dye layer.
Claim 11
Dependent Claim
40 words
The process of claim 6 wherein said anthraquinone dye has the formula: ##STR8## wherein R 1 and R 2 each independently represents hydrogen, alkyl, alkenyl, cycloalkyl, haloalkyl, cyanoalkyl, alkoxyalkyl, alkoxyalkoxyalkyl, hydroxyalkyl, hydroxyalkoxyalkyl, hydroxyalkylthioalkyl, tetrahydrofurfuryl, alkenyloxyalkyl, tetrahydrofurfuryloxyalkyl, alkoxycarbonykalkyl, alkoxycarbonyloxyalkyl or alkoxycarbonyloxyalkyl.
Claim 12
Dependent Claim
17 words
The process of claim 9 wherein R 1 and R 2 each independently represents alkyl or aryl.
