Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
43 words
An optical recording element comprising a support having coated thereon a layer of an amorphous composition (a) having an absorption factor of at least 20 and (b) comprising a binder and a dye selected from the group consisting of oxoindolizine and oxoindolizinium dyes.
Claim 2
Dependent Claim
43 words
An optical recording element comprising a support having coated thereon a layer of an amorphous composition (a) having an absorption factor of at least 20 and (b) comprising a binder and a dye selected from the group consisting of oxoindolizine and oxoindolizinium dyes.
Claim 3
Dependent Claim
151 words
The element of claim 1 wherein the layer absorbs in the 750-900 nm region of the spectrum and the oxoindolizine and oxoindolizinium dyes, in their keto form, have the structures: ##STR2## wherein R 1 and R 2 are individually selected from the group consisting of alkyl containing 1 to 18 carbon atoms; aryl containing 6 to 20 carbon atoms; and polystyryl having appended groups selected from the group consisting of indolizine and indolizinium groups and combinations thereof; R 3 is a divalent group which, with structure I completes an organic chromophore; R 4 and R 5 are individually hydrogen, chlorine, bromine, alkyl containing 1 to 18 carbon atoms; cyano; acyl containing 2 to 18 carbon atoms; carboalkoxy containing 1 to 18 carbon atoms; aminocarbonyl or acyloxy containing 2 to 18 carbon atoms; R 6 is a monovalent group which with structure II completes an organic chromophore; and X is an anion.
