Page 9, (2008/06/13)
Disclosed are analogues of trimethine cyanine dyes which are useful for imparting fluorescent properties to target materials by covalent and non-covalent association. The compounds have the following general formula: optionally substituted by groups R2-R9 wherein groups R6, R7, R8 and R9 are attached to the rings containing X and Y or, optionally are attached to atoms of the Za and Zb ring structures and groups R1-R9 are chosen to provide desired solubility, reactivity and spectral properties to the fluorescent compounds; A is selected from O, S and NR11 where R11 is the substituted amino radical: where R′ is selected from hydrogen, a C1-4 alkyl and aryl and R″ is selected from C1-18 alkyl, aryl, heteroaryl, an acyl radical having from 2-7 carbon atoms, and a thiocarbamoyl radical; Za and Zb each represent a bond or the atoms necessary to complete one, two fused or three fused aromatic rings each ring having five or six atoms, selected from carbon atoms and, optionally, no more than two oxygen, nitrogen and sulphur atoms.

-
, (2008/06/13)
A compound, useful as an infrared absorbing dye, having the structure: is disclosed for use in photographic elements. In this formula, R1 and R2 each independently represents sulfoalkyl, carboxyalkyl, or sulfatoalkyl of from 3 to 6 carbon atoms, having at least 3 carbon atoms in the alkyl chain between the nitrogen atom of each Z ring and the sulfo or sulfato group, and at least 2 carbon atoms in the alkyl chain between the nitrogen atom of each Z ring and the carboxy group., R3 and R5 are each hydrogen or together represent the atoms necessary to complete 5- or 6-membered carbocyclic ring, and R4 represents hydrogen, alkyl of 1 to 4 carbon atoms, aryl, cyano, halogen, or , where R6 and R7 each independently represents alkyl of from 1 to 6 carbon atoms or aryl, or together represent the non-metallic atoms necessary to form a 5- or 6-membered ring., X⊕ represents a cation., Z1 and Z2 each independently represent the atoms needed to complete an indole, naphthindole or benzindole nucleus
