Claims
- 1. A photographic element comprising a support having thereon a hydrophilic colloid layer comprising infrared-sensitive silver halide and a hydrophilic colloid layer, which is the same as or different from said silver halide layer, comprising an amount effective as a photographic filter dye of a compound having the formula: ##STR14## wherein: R.sub.1 and R.sub.2 each independently represents sulfoalkyl carboxyalkyl, or sulfatoalkyl containing 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 of each Z ring and the carboxy group,
- R.sub.3 and R.sub.5 are each hydrogen or together represent the atoms necessary to complete a 5- or 6-membered carbocyclic ring,
- R.sub.4 represents hydrogen, alkyl of 1 to 4 carbon atoms, aryl, cyano, halogen, or ##STR15## where R.sub.6 and R.sub.7 each independentlly 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 heterocyclic ring,
- X.sup..sym. represents a cation, and
- Z.sub.1 and Z.sub.2 each independently represents the atoms that complete an indole, naphthindole or benzindole nucleus.
- 2. A photographic element according to claim 1 wherein the dye is present in an amount of from 0.1 to 500 mg/ft.sup.2.
- 3. A photographic element according to claim 1 further comprising, in the layer comprising the dye, a compound capable of deaggregating the dye, in an amount sufficient to deaggregate the dye.
- 4. A photographic element according to claim 3 wherein the dye is present in an amount of from 0.1 to 500 mg/ft.sup.2 and wherein the deaggregating compound is present in an amount of from 25 to 10,000 weight percent, based on the weight of the dye.
- 5. A photographic element according to any of claims 1-4 wherein the dye has the structure: ##STR16## wherein X.sym., R1, R2, R3, R4, and R5, are as defined in claim 1, R.sub.8, R.sub.9, R.sub.10 and R.sub.11 each independently represent methyl or ethyl, or
- R.sub.8 and R.sub.9 or R.sub.10 and R.sub.11, taken together with the carbon atoms to which they are attached, may form a cycloalkyl group.
- 6. A photographic element according to claim 5 wherein the dye is in the silver halide layer.
- 7. A photographic element according to claim 5 wherein the dye isan antihalation dye present in a layer other than the silver halide layer.
- 8. A photographic element according to claim 3 or 4 wherein the deaggregating compound is selected from the group consisting of:
- 4,4'-bis[4,6-bis-(2-chloroanilino-s-triazin-2-yl)-amino[-2,2'-stilbenedisulfonic acid, disodium salt,
- bis[3-methyl-1-(p-sulfophenyl)-2-pyrazolin-5-one-(4)]methineoxonol,
- bis[3-methyl-1-(p-sulfophenyl)-2-pyrazolin-5-one-(4)]pentamethineoxonol,
- bis[3-methyl-1-(p-sulfophenyl)-2-pyrazolin-5-one(4)]trimethineoxonol disodium salt, and
- bis(1-butyl-3-carboxymethyl-5-barbituric acid)trimethineoxonol.
