Silver halide photographic light-sensitive materials.

摘要

A silver halide photographic light-sensitive material is disclosed having a silver halide emulsion layer comprised of silver halide grains which contain at least silver chloride and which have been spectrally sensitized to infrared using at least one tricarbocyanine dye and/or dicarbocyanine dye which contains a 4-quinoline nucleus, wherein there is at least one hydrophilic colloid layer which contains at least one dye which is represented by general formula (F-I) indicated below and at least one dye which is represented by general formula (F-II) indicated below: <CHEM> wherein R<1>, R<2>, R<3>, R<4>, R<5> and R<6>, which may be the same or different, each represents a substituted or unsubstituted alkyl group; Z<1> and Z<2> each represents a group of non-metal atoms which is required to form a substituted or unsubstituted benzo-condensed ring, naphtho-condensed ring or five or six membered heterocyclic condensed ring; provided that R<1>, R<2>, R<3>, R<4>, R<5>, R<6>, Z<1> and Z<2> are groups such that the dye molecule has at least three acid groups; L<1>, L<2> and L<3> represent substituted or unsubstituted methine groups; X represents an anion; and n is 1 or 2, and n is 1 when the dye forms an intramolecular salt, <CHEM> wherein R21 and R24 each represents a hydrogen atom, an aliphatic group, an aromatic group or a heterocyclic group; R22 and R25 each represents a hydrogen atom, an aliphatic group, an aromatic group, a heterocyclic group, COR29 or SO2R29; R23 and R26 each represents a hydrogen atom, a cyano group, an alkyl group, an aryl group, -COOR27, -OR27, -NR27R28, -N(R28)COR29, represents an aliphatic group or an aromatic group and R27 and R28 each represents a hydrogen atom, an aliphatic group or an aromatic group); L4, L5, L6, L7 and L8 represent methine groups; n1 and n2 each represents 0 or 1; and M<(+)> represents hydrogen or some other univalent cation; provided that at least one of R21, R22, R23, R24, R25, R26, L4, L5, L6, L7 or L8 represents a group which has at least one carboxylic acid group or sulfonic acid group.
