ABSTRACT:
A silver halide photographic light-sensitive material in which silver halide grains contain rhodium salt and not more than 4 mol % of silver iodide, and at least one of spectral sensitizing dyes represented by formula 1 is added before the commencement of chemical ripening, is disclosed. ##STR1## Z.sub.1 and Z.sub.2 represent ring forming groups with non-metallic atoms i.e. a pyrroline, thiazoline, thiazole, benzothiazole, naphthothiazole, selenazole, benzoselenazole, naphthoselenazole, oxazole, benzooxazole, naphthooxazole, imidazole, benzimidazole or a pyridine group. Each group is unsubstituted or substituted with a halogen atom, a lower alkyl group, a lower alkoxy group or a phenyl group; R.sub.1 and R.sub.2 each represent a lower alkyl group, a hydroxyalkyl group, a carboxylalkyl group or a sulfoalkyl group; R.sub.3, when n.sub.3 is 1, represents a lower alkyl group or a hydrogen atom, while, when n.sub.3 is zero, represents a hydrogen atom; n.sub.1 and n.sub.2 each is 0 or 1; n.sub.3 is 0 or 1; X.sup.- is an anion; and m is 1 or 2.
