Abstract (en)
[origin: EP0438791A1] A silver halide photographic light-sensitive material includes at least one silver halide emulsion layer containing a silver halide emulsion prepared by adding at least one compound represented by the following general formula [I], [II], or [III] during a manufacturing process, wherein at least 50% of a total projected area of all silver halide grains of the emulsion layer are occupied by tabular silver halide grains consisting of silver iodobromide, silver iodochloride, or silver iodochlorobromide each containing not less than 3.0 mol% of silver iodide on an average, an aspect ratio of the tabular silver halide grains occupying at least 50% of the total projected area is 3.0 or more, and a relative standard deviation between silver iodide contents of individual grains is not more than 30%: [I] R-SO2S-M [II] R-SO2S-R<1> [III] R-SO2S-Lm-SSO2-R<2> wherein R, R<1>, and R<2> may be the same or different and independently represent an aliphatic group, an aromatic group, or a heterocyclic group, M represents a cation, L represents a divalent linking group, and m represents 0 or 1. Compounds represented by general formulas [I] to [III] may be polymers containing divalent groups derived from structures represented by general formulas [I] to [III] as repeating units. If possible, R, R<1>, R<2>, and L may be bonded to each other to form a ring. r
