ABSTRACT:
A silver halide photographic light-sensitive material has at least one silver halide emulsion layer on a support. The silver halide emulsion layer contains a silver halide emulsion in which 50% or more of the projected area or the number of all silver halide grains are occupied by substantially perfect cubic silver halide grains, which are silver bromochloroiodide or silver bromoiodide grains having a silver iodide content of 0.5 mol % or more and a silver chloride content of 3 mol % or less and are spectrally sensitized with sensitizing dyes.
