摘要：
A silver halide photographic emulsion which contains silver halide grains and spectral sensitizing dyes in a total amount equivalent to 160% or more of a saturated coated amount of the silver halide grains. The spectral sensitizing dyes include at least one spectral sensitizing dye represented by formula (1) and formula (2) multi layer adsorbed onto a surface of the silver halide grains in an amount equivalent to 80% or more of the saturated coated amount of the silver halide grains:
