摘要：
A silver halide photographic light-sensitive material is disclosed which comprises a support and, provided thereon, a silver halide emulsion layer comprising silver halide grains having a surface phase and an internal phase adjacent to said surface phase. The internal phase has a thickness of 100 .ANG., and the silver iodide content of the surface phase is higher than that of the internal phase.
