Silver halide photographic material.

摘要

A silver halide photographic material having a high covering power with improved pressure resistance and antistatic properties upon development, which comprises at least one silver halide photographic emulsion layer disposed on at least one side of a support, wherein at least one of the silver halide photographic emulsion layer(s) contains a photosensitive silver halide emulsion containing silver iodide and an internally fogged silver halide emulsion, and at least one of the silver halide photographic emulsion layer(s) and an auxiliary layer(s) which is disposed on the same side of the support as that of the support having said emulsion containing silver iodide contains at least one polyoxyethylenic surface active agent selected from the group consisting of compounds represented by formula (I) and (II)
