ABSTRACT:
A silver halide photographic material comprising a support having thereon at least one silver halide emulsion layer coated on at least one side of the support. The at least one silver halide emulsion layer comprises a silver halide emulsion containing colloidal silica. 70% or more of the total projected area of all of the silver halide grains contained in the emulsion are tabular grains having an aspect ratio of 3 or more. The mean iodide content of all of the silver halide grains contained in the emulsion is 0.6 mol % or less. The photographic material provides pressure resistance, without lowering the photographic sensitivity of the chemically-sensitized tabular silver halide grains in the emulsion layer.
