A silver halide photographic light-sensitive material is disclosed. The material is comprised of a support having thereon a silver halide emulsion layer containing light-sensitive silver halide grains, at least 10% (in number) of said halide grains being tabular grains having a diameter/thickness ratio of not less than 5. The tabular grains include an iodine-containing silver halide solid solution in an interior portion thereof which is contained in areas covering, with regard to its major or minor axis direction, 80% by mole of the silver contained in the grain. Further, the tabular grains have an average iodine content in the internal high iodine phase which is five times that of the silver bromide, iodobromide or chloroiodobromide contained in the phase present outside of the internal high iodide phase. In addition, the silver contained in the internal high iodine phase is not more than 50% by mole of the total amount of silver in the tabular grains. The photographic material has the advantages inherent to the use of tabular grains and has improved pressure resistant characteristics.
A silver halide photographic light-sensitive material comprising a support having thereon at least one silver halide emulsion layer containing light-sensitive silver halide grains, at least 10% in number of said halide grains being tabular grains having a diameter/thickness ratio of not less than 5, and said tabular silver halide grains satisfying the following conditions:
