摘要:
A silver halide light sensitive photographic material is disclosed, comprising a support having thereon hydrophilic colloid layers including a silver halide emulsion layer, wherein (i) at least 50% of the total projected area of silver halide grains contained in the emulsion layer is accounted for by tabular grains having an aspect ratio of 3 to 15, (ii) the tabular grains each comprising an inner region which accounts for 70% by volume of the grain and a residual outer region, the outer region containing at least 75% of total iodide contained in the grain, and (iii) the tabular grains each having an outermost layer, a halide content distribution among the tabular grains with respect to the outermost layer being not more than 20%; and wherein at least one of the hydrophilic colloid layers contains a sulfur containing compound, which has a water-solubilizing group.
