ABSTRACT:
A silver halide color photosensitive material of less than 320 ISO speed, comprising at least two red-sensitive emulsion layers, at least two green-sensitive emulsion layers, at least one blue-sensitive emulsion layer and at least one nonsensitive layer, wherein silver halide tabular grains of 0.15 μm or less grain thickness are contained in an amount of 50% or more in respective layers with the highest speed among the green- and red-sensitive emulsion layers; wherein the total dry film thickness of the material on the emulsion layer side thereof is 24 μm or less; and wherein the compound (A) is contained in at least one silver halide emulsion layer or the nonsensitive layer.Compound (A): heterocyclic compound having one or more heteroatoms, which heterocyclic compound is capable of substantially increasing the sensitivity of silver halide color photosensitive material by addition thereof as compared with that exhibited when the compound is not added.
