Abstract
Abstract There is disclosed a light-sensitive silver halide photographic material, having two or more light-sensitive silver halide emulsion layers different in color sensitivities on a support, at least two of the light-sensitive silver halide emulsion layers different in color sensitivities containing a DIR compound capable of releasing a developing inhibitor or developing inhibitor precursor through the reaction with the oxidized product of a developing agent, the developing inhibitor or developing inhibitor precursor released from the DIR compound being diffusive, wherein the following conditions A: DIR compounds are added and incorporated in the emulsion layers so that the developing inhibitor released from the DIR compound incorporated in one color-sensitive silver halide emulsion layer and the developing inhibitor released from the DIR compound incorporated in the other color-sensitive silver halide emulsion layer are reversed in developing inhibiting power when the DIR compounds to be incorporated in the respective light-sensitive silver halide emulsion layers are exchanged with each other, and also each DIR compound may have greater inhibiting power for the other light-sensitive silver halide emulsion layer rather than for the light-sensitive silver halide emulsion layer in which it is incorporated, is satisfied for the at least two light-sensitive silver halide emulsion layers different in color sensitivities.
