Abstract
There is disclosed a light-sensitive photographic material which comprises a silver halide emulsion layer containing a first coupler dispersed in oil droplets, a second coupler dispersed in an alkali aqueous solution and a compound capable of releasing a diffusible development inhibiting substance or a precursor thereof. The specified combination of the first and the second couplers with the diffusible DIR coupler according to the present invention provide a good inter image effect whereby color images having excellent color balance are obtained. The first coupler is preferably selected from compounds of the formula (II), (III), (IV), (V), (VI), (VII) (VIII) which contain at least one lipophilic substituent; and the second coupler is preferably selected from compounds of the formula (IV), (V), (VI), (VII), or (VIII) which do not contain a lipophilic substituent: ##STR1##
