ABSTRACT:
A silver halide color photosensitive material comprising a support and, superimposed thereon, a blue-sensitive layer unit, a green-sensitive layer unit and a red-sensitive layer unit, each of these light-sensitive layer units composed of at least one silver halide emulsion layer, together with at least one nonphotosensitive layer, wherein at least one compound (A) and at least one compound (B) are contained, the compound (A) being a heterocyclic compound of less than 4.5 C log P which when added, is capable of enhancing the sensitivity of the silver halide color photosensitive material as compared with that exhibited when not added, the compound (B) being a heterocyclic compound of 4.5 or greater C log P which when added, is capable of enhancing the sensitivity of the silver halide color photosensitive material as compared with that exhibited when not added.
