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 non-sensitive layer, wherein compound (A) is contained in at least one layer in the silver halide color photosensitive material, compound (A) being a compound capable of releasing compound (Ac1) by oxidation coupling reaction with a color developing agent, compound (Ac1) being a heterocyclic compound which when added, is capable of enhancing the sensitivity of the photosensitive material as compared with that exhibited when not added, provided that the heterocyclic ring of the heterocyclic compound has 1 or 2 hetero atoms.
