卤化银感光材料

Silver halide photosensitive material
摘要：
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 the following compound (A) is contained in at least one layer of the photosensitive material, and the sensitivity thereof is enhanced by addition compound (A) as compared with that exhibited when not added, compound (A) being a heterocyclic compound having one or more hetero atoms in a ring system, wherein a sensitivity effect (X) at pH of a color developer of 10 and a sensitivity effect (Y) at pH of a color developer of 8 satisfy the following relation: Y/X
摘要（中）：
