Silver halide color photographic material
摘要:
There is disclosed a silver halide color photographic material having a red-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer, a blue-sensitive silver halide emulsion layer, which comprises a cyan dye-forming coupler represented by formula (I) and (a) a monodisperse silver halide emulsion, (b) non-photosensitive silver halide emulsion wherein the inside or the surface of grains is fogged, (c) a colloidal silver, (d) negative-type interval latent image-type silver halide grains chemically sensitized to a defined depth from the surface, (e) a sensitizing dye containing a sulfonamide group, (f) three separated layers of high, medium, and low sensitivities, (g) two separated layers each having different content of iodine, (h) grains each having a defined spectral sensitivity distribution and a DIR-hydroquinone, or (i) a DIR-hydroquinone: formula (I) ##STR1## wherein R.sup.1 represents a hydrogen atom or a substituent, R.sup.2 represents a substituent, X represents a hydrogen atom or a group capable of being released upon a coupling reaction of the coupler represented by formula (I) with the oxidized product of a color-developing agent, and Z.sup.1 represents a group of nonmetallic atoms required for forming a nitrogen-containing 6-membered heterocyclic ring, which contains at least one group capable of being dissociated.
