发明名称 Silver halide color photographic material including a silver halide of small grain size
摘要 A color photographic material having at least one red-sensitive silver halide emulsion layer, at least one green-sensitive silver halide emulsion layer and at least one blue-sensitive silver halide emulsion layer, characterized in that a blue-sensitive silver halide emulsion which is used in at least one of the blue-sensitive silver halide emulsion layer or layers contains silver halide grains of an average size of 0.4 mu or less and at least one sensitizing dye represented by formula I or II: <IMAGE> [I] <IMAGE> [II] wherein Z1, Z2 and Z3 each represent an atomic group necessary for completing an oxazole, benzoxazole, naphthoxazole, thiazole, benzothiazole, naphthothiazole, imidazole, benzimidazole or naphthoimidazole ring; R1, R2, R3 and R4 each represent a substituted or unsubstituted alkyl or aryl group; (X-) represents an acid anion; and n represents zero or 1. The photographic material is excellent in sensitivity, graininess, sharpness and storage stability, and gives an excellent color reproduction without color mixing.
