Abstract
Abstract A silver halide color photographic light-sensitive material is described, which is of ultra-high-sensitivity and is characterized by having the following light-sensitive layer unit (I), (II) or (III): Unit (I): a light-sensitive layer unit comprising: (a) a blue- and green-sensitive layer containing (a-1) a yellow image-forming coupler, (a-2) a magenta image-forming coupler, and (a-3) a cyan colored coupler; and (b) a green- and red-sensitive layer containing (b-1) a cyan image-forming coupler, (b-2) a magenta image-forming coupler, and (b-3) a yellow colored coupler. Unit (II): a light-sensitive layer unit comprising: (a) a blue- and red-sensitive layer containing (a-1) a yellow image-forming coupler, (a-2) a cyan image-forming coupler, and (a-3) a magenta colored coupler; and (b) a green- and red-sensitive layer containing (b-1) a magenta image-forming coupler, (b-2) a cyan image-forming coupler, and (b-3) a yellow colored coupler. Unit (III): a light-sensitive layer unit comprising: (a) a blue- and green-sensitive layer containing (a-1) a magenta image-formula coupler, (a-2) a yellow image-forming coupler, and (a-3) a cyan colored coupler; and (b) a blue- and red-sensitive layer containing (b-1) a cyan image-forming coupler, (b-2) a yellow image-forming coupler, and (b-3) a magenta colored coupler.
