摘要:
A multilayer silver halide color photographic material is described, comprising a support having thereon at least two light-sensitive silver halide emulsion layers, each having a different color sensitivity, and having associated therewith dye-forming agents forming imaging dyes, each having a different hue, wherein at least one dye of a hue substantially not contributing to the formation of the hue of a specific image of a region that the image density of at least one of said imaging dyes is above a definite density value of from 1.2 to 2.5 is provided so as to provide gradation to the specific image region.
