ABSTRACT:
A photographic material, comprising a support having thereon at least one yellow, cyan, and magenta color-forming light-sensitive silver halide emulsion layer, and at least one light-insensitive non-color forming hydrophilic colloid layer. At least one cyan emulsion layer contains a cyan dye-forming coupler [C-1] and at least one light-insensitive colloid layer exists between the support and a light-sensitive emulsion layer most adjacent thereto. Also, a photographic material, comprising a transparent support having thereon at least three kinds of light-sensitive hydrophilic colloid layers each containing any of yellow, magenta and cyan dye-forming couplers and containing silver halide grains different from each other in color sensitivity, and at least one light-insensitive hydrophilic colloid layer. Any layer contains a compound [XI], at least one colloid layer contains a solid fine particle dispersion of a dye [I], and said material has a film pH from 4.6 to 6.4.
