Abstract
There is disclosed a light-sensitive silver halide color photographic material having red-sensitive, green-sensitive and blue-sensitive emulsion layers, each layer consisting of two or more layers with different sensitivities on a support, wherein the layers are constituted so as to satisfy the following requirements (A), (B), (C) and (D): (A) of the respective emulsion layers having the highest sensitivities among the the red-sensitive, green-sensitive and blue-sensitive emulsion layers, the highest sensitivity blue-sensitive emulsion layer is provided on the side farthest from the support; (B) at least the the highest sensitivity red-sensitive emulsion layer and the highest sensitivity green-sensitive emulsion layer are provided between the the highest blue-sensitive emulsion layer and a blue-sensitive emulsion layer with lower sensitivity; (C) none of the respective red-sensitive, green-sensitive and blue-sensitive emulsion layers having the lowest sensitivities exists on the side farther than the low sensitivity blue-sensitive emulsion layer from the support; and (D) contained in at least one layer of the high sensitivity red-sensitive, green-sensitive and blue-sensitive layers, is a diffusion-resistant compound capable of forming a mobile dye through the coupling reaction with the oxidized product of a chromogenic developing agent. The light-sensitive material according to this invention exhibits excellent photographic characteristics such as graininess, sharpness and sensitivity.
