Abstract
Disclosed is a direct positive silver halide color photographic light-sensitive material comprising a support and provided thereon, a blue-sensitive emulsion layer containing previously unfogged internal latent image-forming silver halide grains having a spectral sensitivity to blue-light, a green-sensitive emulsion layer containing previously unfogged internal latent image-forming silver halide grains having a spectral sensitivity to green-light, a red-sensitive emulsion layer containing previously unfogged internal latent image-forming silver halide grains having a spectral sensitivity to red-light and a hydrophilic colloidal layer, wherein said blue-sensitive emulsion layer is provided so as to be located farther than both said green-sensitive and said red-sensitive emulsion layers from the support; and at least one of said blue-sensitive emulsion layer, said-green sensitive emulsion layer and said red-sensitive emulsion layer or said hydrophilic colloidal layer contains an internal latent image forming silver halide grains having a spectral sensitivity having a part common to the respective spectral sensitivity regions pertaining to said blue-sensitive emulsion layer, said green-sensitive emulsion layer and said red-sensitive emulsion layer; and said spectral sensitivity of said blue-sensitive emulsion layer to said blue-light, is not less than 0.8 of at least one selected from a spectral sensitivity of said green-sensitive emulsion layer to said blue-light or a spectral sensitivity of said red-sensitive emulsion layer to blue-light.
