| titleOfInvention | Direct reversal photographic color material |
| abstract | A color photographic material suitable for processing with an alkaline solution in the presence of a developing agent is described, comprising a support and, in sequence, the following five layers: (1) a first emulsion layer containing an internal latent image forming direct reversal silver halide emulsion that is selectively sensitive to light in a first spectral region; (2) a first color material layer containing a ballasted dye releasing redox compound that provides a dye image that selectively absorbs light in the first spectral region; (3) an intermediate layer containing a ballasted reducing agent that captures an oxidized developing agent or electron transfer agent; (4) a second emulsion layer containing an internal latent image forming direct reversal silver halide emulsion that is selectively sensitive to light in a second spectral region; and (5) a second color material layer containing a ballasted dye releasing redox compound that provides a dye image that selectively absorbs light in the second spectral region. The improvement is that a surface latent image forming negative silver halide emulsion that is sensitive to light in the second spectral region is uniformly incorporated in the intermediate layer (3) so as to make uniform the distribution of oxidation of said reducing agent that is formed in the intermediate layer (3) as a result of development of the second emulsion layer. |
