Abstract
A reversal photographic element comprising at least two dye image-forming units, at least one unit comprising (1) a first silver halide emulsion layer spectrally sensitized to a given region of the spectrum with which is associated a dye image-forming chromogenic coupler and (2) a second silver halide emulsion layer spectrally sensitized to a different region of the spectrum than the first and containing an interimage effect-forming means such as a development inhibitor-releasing coupler, which forms either a colorless compound or a dye which does not substantially take part in the formation of the image.
Claims14
A color image-forming silver halide reversal photographic element comprising at least two dye image-forming units, each unit containing at least one photosensitive silver halide layer and a dye image-former, wherein at least one of the dye image-forming units comprises
- (1) a first silver halide emulsion layer spectrally sensitized to a given region of the spectrum with which is associated a dye-forming coupler and
- (2) a second halide emulsion layer spectrally sensitized to a different region of the spectrum than the first and containing an interimage effect-forming means comprising a development inhibitor-releasing compound or coupler which, upon color development, forms either a colorless compound or a dye which does not substantially take part in the formation of the image, said second silver halide emulsion layer not having a dye-forming coupler which substantially takes part in the formation of the image.
