Abstract
The present invention concerns a color reversible photographic product In particular, the present invention concerns a new photographic product which has a increase in the exposure latitude of one of the silver halide emulsion layers with which a dye-forming coupler is associated without changing the chromatic balance. This increase in the exposure latitude makes it possible to improve the details of the dye image.
Claims10
Color reversible photographic product comprising a support, at least one blue-sensitive silver halide emulsion layer, with which a yellow dye-forming coupler is associated, at least one green-sensitive silver halide emulsion layer, with which a magenta dye-forming coupler is associated, and at least one red-sensitive silver halide emulsion layer, with which a cyan dye-forming coupler is associated, each coupler being present in a ratio to the quantity of silver enabling a dye image with a maximum density (Dmax) of at least 2 to be obtained, wherein a part of the quantity of one of the dye-forming couplers necessary for the formation of this dye image with a Dmax of at least 2 is introduced into one of the emulsion layers other than that with which the coupler is associated, the silver content of these layers being modified in order to maintain the same ratio between the quantity of couplers and the quantity of silver and in that the emulsions of each of the sensitive layers are chosen so that the photographic product has no inter-image effect.
