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.
