ABSTRACT:
The present invention concerns a photographic product containing at least one light-sensitive layer consisting of a blend of silver halide emulsions.
The blend of the invention is formed by at least one pure bromide emulsion, the proportion of fast emulsion grains in the blend is less than 50% compared with the total number of silver halide grains, and the proportion of slow emulsion grains in the blend is greater than 20%.
The present invention makes it possible to obtain a radiation-sensitive photographic product which has improved sensitivity and granularity.
