Silver halide photographic light-sensitive material and process for producing silver halide photographic emulsion

摘要

A silver halide photographic light-sensitive material is described comprising a support having thereon at least one light-sensitive silver halide emulsion layer, said silver halide emulsion layer containing a rhodium salt in an amount sufficient to increase a contrast thereof, and said silver halide emulsion layer or a layer adjacent thereto containing a compound represented by the following formula (I) or (II), and a process for producing a silver halide photographic emulsion containing rhodium salts is also described which comprises adding a rhodium salt into a silver halide photographic emulsion in an amount sufficient to increase a contrast before the conclusion of first ripening and adding a compound represented by the following formula (I) or (II) into the resulting emulsion after washing to remove useless salts (I) (II) wherein R1 represents hydrogen or a substituted or unsubstituted alkyl group. The silver halide photographic light-sensitive material and a silver halide photographic emulsion each is capable of providing high contrast images and stabilized photographic properties; particularly, gradation properties remain stable during storage.
