Silver halide photographic light-sensitive material, photographic emulsion, and mercapto group-containing polymer compound used for them

摘要

Disclosed is a silver halide photographic light-sensitive material, which has at least one polymer compound having a nitrogen-containing aromatic ring having a mercapto group represented by the formula Z-SH wherein Z represents a nitrogen-containing aromatic ring as a partial structure. This silver halide photographic light-sensitive material can stably contain silver halide grains of a high aspect ratio showing high sensitivity and superior planarity, shows superior pressure resistance and can be stably prepared.
