Abstract
Disclosed is a silver halide photographic light-sensitive material, which comprises 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.
