Abstract
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.
Claims9
A mercapto group-containing polymer compound, which is represented by the following formula (2):
- Y1—[—X—]—Y2 Formula (2)
- wherein X represents a group derived from a homopolymer or copolymer of monomers having an ethylenic unsaturated bond;
- and
- Y1 and Y2 represent an end group of X, and at least one of them represents HS-Z-L1-, wherein Z represents a nitrogen-containing aromatic ring and L1 represents a divalent bridging group or a single bond.
