A silver halide light-sensitive material containing a compound represented by formula (I): <CHEM> wherein L<1> represents -O-, -S-, -SO-, -SO2-, -N(R<4>)-, -CONR<4>-, -NR<4>CO-, -OCONR<4>-, -NR<4>CONR<4>-, -SO2NR<4>-, -NR<4>SO2- or -NR<4>SO2NR<4>-, each of which is bonded to the pyridine ring at the right hand side thereof; L<2>, L<3>, and L<4> each represent a divalent aliphatic group or a divalent aromatic group; G represents -CO-, -SO2-, -SO-, -COCO-, a thiocarbonyl group, an iminomethylene group or -P(O)(G<1>R<4>)-; G<1> represents a single bond, -O- or -NR<4>-; R<1> represents an aliphatic group or an aromatic group; R<2> represents a monovalent substituent; n<1>represents 0 or an integer of from 1 to 4; R<3> represents a hydrogen atom, an aliphatic group, an aromatic group, an alkoxy group, an aryloxy group or an amino group; R<4> represents a hydrogen atom, an aliphatic group or an aromatic group; R<5> represents a monovalent group; m represents 0 or an integer of from 1 to 4; n<2> represents 0 or an integer of from 1 to 5; and X<-> represents a counter anion or a counter anion moiety in an intramolecular salt; two or more R<2>'s, R<4>'s or R<5>'s, if any, may be the same or different. The light-sensitive material exhibits high processing stability even in rapid processing and provides a high contrast image even when developed with a developing solution at a low pH. |
