Abstract (en)
[origin: EP0628861A1] A silver halide light-sensitive material containing a hydrazine compound represented by formula (I): <CHEM> wherein L<1> represents a single bond, -O-, -S-, -NR<6>-, -CO-, SO2-, -P(O)(G<2>R<6>)- or a combination thereof; L<2> represents -SO2NR<6>-, -NR<6>SO2NR<6>-, -CONR<6>-, -NR<6>CONR<6>- or -G<2>P(O)(G<2>R<6>)NR<6>-; G<1> represents -CO-, -SO2-, -SO-, -COCO-, a thiocarbonyl group, an iminomethylene group or -P(O)(G<2>R<6>)-; G<2> represents a single bond, -O- or -NR<6>-; R<1> represents an aliphatic group or an aromatic group; R<2>, R<3>, and R<4> each represent a divalent aliphatic group or a divalent aromatic group; R<5> represents a hydrogen atom, an aliphatic group, an aromatic group, an alkoxy group, an aryloxy group or an amino group; R<6> represents a hydrogen atom, an aliphatic group or an aromatic group; m represents 0 or 1; and X<-> represents a counter anion or a counter anion moiety of an intramolecular salt, as a nucleating agent. The light-sensitive material exhibits high processing stability even in rapid processing to provide a ultrahigh contrast negative image for photomechanical processing.
