Hydrazide compound and silver halide photographic photosensitive material comprising the same

摘要

A hydrazide compound represented by the following formula (I), and a silver halide photographic photonsensitive material comprising the hydrazide compound:A-(B)b(I)wherein A represents a heterocyclic group, a condensed polycyclic aromatic group or a group formed by connecting at least two aromatic groups to each other, B represents a group represented by the following formula (I-B) or (II-B), and b represents an integer from 2 to 6;-L1-Ar1-NHNH-G1-R1(I-B)-L3-Ar3-L2-Ar2-NHNH -G2-R2(II-B)wherein each of G1 and G2 represents a carbonyl group, an oxalyl group, a sulfonyl group or a phosphoryl group; each of R1 and R2 represents a hydrogen atom or a blocking group; each of Ar1, Ar2 and Ar3 represents an aromatic group or an aromatic heterocyclic group; and each of L1, L2 and L3 represents a linkage group.
