Silver halide photographic light-sensitive materials
摘要:
A silver halide photographic light-sensitive material is described comprising a layer containing a coupler compound represented by formula (I)A--B (I)wherein A represents a residue of a compound capable of undergoing a coupling reaction with an oxidation product of an aromatic primary amine developing agent, by the removal of one hydrogen atom from the active position of said compound, and B represents a group which is released by the coupling reaction and exhibits a development accelerating function.
