Abstract
A silver halide photographic light-sensitive material is described containing at least one electron-donative, silver halide-adsorptive compound represented by the following general formula (A) or (B), which is not a spectral sensitizing agent for silver halide or a nucleating agent: EQU D--L--X (A) EQU D--X (B) wherein D represents an electron donative atomic group comprising an aromatic ring or hetero ring, which may be unsubstituted or substituted with at least one substituent; L represents a linkage group containing at least one of C, N, S or O; and X represents a group which is adsorptive with a silver halide-adsorptive group containing at least one of C, N, S, O or Se, said N being optionally quarternized.
