Abstract:
A silver halide photographic light-sensitive material comprising at least a light-sensitive silver halide emulsion layer applied on a support, wherein said emulsion layer or another hydrophilic colloidal layer comprises at least one kind of compounds selected from a group consisting of a quaternary nitrogen or phosphorus salt compound, having 20 or more of total recurring units consisting of an ethyleneoxy group and/or a propyleneoxy group in a molecule; a quaternary salt compound represented by the following formula (A); and a quaternary salt compound represented by the following formula (B): wherein Q represents a nitrogen atom or a phosphorus atom, R1, R2 and R3 each independently represent an alkyl group, an aryl group, an alkenyl group, an alkynyl group, or a heterocyclic group, L1 represents an alkylene group, Y represents â€”C (&boxH;O) or â€”SO2â€”, L2 represents a divalent connecting group having at least one hydrophilic group, Xnâˆ’ represents an n-valent counter anion, and n represents an integer of 1 to 3, provided that Xnâˆ’ can be omitted when another anionic group exists in a molecule and forms an intramolecular salt with P+ or a quaternary nitrogen atom, wherein A represents an organic moiety necessary to complete a nitrogen-containing aromatic heterocyclic ring, provided that the nitrogen-containing aromatic heterocyclic ring formed by A may have a substituent, but the substituent having thereon a primary hydroxyl group is excluded, L2 represents a divalent connecting group having at least one hydrophilic group that divides L2 into parts, and L1, Y and Xnâˆ’ each have the same meanings as those of the formula (A).
