摘要： A silver halide photographic light-sensitive material which provides an improved safelight property without adversely affecting the photographic properties of the light-sensitive material. The silver halide photographic light-sensitive material contains at least one compound represented by formula (I): ##STR1## wherein R.sub.1 and R.sub.2 each represent a hydrogen atom or a substitutable group; W represents a nitrogen atom or a carbon atom; Z represents --Y.sub.1 --(R.sub.3)n.sub.2 or R.sub.3 in which R.sub.3 represents a hydrogen atom or a substitutable group; n.sub.0, n.sub.1 and n.sub.2 each represents 0 or 1; h represents 1 or 2; R.sub.1 and R.sub.2 and R.sub.3 may combine with each other to form a hydrocarbon ring or a heterocyclic ring; Y.sub.1 represents --CO--, --CO(.dbd.NR.sub.4)--, --C(.dbd.S)--, --C(.dbd.N.sup.+ R.sub.5 R.sub.6)--, --SO--, --SO.sub.2 --, --C(C.dbd.CR.sub.7 R.sub.8)--,--R.sub.6 C.dbd.N--, or --R.sub.6 C.dbd.CR.sub.9 --in [(R.sub.1).sub.n1 --Y.sub.1 ] when n.sub.1 is 1 and in --Y.sub.1 --(R.sub.3).sub.n2 when n.sub.2 is 1 in which R.sub.4, R.sub.5, R.sub.6, R.sub.7, R.sub.8 and R.sub.9 each represents a hydrogen atom or a substitutable group, Y.sub.1 represents a cyano group or a nitro group in [(R.sub.1).sub.n1 --Y.sub.1 ] when n.sub.1 is 0 and in --Y.sub.1 --(R.sub.3).sub.n2 when n.sub.2 is 0; X represents a divalent linkage group; D represents a photographic dye residue; and M represents an amphoteric group having a cationic group and an anionic group.
