Abstract
There is disclosed a silver halide photographic material, which comprises a compound represented by the following formula (I): ##STR1## wherein R.sub.1 and R.sub.2 each represent a hydrogen atom or a group being capable of substitution; W represents a nitrogen atom or a carbon atom; Z represents --Y.sub.1 --(R.sub.3).sub.n2 or R.sub.3 in which R.sub.3 represents a hydrogen atom or a group being capable of substitution; n.sub.0, n.sub.1, and n.sub.2 each are 0 or 1; h is 1 or 2; R.sub.1, R.sub.2, and R.sub.3 may bond together to form a carbocyclic ring or a heterocyclic ring; when n.sub.1 and n.sub.2 each are 1, Y.sub.1 represents --CO--, --C(.dbd.NR.sub.4)--, --C(.dbd.S)--, --C(.dbd.N.sup.+ R.sub.5 R.sub.6)--, --SO--, --SO.sub.2 --, --C(.dbd.CR.sub.7 R.sub.8)--, --R.sub.6 C.dbd.N--, or --R.sub.6 C.dbd.CR.sub.9 --, in which R.sub.4, R.sub.5, R.sub.6, R.sub.7, R.sub.8, and R.sub.9 each represent a hydrogen atom or a group being capable of substitution; when n.sub.1 and n.sub.2 each are 0, Y.sub.1 represents a cyano group or a nitro group; X represents a divalent linking group bonded to the carbon atom through a heteroatom; Q.sub.1 represents an electron-attractive group; Q.sub.2 represents a group for stabilizing the negative charge that will result from the addition of a nucleophilic agent to the adjacent unsaturated bond; Q.sub.3 represents a divalent linking group; M represents a furan ring or a benzofuran ring; L represents a (m.sub.1 +1)-valent linking group; B represents a group capable of making the compound water-soluble; m.sub.0 is 0 or 1; and m.sub.1 and m.sub.2 each are 1, 2, or 3.
