Abstract:
A silver halide photographic light-sensitive material comprising a support having thereon at least one layer comprising at least one compound represented by the following general formula (1): ##STR37## wherein, R.sub.1 to R.sub.4 represent a hydrogen atom or a substituent, A represents a hydroxyl group or a substituted amino group, X represents a first connecting group selected from --CO--, --SO--, --SO.sub.2 -- and ##STR38## (Q represents a monovalent group), Y.sub.k and Z.sub.k represent a nitrogen atom or a group represented by --CR.sub.5 .dbd. (R.sub.5 represents a hydrogen atom or substituent), k represents an integer of 0 or more, D represents a proton dissociating group or a group which can be a cation, wherein said proton dissociating group contains a proton dissociating atom selected from the group consisting of an oxygen atom, a sulfur atom, a selenium atom, a nitrogen atom carrying a substituent of an electron attracting group, and a carbon atom carrying a substituent of an electron attracting group, wherein Y.sub.k, Z.sub.k or D contains a ballast group having 8 to 80 carbon atoms, and wherein D forms a dye by breaking of a N--X bond and removal of a substituent bonded to a coupling part of a coupler caused by transfer of an electron from D after a coupling reaction of the coupler and with an oxidized compound produced by a redox reaction of the compound represented by the general formula (1) with silver halide, R.sub.1 and R.sub.2 may be linked to each other to form a ring, R.sub.3 and R.sub.4 may be linked to each other to form a ring, and at least two kinds of atoms or substituents selected from Y.sub.k, Z.sub.k and D may be linked IQ each other to form a ring.
