Silver halide color photographic lightsensitive material |
摘要 |
A silver halide color photographic lightsensitive material comprising a compound represented by general formula (I):wherein COUP represents a coupler residue capable of coupling with a developing agent in an oxidized form, E represents an electrophilic moiety, A represents a single bond or a divalent connecting group which can release B while forming a 4 to 8-membered ring through an intramolecular nucleophilic substitution reaction between the electrophilic moiety E and a nitrogen atom of a coupling product that is obtained by the reaction of COUP with the developing agent in an oxidized form, wherein the nitrogen atom originates from the developing agent and directly binds to a coupling position of COUP, provided that A may be bound to COUP at the coupling position or position other than the coupling position of COUP, and B represents a photographically inert group.
