摘要:
1. A 1-naphthol compound represented by formula (I) below: wherein A represents the moiety of a compound having an acidic proton the pKa of a corresponding protonated form (AH) of which is 0 to 14, R1 represents an aliphatic group, aryl group, or heterocyclic group, R2 represents a substituent, n represents an integer of 0 to 5, X represents a hydrogen atom, halogen atom, R11—, R11O—, R11S—, R11OCOO—, R12COO—, R12(R13)NCOO—, R12CON(R13)—, —NO, —NO2, or —N═N—R11, wherein R11 represents an aliphatic group, aryl group, or heterocyclic group, and each of R12 and R13 independently represents a hydrogen atom, aliphatic group, aryl group, or heterocyclic group, and Y represents an oxygen atom or sulfur atom.
摘要:
A silver halide color photographic material contains a coupler capable of releasing a photographically useful group or its precursor by a coupling reaction between the coupler and a developing agent in an oxidized form, wherein the coupler releases the photographically useful group or its precursor by an intramolecular nucleophilic substitution reaction using the nitrogen atom that directly bonds to a coupling position of a product obtained by the coupling reaction and that originates from the developing agent.
