<p>A metal complex dye having a structure defined by general formula (1) and having either 1 or 2 acid groups. [In general formula (1), A and C have a structure represented by general formula (2), and can be the same as or different to one another. B represents a linking group, and n represents an integer not less than 1. The bond between A and B and the bond between B and C can each be at least bivalent. Additionally, a double bond may be included so as to maintain the resonance structure of the compound. In general formula (2), R1-R8 each independently represents a hydrogen atom, a substituent group, or the bond with B in general formula (1). Among R1-R8, those components which are bonded in the same pyrrole ring can be bonded directly or via another base, and have a cyclic structure. X represents a carbon atom or a nitrogen atom. M represents two hydrogen atoms, two metal atoms or metal oxides, or, one metal atom or metal oxide.] FORMULA: AA General formula (1) BB General formula (2)</p> |
