The purpose of the present invention is to provide a dye compound exhibiting high color intensity and excellent light resistance. A dye compound characterized by being represented by general formula (1). (In general formula (1), R 1 and R 2 each independently represent an alkyl group or an acyl group, or R 1 and R 2 may bind and form a cyclic organic functional group containing a nitrogen atom, to which R 1 and R 2 bind, as a hetero atom; R 3 and R 4 each independently represent an alkyl group; R 5 and R 6 each independently represent an alkyl group or an alkoxy group; R 7 represents a hydrogen atom, an alkyl group, or an alkoxy group; and R s represents an alkyl group.) |
