[PROBLEMS] To provide a colorant suitable especially for inks, which has a satisfactory hue and can form an image having high fastness under various use conditions or environmental conditions. [MEANS FOR SOLVING PROBLEMS] The colorant is represented by the following general formula (I).(X) In the formula, G represents a heterocyclic group and n is an integer of 1 to 3. When n is 1, then R, X, Y, Z, Q, and G each represents a monovalent group; when n is 2, then R, X, Y, Z, Q, and G each represents a mono- or divalent substituent, provided that at least one of these represents a divalent substituent; and when n is 3, then R, X, Y, Z, Q, and G each represents a mono-, di-, or trivalent substituent, provided that at least two of these each represents a divalent substituent or at least one of these represents a trivalent substituent. |
