PHENANTHROLINE COMPOUND AND COLORANT

PROBLEM TO BE SOLVED: To provide a phenanthroline compound having a new skeleton available as a yellow pigment. SOLUTION: The phenanthroline compound is represented by the general formula in the figure. (In the general formula (1), R1 and R2 each independently represent a hydrogen atom, or an optionally substituted alkyl group, aryl group or indandione group, provided that at least one of R1 and R2 is the optionally substituted indandione group; and R3 and R4 each independently represent a hydrogen atom or a phenyl group.)
