Zusammenfassung:	A new yellow pigment excellent in both brightness and coloring power is provided. It has been found that dimerization of a specific quinophthalone skeleton gives more selective absorption and transmittance. Furthermore, the dimerization method was also studied, and it has been found that excessive reddish tone can be suppressed by cleaving the conjugate using a methylene chain as a spacer instead of simply employing a direct bond. In addition, dispersibility has been improved by polyhalogenation and introduction of an imide structure. Furthermore, a coloring agent containing the quinophthalone compound and a coloring composition containing the coloring agent are provided.
