摘要:
An object is to overcome the drawbacks of conventional blue phthalocyanine pigments upon the formation of images, and to develop a blue pigment that can satisfactorily exhibit a greenish blue color high in chroma and excellent in colorfulness, brightness, dispersibility, hue, tinting power and the like and that is applicable to various image recording methods. The object can be achieved by a greenish blue pigment, which exhibits a greenish blue hue of high chroma and contains a pigment represented by the following formula (I): wherein the number, m, of substituent phthalimidomethyl group(s) is in a range of 1.0≦m≦5.0, and the number, n, of a substituent sulfonic group R1 is in a range of 0.05≦n≦1.0.
