Abstract:
The present invention provides a pigment dispersion excellent in dispersibility. Furthermore, the present invention provides a color filter yellow resist composition and an ink composition, which include the pigment dispersion. A pigment dispersion containing at least a compound represented by General formula (1) and a yellow pigment represented by General formula (2) in a dispersion medium and a method for manufacturing the same are provided. Furthermore, a color filter yellow resist composition and an ink composition are provided, wherein images can be displayed with high spectral characteristics and high display contrast because the brightness is high and the hue of yellow is excellent.
