【Task】 Dispersing to a submicron region of 1 μm or less with fine media can simultaneously promote the refinement of the yellow pigment whose surface is acidic and the resin coating on the pigment, with high brightness and contrast ratio, and fluidity Of a stable coloring composition for a color filter excellent in color, and a coloring composition for a color filter having good color characteristics and excellent heat resistance, and a color filter, formed using the manufacturing method . [Solution] The problems include a colorant (a) containing a yellow pigment (a1) having a specific surface area of 90 m 2 / g or more by the BET method and an acidic surface, a resin (b), a resin-type dispersant (c), and A coloring composition for a color filter, characterized in that a mill base containing at least one selected from the group consisting of a solvent (d) is finely dispersed by a media type dispersing machine having a media of 0.01 to 0.1 mmφ. It is solved by the manufacturing method. [Selection figure] None |
