<P>PROBLEM TO BE SOLVED: To provide: a colored composition for color filter which has excellent dispersibility, is superior in flowability and stable, and also has excellent developability; and a high-quality color filter that has a filter segment with a high contrast ratio or a black matrix with high optical density, using the colored composition for color filter. <P>SOLUTION: A colored composition for color filter contains a colorant, a resin type dispersant, and a solvent, in which the colorant contains a pigment with an average primary particle diameter being 20-50 nm and an aspect ratio of pigment particles being 1:1-1:3.5, and the resin type dispersant contains an acrylic block copolymer which is A-B block copolymer or B-A-B block copolymer comprising A block having solvent affinity and B block having a nitrogen atom-containing functional group and of which amine value is 10 mgKOH/g or more and 99 mgKOH/g or less in terms of effective solid content. <P>COPYRIGHT: (C)2013,JPO&INPIT |
