Zusammenfassung:	PROBLEM TO BE SOLVED: To provide filter segments with a high contrast ratio produced using a color filter coloring composition which is superior in terms of a contrast ratio (CR value), dispersion stability, and chemical resistance, and a high-quality color filter.SOLUTION: A color filter coloring composition which solves the above mentioned problem contains: a pigment (A); a binder resin (B); a resin dispersant (C); and a solvent (D). The binder resin (B) contains a resin (B1) which is obtained by having (b4) react with a copolymer obtained by copolymerizing (b1), (b2), and (b3), and contains a repeating unit derived from (b3) and a repeating unit derived from (b3) and (b4) in an amount of 75-95 mol% with respect to a total mole number of all repeating units in the resin. 【課題】本発明は、コントラスト比（ＣＲ値）、分散安定性に優れ、かつ耐薬品性にも優れたカラーフィルタ用着色組成物を用いた、高コントラスト比のフィルタセグメント、高品質のカラーフィルタの提供を目的とする。【解決手段】上記課題は、顔料（Ａ）、バインダー樹脂（Ｂ）、樹脂型分散剤（Ｃ）及び溶剤（Ｄ）を含有するカラーフィルタ用着色組成物において、バインダー樹脂（Ｂ）が、（ｂ１）〜（ｂ３）を共重合させて得られる共重合体に、さらに（ｂ４）を反応させて得られた樹脂であって、かつ（ｂ３）から導かれる繰り返し単位と、（ｂ３）および（ｂ４）から導かれる繰り返し単位とが、樹脂の全繰り返し単位の合計モル数中、７５〜９５モル％である樹脂（Ｂ１）を含むことを特徴とするカラーフィルタ用着色組成物により解決される。【選択図】なし
