Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a colored composition for a color filter to be used in a developing step using a potassium hydroxide developing solution, which shows good linearity of a pattern and leaves little residue, and a color filter excellent in resolution formed by using the above colored composition for a color filter.SOLUTION: The colored composition for a color filter is a colored composition for a color filter to be subjected to potassium hydroxide development, and the composition comprises a colorant (A), a resin type dispersant (B), a binder resin (C), a photopolymerizable monomer (D) and a photopolymerization initiator (E). The photopolymerizable monomer (D) contains a (meth)acryl compound (D1) having 1 to 3 unsaturated bond groups in one molecule and having a weight average molecular weight of 250 to 1000, by 10 mass% to 90 mass% in 100 mass% of the photopolymerizable monomer (D). The resin type dispersant (B) comprises a resin type dispersant having a glass transition temperature (Tg) of 30 to 100°C and an amine value of 50 to 150 mgKOH/g.SELECTED DRAWING: None 【課題】水酸化カリウム現像液を使用した現像工程に用いられるカラーフィルタ用着色組成物であって、パターンの直線性と残渣が良好であり、該カラーフィルタ用着色組成物を用いて形成された、解像度に優れたカラーフィルタの提供。【解決手段】着色剤（Ａ）、樹脂型分散剤（Ｂ）、バインダー樹脂（Ｃ）、光重合性単量体（Ｄ）、および光重合開始剤（Ｅ）を含有するカラーフィルタ用着色組成物において、光重合性単量体（Ｄ）が、不飽和結合基を一分子中に１〜３個有する重量平均分子量２５０〜１０００の（メタ）アクリル化合物（Ｄ１）を、光重合性単量体（Ｄ）１００質量％中、１０質量％〜９０質量％含有し、樹脂型分散剤（Ｂ）が、ガラス転移温度（Ｔｇ）が３０〜１００℃、かつアミン価が５０〜１５０ｍｇＫＯＨ／ｇである樹脂型分散剤を含有することを特徴とする水酸化カリウム現像用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
