Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a color filter coloring composition capable of producing a color filter having high contrast, high transmittance, and high heat resistance.SOLUTION: A color filter coloring composition contains at least silica particles (A), a diketopyrrolopyrrole pigment (B) represented by the specified formula, an organic solvent (C), a dispersant (D), and an alkali-soluble resin (E), where each of the silica particles (A) contains an acrylic functional group on a surface thereof, and a mass ratio [silica particles (A)/diketopyrrolopyrrole pigment (B)] of the silica particles (A) and the diketopyrrolopyrrole pigment (B) is 1/100 to 30/100. 【課題】高コントラスト、高透過率、及び、高耐熱性を有するカラーフィルターを得ることができるカラーフィルター用着色組成物を提供する。【解決手段】少なくともシリカ粒子（Ａ）、特定の式で表されるジケトピロロピロール系顔料（Ｂ）、有機溶媒（Ｃ）、分散剤（Ｄ）及びアルカリ可溶性樹脂（Ｅ）を含有するカラーフィルター用着色組成物であって、前記シリカ粒子（Ａ）は、表面にアクリル官能基を有しており、前記シリカ粒子（Ａ）と前記ジケトピロロピロール系顔料（Ｂ）との質量比［シリカ粒子（Ａ）／ジケトピロロピロール系顔料（Ｂ）］が１／１００〜３０／１００であることを特徴とするカラーフィルター用着色組成物。【選択図】なし
