To provide a pigment composition for a color filter which is high in contrast as a coloring composition, has few film defect of a coated film even after long-term storage under temperature fluctuation, and is excellent in characteristics dependence of a pattern to time (long-term PCD) (PCD: Post Coating Delay) from coating to exposure of the composition when it is applied as a coloring curable composition.SOLUTION: There is provided a pigment composition for a color filter which contains a dye derivative of specific structure having an anthraquinone skeleton at a specific mass ratio.SELECTED DRAWING: None 【課題】着色組成物とした時にコントラストが高く、温度変動下で長期保管しても塗膜の膜欠陥が少なく、着色硬化性組成物とした時に組成物の塗布から露光までの時間（長時間引き置き）（ＰＣＤ：Ｐｏｓｔ Ｃｏａｔｉｎｇ Ｄｅｌａｙ）に対するパターンの特性依存性が良好となる、カラーフィルタ用顔料組成物を提供する。【解決手段】顔料に、アントラキノン骨格を有する特定構造の色素誘導体を特定の質量比率で含有するカラーフィルタ用顔料組成物。【選択図】なし
