PROBLEM TO BE SOLVED: To provide an aqueous pigment composition and a printing agent which have excellent storage stability and are reduced in bleeding.SOLUTION: There are provided: an aqueous pigment composition which comprises a pigment, a water-soluble solvent and/or water, a polyester polyol (a1-1) obtained by reacting a polycarboxylic acid and a polyol as a polyol (a1), an urethane resin obtained by reacting a polyol having a hydrophilic group which is an anionic group, a cationic group, a polyoxyethylene group or a polyoxyethylene-polyoxypropylene group with a polyisocyanate (a2), at least one additive selected from a cellulose derivative and a macromolecular polysaccharide; a printing agent containing the aqueous pigment composition; and a method for printing the aqueous pigment composition on a fabric. 【課題】 保存安定性に優れ、にじみが低減された水性顔料組成物及び捺染剤を提供する。【解決手段】 顔料と、水溶性溶媒及び／または水と、ポリオール（ａ１）としてポリカルボン酸とポリオールを反応させて得られるポリエステルポリオール（ａ１−１）と、アニオン性基、カチオン性基、ポリオキシエチレン基またはポリオキシエチレン−ポリオキシプロピレン基である親水性基を有するポリオールと、ポリイソシアネート（ａ２）とを反応させて得られるウレタン樹脂と、セルロース誘導体及び高分子多糖類から選ばれる少なくとも１種の添加剤を含有する水性顔料組成物、前記水性顔料組成物を含む捺染剤、及び前記水性顔料組成物を布帛に印捺する捺染方法。【選択図】 なし
