Zusammenfassung:	PROBLEM TO BE SOLVED: To provide aqueous inkjet ink having all of good quick drying properties, water resistance and image quality even in comparatively low temperature drying, when used for printing onto a polyvinyl chloride base material.SOLUTION: Inkjet ink contains at least water (A), a coloring material (B), a water-soluble organic solvent component (C), resin fine particles (D) and a surface active agent (E), where the ink contains 8 mass% or more of 3-methoxy-1-butanol as the water-soluble organic solvent component (C) in the ink, a content of the surface active agent (E) in the ink is 2 mass% or less, and a static surface tension at 25°C determined by Wilhelmy method is 27.0 mN/m or less.SELECTED DRAWING: None 【課題】ポリ塩化ビニル基材への印刷に用いた場合に、比較的低温乾燥でも、速乾性、耐水性、および画像品質のすべてが良好な水性インクジェットインクを提供する。【解決手段】少なくとも水（Ａ）、色材（Ｂ）、水溶性有機溶剤成分（Ｃ）、樹脂微粒子（Ｄ）、および界面活性剤（Ｅ）を含有するインクジェットインクであって、前記インクは、前記水溶性有機溶剤成分（Ｃ）として、３−メトキシ−１−ブタノールを前記インク中８質量％以上含有し、前記界面活性剤（Ｅ）のインク中の含有量が２質量％以下であり、２５℃においてＷｉｌｈｅｌｍｙ法により求まる静的表面張力が２７．０ｍＮ／ｍ以下であることを特徴とする、インクジェットインクとする。【選択図】なし
