To provide an ink which has excellent color reproducibility, high cleaning power, and low dot height of post-processing fluid on an ink film.SOLUTION: A liquid composition contains a coloring material, an organic solvent, a compound represented by general formula 1 below, a resin, and water. The contact angle of water against a liquid composition film formed by attaching the liquid composition to a non-permeable printing medium is 60 degrees or less. In the formula, n represents an integer of from 4 to 10. Preferably, the liquid composition comprises, as the coloring material, a resin-coated pigment, and comprises, as the organic solvent, a diol having five or more carbon atoms.SELECTED DRAWING: None 【課題】色再現性が優れ、洗浄性が高く、インク膜上の後処理液のドットハイト（ドット高さ）抑制に優れたインクを提供すること。【解決手段】色材、有機溶剤、下記一般式（１）で表される化合物、樹脂、及び、水を含有する組成液であって、前記組成液を非浸透性記録媒体に付着させて形成した組成液膜に対する水の接触角が６０度以下となる組成液。式中、ｎは４～１０の整数を示す。前記組成液は、前記色材として樹脂被覆型顔料を有し、前記有機溶剤として、炭素数が５以上のジオールを有することが好ましい。TIFF2022191157000015.tif30136【選択図】なし
