PROBLEM TO BE SOLVED: To provide an ink having excellent flexibility and high glossiness.SOLUTION: There is provided an ink containing water, an organic solvent and a coloring material, the ink contains an urethane resin particle and an acrylic resin particle, difference of total HSP value of the organic solvent with the highest boiling point in the organic solvent and total HSP value of the urethane resin particle is 6.0 [(J/cm)] or less and difference of polar HSP value of the organic solvent with the highest boiling point in the organic solvent and polar HSP value of the urethane resin particle is 5.0 [(J/cm)] or less.SELECTED DRAWING: Figure 1 【課題】優れた定着性と高い光沢を有するインクを提供する。【解決手段】水、有機溶剤及び色材を含有するインクであって、該インクは、ウレタン系樹脂粒子及びアクリル系樹脂粒子を含有し、前記有機溶剤の中で最も沸点が高い有機溶剤のトータルＨＳＰ値と、前記ウレタン系樹脂粒子のトータルＨＳＰ値との差分が６．０［（Ｊ／ｃｍ３）０．５］以下であり、且つ、前記有機溶剤の中で最も沸点が高い有機溶剤の極性ＨＳＰ値と、前記ウレタン系樹脂粒子の極性ＨＳＰ値との差分が５．０［（Ｊ／ｃｍ３）０．５］以下であることを特徴とする。【選択図】図１
