PROBLEM TO BE SOLVED: To provide an ink enabling the recording of images having high optical density while the irregular ejection is suppressed.SOLUTION: An ink for ink jet contains a pigment and a resin for dispersing the pigment. The pigment has inclusion of a compound in which at least two structures represented by general formula (1) are bonded by a glycoside bond. (Rto Rare each independently a hydrogen atom, hydroxy group, amino group or the like, provided that at least one of Rand Ris a hydroxy group.)SELECTED DRAWING: None 【課題】吐出よれを抑制しながら、光学濃度が高い画像を記録することが可能なインクを提供する。【解決手段】顔料、及び顔料を分散するための樹脂を含有するインクジェット用のインクである。顔料が、一般式（１）（Ｒ1乃至Ｒ6は、それぞれ独立に水素原子、ヒドロキシ基、アミノ基などであるとともに、Ｒ1及びＲ2の少なくとも一方はヒドロキシ基である）で表される少なくとも２つの構造がグリコシド結合した化合物を内包する。【選択図】なし
