PROBLEM TO BE SOLVED: To provide an ink for inkjet recording, which is environmentally friendly, has high defoaming property and improves image qualities.SOLUTION: The ink for inkjet recording comprises water, a water-soluble organic solvent, a colorant, a compound having a group expressed by structural formula (1):CF-CHCH-, and a compound expressed by general formula (1):HO-RRC-[CH]-CRR-OH. In general formula (1), Rand Rare each independently selected from alkyl groups having 3 to 6 carbon atoms; Rand Reach independently represent an alkyl group having 1 to 2 carbon atoms; and n represents an integer of 1 to 6. 【課題】環境負荷が少なく、高い消泡性を有し、かつ画像品質が向上するインクジェット記録用インクの提供。【解決手段】水、水溶性有機溶剤、着色剤、下記構造式（１）で表される基を有する化合物、及び下記一般式（１）で表される化合物を含有するインクジェット記録用インクである。Ｃ６Ｆ１３−ＣＨ２ＣＨ２−・・・構造式（１）ＨＯ−Ｒ１Ｒ３Ｃ−[ＣＨ２]ｎ−ＣＲ２Ｒ４−ＯＨ・・・一般式（１）ただし、前記一般式（１）中、Ｒ１及びＲ２は、それぞれ独立に炭素数３〜６のアルキル基から選択され、Ｒ３及びＲ４は、それぞれ独立に、炭素数１〜２のアルキル基であり、ｎは、１〜６の整数である。【選択図】なし
