    • According to one embodiment, an aqueous inkjet ink includes a color material, water in an amount of 50-70% by mass of the total amount of the ink, and a water-soluble organic solvent in an amount of 29-49% by mass of the total amount. The soluble organic solvent contains a compound represented by the following general formula 1 which accounts for 10-36% by mass of the total amount of ink. When the amount of the compound is equal to the amount of the solvent, the total amount of the solvent is the compound. The sum of the amounts of the color material, the water, and the water-soluble organic solvent is 100% by mass or less of the ink. Where, X1, X2, and X3 each independently represent EOn, and X4 represents an CH3CH2— or an (EOn)O—. EOn is represented by the following general formula 2, where n representing an integer of 1-5. CH2—CH2nOH  general formula 2
    • 根据一个实施方案,水性喷墨油墨包括着色材料,水的总量为油墨的50-70质量%,水溶性有机溶剂的量为29-49质量% 的总量。 可溶性有机溶剂含有由以下通式1表示的化合物,其占总量的10-36质量%。 当化合物的量等于溶剂的量时,溶剂的总量为化合物。 着色材料,水和水溶性有机溶剂的量的总和为油墨的100质量%以下。 其中,X 1,X 2和X 3各自独立地表示EO,X 4表示CH 3 CH 2 - 或(EOn)O-。 EOn由以下通式2表示,其中n表示1-5的整数。 通式2
