摘要：
According to one embodiment, an aqueous inkjet ink includes a color material, water in an amount of from 50-70% by mass of the total amount of the ink, and a water-soluble organic solvent in an amount of from 29-49% by mass of the total amount. The water-soluble organic solvent contains a compound represented by the following general formula 1, and the compound represented by the following general formula 1 accounts for 10-35% by mass of the total amount of the ink. 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, R1 and R2 each independently represent an alkyl group having 1 to 4 carbon atoms, and m and n each represent an integer satisfying the relation: 2≦m+n≦6.
