PROBLEM TO BE SOLVED: To provide an aqueous inkjet ink using titanium oxide as a pigment, which has excellent printability and discharge stability on a substrate with low absorption and has excellent physical properties of an ink such as storage stability, settling property, and concealing property.SOLUTION: The aqueous inkjet ink comprises at least water, titanium oxide, a pigment dispersant, and an organic solvent. The titanium oxide is a pigment having a surface treated with an organic compound, and a base amount on a surface of the titanium oxide pigment is 28 μmol/g or more. The pigment dispersant is an acidic dispersant having an acid value of 5 mgKOH/g or more and 150 mgKOH/g or less. The organic solvent comprises at least one organic solvent having a boiling point of 200°C or higher and 265°C or lower and a surface tension of 20 mN/m or more and 30 mN/m or less. |
