PROBLEM TO BE SOLVED: To provide an aqueous inkjet ink composition excellent in dot expanding property, uniformity in a solid image, and storage stability, even when the ink composition is printed on a non-absorptive medium.SOLUTION: The aqueous inkjet ink composition comprises a pigment, an alkali-soluble resin, a basic compound, a water-soluble organic solvent, a surfactant (A), and a surfactant (B). The surfactant (A) is an acetylene diol surfactant having an HLB of 4 to 9, and is included by 0.1 to 10 mass% in the aqueous inkjet ink composition. The surfactant (B) is an acetylene diol surfactant having an HLB of 13 to 16, and is included by 0.1 to 10 mass% in the aqueous inkjet ink composition. |
