The present invention addresses the problem of providing an aqueous inkjet ink composition for printing on a non-absorbent base material, the aqueous inkjet ink composition having excellent dot extendability, solid uniformity, and storage stability even when printing is performed on a non-absorbent medium. In order to address this problem, provided is an aqueous inkjet ink composition for printing on a non-absorbent base material, the aqueous inkjet ink composition containing: a pigment coated with 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-based compound represented by formula (1), and the content of the surfactant A is 0.1-1 mass% of the aqueous inkjet ink composition. The surfactant B is a compound having an HLB value of 4-9 and being obtained by adding ethylene oxide to an acetylene diol-based compound, and the content of the surfactant B is 0.4-2.5 mass% of the aqueous inkjet ink composition. The static surface tension of the ink composition is 27-32 mN/m. |
