摘要：
An object is to provide an aqueous inkjet ink composition demonstrating excellent drying property, rub fastness, discharge stability, and storage stability even when printed on non-absorbent media. Provided is an aqueous inkjet ink composition containing a pigment, alkali-soluble resin, wax emulsion, basic compound, aqueous medium, and surface active agent, which aqueous inkjet ink composition is characterized in that the average grain size of the wax emulsion is 150 to 200 nm, the solid content of the wax emulsion is 0.5 to 4 percent by mass in the aqueous inkjet ink composition, and the surface active agent is acetylene diol surface active agent.
