Abstract
An aqueous inkjet ink composition contains a pigment, an alkali-soluble resin, a polyolefin resin emulsion, a basic compound, an aqueous medium, and a surfactant, wherein the alkali-soluble resin is a copolymer of acrylic acid/lauryl acrylate/styrene; a glass transition temperature of the alkali-soluble resin is 45° C. to 95° C.; an average grain size of the polyolefin resin emulsion is 5 to 300 nm; a solids content of the polyolefin resin emulsion is 0.5 to 5.0 percent by mass in the aqueous inkjet ink composition; and the surfactant contains at least an acetylenediol-based surfactant. The aqueous inkjet ink composition is adapted to offering excellent high-gap discharge stability, antifouling property, adhesion, drying property, abrasion resistance, discharge stability, and preservation stability, even when printed on nonabsorbent media.
