Abstract
According to one embodiment, an aqueous inkjet ink includes a dispersion medium that contains water and a water-soluble polyhydric alcohol having a weight average molecular weight of 400 or more, and a pigment. The pigment accounts for less than 5 mass % of the total amount of the aqueous inkjet ink. The aqueous inkjet ink has viscosities (mPa·s) measured using a cone-plate type viscometer at 20 rpm and satisfying the following relationships:≧1.5≧10 mPa·s3 mPa·s≦≦15 mPa·s,where Vis the viscosity at 30° C., and Vthe viscosity at 45° C.
