Abstract:
According to one embodiment, an aqueous inkjet ink includes a pigment in an amount of 2 to 20% by mass of the total amount of the aqueous inkjet ink, and a dispersion medium in which the pigment is dispersed. The dispersion medium contains water in the amount of 53 to 94% by mass, with the remainder of the dispersion medium being a compound represented by the following general formula 1. The water accounts for 50 to 80% by mass of the total amount of the aqueous inkjet ink. In the general formula 1, a, b, and c may be the same or different, each representing an integer of 1 or more, and satisfy the following inequation: 4≦a+b+c≦10.
