Abstract:
An aqueous ink jet ink composition contains a pigment, propylene glycol, and water, in which the aqueous ink jet ink composition has the viscosity of 3.0 mm2/s or more and 10.0 mm2/s or less at 20° C., the aqueous ink jet ink composition has the pH of 7 or more, the content of the pigment is 5.5% by mass or more and 9% by mass or less based on the total amount of the aqueous ink jet ink composition, and the content of the propylene glycol is 8 parts by mass or more and 100 parts by mass or less based on 100 parts by mass of the pigment.
