Abstract:
To provide an aqueous ink that can suppress the dissolution of silicon or a silicon compound contained in a recording head, can be stably, continuously ejected for a long time, and enables the recording of an image having excellent glossiness. An aqueous ink for ink jet includes a pigment, a resin dispersant for dispersing the pigment, an alkanolamine and a urethane resin. The pigment is a solid solution containing C.I. Pigment Red 122 and C.I. Pigment Violet 19, and the proportion (% by mass) of the C.I. Pigment Red 122 is 10% by mass or more to 90% by mass or less based on the total mass of the solid solution.
