PROBLEM TO BE SOLVED: To provide an aqueous ink good in dispersion stability of a pigment and capable of recording images excellent in storage stability and color development.SOLUTION: There is provided an aqueous ink for inkjet containing a pigment and a resin dispersant. The resin dispersant has a unit (X) derived from α-olefin polymer containing at least one of an ethylene unit and a propylene unit in a constitutional unit, a unit (A) derived from (meth)acrylic acid and a unit (B) derived from (meth)acrylate and has the content of the unit (A) of 0.60 to 1.00 times or less and the content of the unit (B) of 0.60 to 1.00 times as ratios to 100 pts.mass of the unit (X), the content of the unit (A), A (mass%) with mass ratio to the content of the unit (B), B (mass%) of 1.0 to 1.7 times based on the total mass of the resin dispersant. |
