An object of the present invention is to provide an aqueous ink for inkjet recording, ensuring that even after storage for a long period of time or exposure to a high temperature, the ejection accuracy is excellent and generation of density unevenness and streak unevenness can be suppressed. An aqueous ink for inkjet recording, comprising a vinyl polymer particle containing A and B and a water-soluble solvent:
A: an azo pigment having a specific structure, its tautomer, or a salt or hydrate thereof;
B: a vinyl polymer containing (a) a hydrophobic structural unit having an aromatic ring bonded to the polymer main chain through a linking group and (b) a hydrophilic structural unit. |
