摘要:
An aqueous ink for inkjet recording is provided. The aqueous ink ensures that the ejection accuracy in inkjet recording is excellent and helps suppress generation of density unevenness and streak unevenness, even after storage for a long period of time or exposure to high temperatures. The aqueous ink for inkjet recording contains vinyl polymer particles containing components A and B and a water-soluble solvent. Component A is an azo pigment having a specific structure, its tautomer, or a salt or hydrate thereof; and Component B is 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.
