Abstract: 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.

Abstract: Provided are a pigment dispersion and an aqueous inkjet-recording ink which employs said pigment dispersion. The pigment dispersion makes it possible to obtain a uniform printed image wherein lines and irregularities are suppressed without the particle size of the pigment dispersion changing even after long-term storage or exposure to high temperatures, and also makes it possible to produce an aqueous ink for inkjet recording which has excellent light fastness. A pigment dispersion of vinyl polymer particles contains the following components A and B. A: an azo pigment represented by general formula (1), a tautomer thereof, salts thereof, hydrates thereof, or solvates thereof; and B: a vinyl polymer including (a) a structural unit having a non-aromatic cycloaliphatic group bonded to a polymer main chain through a linking group, and (b) a structural unit having a hydrophilic group. (1) (In general formula (1), Q represents a non-metallic atom group needed to form a 5 to 7-membered heterocycle with a carbon atom, W represents an alkoxy group, an amino group, an alkyl group, or an aryl group, X

Abstract: Provided is a water-based ink for inkjet recording that offers excellent discharge stability and that prevents uneven density and stitching even when stored over a long period of time or exposed to high temperatures. The water-based ink for inkjet recording contains vinyl polymer particles that contain A and B and a water-soluble solvent. A: An azo pigment with a specific structure, a tautomer thereof, or a salt or a hydrate thereof. B: A vinyl polymer containing a hydrophobic structural unit (a) having an aromatic ring joined to a polymer main chain via a linking group, and a hydrophilic structural unit (b).
