Abstract: An aqueous ink jet ink contains a pigment aqueous dispersion, water, and a water-soluble organic solvent. The pigment aqueous dispersion contains a pigment dispersed in a polyurethane resin obtained by reaction of an active hydrogen atom-containing component and an organic polyisocyanate component. The active hydrogen atom-containing component contains a quaternary ammonium compound. The organic polyisocyanate component contains one or more selected from the group consisting of a linear or branched aliphatic polyisocyanate, an alicyclic polyisocyanate, and an aromatic polyisocyanate. The weight rate of the quaternary ammonium compound is 12 wt % or more based on the total weight of the active hydrogen atom-containing component and the organic polyisocyanate component.
