摘要:
An aqueous inkjet recording ink including pigment particles coated with a water-insoluble resin, water, and a water-soluble organic solvent including at least one hydroxy group, wherein the water-insoluble resin has a salt-forming group and a structural unit which is derived from a methacrylate and has an aromatic ring linked via a linking group to an atom in the main chain of the water-insoluble resin, and the water-insoluble resin satisfies the condition that when the water-insoluble resin, an organic solvent, one equivalent of a neutralizing agent with respect to the salt-forming group, and water are mixed with a total content of the water-insoluble resin and the organic solvent being 35% by mass relative to the total mass of the mixture, an emulsion is formed without precipitation of the water-insoluble resin, and after the emulsion is allowed to stand for three hours, a transparent single phase is formed, or two separate phases are formed and at least an aqueous phase of the two phases is transparent.
