摘要： The present invention provides a pigment dispersion and a method of producing the pigment dispersion. The pigment dispersion includes: water; a pigment; a pigment dispersing polymer; and a rosin acid that includes at least one selected from the group consisting of abietic acid, salts of abietic acid, dihydroabietic acid and salts of dihydroabietic acid, and a total content of abietic acid, salts of abietic acid, dihydroabietic acid and salts of dihydroabietic acid is 50% by mass or higher with respect to a total mass of the rosin acid contained in the pigment dispersion. The pigment dispersion is excellent in terms of dispersibility, storage stability after dispersion, and jettability when used for an inkjet recording ink.

摘要： A pigment composition including at least one pigment selected from the group consisting of a perinone-based pigment and a perylene-based pigment, water, a resin having a constitutional unit represented by Formula 1, and at least one compound selected from the group consisting of a phthalimide compound having a carboxyalkyl group and a naphthalimide compound having a carboxyalkyl group; a method for producing thereof; and an aqueous ink composition using the pigment composition. In Formula 1, R1 represents a hydrogen atom or a methyl group, L2 represents —C(═O)O—, —OC(═O)—, or —C(═O)NR2— and R2 represents a hydrogen atom or an alkyl group having 1 to 6 carbon atoms, and R3 represents an alkyl group having 6 or more carbon atoms.

摘要： Provided are a method for producing an aqueous inkjet pigment dispersion, including producing a mixed liquid of water, a pigment, a pigment dispersing polymer, and rosin acid in an amount of from 3% by mass to 30% by mass relative to the total mass of the pigment, and reducing the amount of rosin acid included in the produced mixed liquid, to less than 3.0% by mass relative to the total mass of the pigment; an aqueous inkjet pigment dispersion; and an aqueous inkjet ink.
