Provided is a method for producing an aqueous pigment dispersion for inkjet recording in which a small particle size pigment is stably dispersed and held even during long term storage. Moreover, the manufacturing method of the aqueous pigment dispersion liquid for inkjet recording with short time required for manufacture of dispersion time etc. and high manufacturing efficiency is provided. The method for producing an aqueous pigment dispersion for inkjet recording includes (1) a 50-90 mass% styrene monomer unit, at least one unit selected from an acrylic acid monomer unit and a methacrylic acid monomer unit, and an acid value of 50-300. The first step of kneading a styrene acrylic resin having a (2) pigment, (3) wetting agent, and (4) a basic compound to produce a solid colored kneaded product, and the solid colored kneaded product Or a second step of dispersing in an aqueous medium consisting of water and a humectant. |
