PROBLEM TO BE SOLVED: To provide a method for producing a water-based ink for ink-jet recording, which has little dependence on the viscosity and viscoelasticity of a dispersion and the type of a dispersing machine, and can easily manage the dispersion process of the ink. SOLUTION: The method for producing an aqueous ink for ink-jet recording of the present invention is characterized in that when a pigment dispersion obtained by preliminarily dispersing at least a pigment and a polymer dispersant in an aqueous liquid medium is dispersed by a sand mill, The integrated power per unit weight is 0.1 to 10 kWh / kg. |
