Abstract:
1. A method for producing a dispersion composition which comprises (a) a step of dispersing a particulate material using a self-dispersing graft copolymer having a particle diameter of 0.01-1 μm in an organic solvent in which the graft copolymer is soluble and (b) a step of pouring an organic solvent in which the graft copolymer is insoluble into the dispersion obtained in the step (a) or pouring the dispersion obtained in the step (a) into an organic solvent in which the graft copolymer is insoluble, followed by mixing to precipitate the graft copolymer and to adsorb the graft copolymer to the particulate material.
