ABSTRACT:
A coated pigment highly surface-modified with a substantially water-insoluble organic surface modifier, produced by preparing a mixture of water and a substantially water-insoluble organic surface modifier, pressurizing the mixture, introducing the mixture into a flow path having a diameter-decreased portion and a turning portion to cause a shear force in the mixture of which the flow is accelerated while the mixture is passing the diameter-decreased portion, mutual collision of the mixture of which the flow has been accelerated or collision of the mixture of which the flow has been accelerated against a wall constituting the flow path, thereby obtaining an aqueous dispersion in which the substantially water-insoluble organic surface modifier is homogeneously dispersed in the water, mixing the aqueous dispersion with the pigment to coat the pigment with the substantially water-insoluble organic surface modifier, and isolating the pigment coated with the substantially-water-insoluble organic surface modifier.
