description A method of producing an aqueous dispersion of a pigment, and the aqueous dispersion of the pigment and the uses of the aqueous dispersion of the pigment. In the present method, an inorganic pigment is dispersed in water, in the presence of a dispersing agent. According to the present invention, the inorganic pigment comprises cationic calcium carbonate, especially precipitated calcium carbonate, which is dispersed using a cationic biopolymer, such as starch, in order to prepare an aqueous dispersion, the solids content of which is approximately 30-75% by weight. The dispersion generated can be used, among others, as pigment or filler for ink-jet paper.
