Abstract: A process for producing a resin-coated pigment capable of providing an ink and a paint being superior in dispersion stability of a pigment and having rapid drying property, high gloss and density without containing those such as an organic solvent and a salt that cause the lowering of performance of pigment dispersion, characterized in that a pigment is dispersed in an aqueous solution in which an anionic group-containing resin is dissolved in the presence of a basic compound and then, the anionic group-containing resin is precipitated on the surface of the pigment by removing the basic compound in the aqueous solution, using an ion exchange means.

Abstract: The object of the invention is to provide a white ink composition for ink jet textile printing by which even if printing is carried out without discoloring the dye of textile piece, the whiteness degree of a dyed article obtained is high and the dyed article superior in coating film durability and laundering fastness is further obtained without losing the drape of the textile piece. The invention is directed to a white ink composition for ink jet textile printing including a white pigment, a polymer dispersant, an anionic resin emulsion and an aqueous medium, wherein the polymer dispersant is a polymer dispersant (A) obtained by neutralizing a anionic water-soluble resin having a glass transition temperature of 0 to 80° C.
