摘要
(WO2019/092036) The present invention relates to a water-insoluble polymer in the form of an aqueous polymer dispersion, which can be used as a dispersion agent for pigments in non-aqueous colourant preparations, wherein the pigments to be dispersed are additivized with the aqueous polymer dispersion during production thereof, thus producing an additive-enhanced, easily dispersible pigment for non-aqueous colourant preparations.
