摘要：The invention relates to a method for improving rheological properties of anaqueous pigment slurry. In the method dispersion agent is added to an aqueous phase ofa slurry comprising pigment particles or to the aqueous phase into which the pigmentparticles are to be added. The dispersion agent comprises styrene acrylate copolymer.The invention also relates to a dispersion agent for a pigment slurry comprising a firstcomponent comprising styrene acrylate copolymer and a second component comprisinga conventional dispersion agent, such as a straight-chain polyacrylate.
