摘要： The invention relates to a method for treating particulate pigments, which comprises the following steps: a) mixing the particulate pigments with at least one non-ionic surface-active substance, b) dispersing the mixture of particulate pigments and non-ionic surface-active substance thus obtained in an aqueous medium, c) polymerizing at least one first monomer or copolymerizing a first mixture of comonomers in the presence of a dispersion according to b), whereby water-insoluble polymer or copolymer is formed on the surface of the particulate pigments, and d) adding at least one second monomer or one second mixture of comonomers and polymerizing or copolymerizing the same.
