PIGMENT COMPOSITION

摘要

The invention relates to an aqueous slurry or dispersion of pigment particles comprising as dispersant an amphiphilic polymer at least partly adsorbed to the pigment particles, wherein the slurry or dispersion exhibits a temperature dependent viscosity in such way that the viscosity increases at least with a factor of about 2 when the temperature is raised from about 20 up to about 100 DEG C. The invention further relates to a the preparation of the slurry or dispersion, a coating colour composition, a process for its preparation, a process for preparing coated paper or board, and paper or board obtainable by the process.
