Abstract

PURPOSE:To improve dispersion stability, by wet-grinding slurry comprised of, as raw material for wet-grinding, calcium carbonate having a property to precipitate which has been treated with specific treatment agents, and has specific value, and glycol. CONSTITUTION:Raw material is prepared by treating the surface of calcium carbonate having a property to precipitate which has a primary particle diameter D1 of at least 0.1mum calculated by an equation I (Dx: mean particle diameter mum of calcium carbonate having a property to precipitate, Sx: specific surface area cm<2>/g) using specific surface area S1 measured by BET method and has a particle distribution of predetermined value, with surface treatment agents comprising alpha,beta monoethylene unsaturated carboxylic acid etc. Glycol dispersion of calcium carbonate having a property to precipitate is produced by wet- grinding the glycol slurry comprising said raw material and glycol under specific conditions.
