Glycol dispersion of precipitated calcium carbonate

摘要

The present invention provides a glycol dispersion comprising calcium carbonate and glycol prepared by wet-grinding under the specified conditions a glycol slurry composed of glycol and calcium carbonate satisfying the specified dispersibility and particle size. The glycol dispersion of the present invention is good in dispersion stability in glycol and is capable of improving running property of audio tapes, video tapes, etc., thus contributing to improvement in properties such as sound and image.
