FIELD: chemistry.SUBSTANCE: invention relates to use in paint of calcium carbonate which is obtained by dry-grinding in the presence of a grinding aid agent. Said agent is a copolymer containing a) 0.5-50% of at least one anionic monomer selected from acrylic acid, methacrylic acid and mixtures thereof, and b) 50-99.5% of at least one nonionic monomer taken in amount of 0.05-5% of the dry mass of calcium carbonate.EFFECT: paints containing calcium carbonate obtained using the described method have high viscosity stability with preservation of optical properties of the paints.7 cl, 3 tbl, 4 ex |
