Abstract

The invention relates to the use of water-containing organophilic phyllosilicates obtained by the reaction of a phyllosilicate, which is completely delaminated colloidally in water and is capable of cation exchange, with an organic onium salt in aqueous suspension and subsequent mechanical removal of the water, without drying by heating, as a rheological additive in organic media. The water-containing organophilic phyllosilicates are particularly suitable for coating paper.
