Abstract:
1. A process for manufacturing a hydrophobic salt of a layer-like metal hydroxide comprising the step of adding to a layer-like metal hydroxide salt containing trivalent, divalent and, optionally, monovalent metal cations, and one or more organic anions A of the formula (1) wherein X is hydrogen, hydroxyl, carboxyl, sulfato or sulfo; Y is carboxyl, sulfato or sulfo, and R is an aliphatic, cycloaliphatic, heterocycloaliphatic, olefinic, cycloolefinic, heterocycloolefinic, aromatic, heteroaromatic, araliphatic or heteroaraliphatic radical having 2 to 50 carbon atoms, wherein one or more substituents selected from the group consisting of hydroxyl, amino, halogen, C in a dispersion, with intensive thorough mixing, one or more hydrophobic compounds selected from the group consisting of waxes metal soaps or a mixture thereof in an amount of from 0.2 to 200 wt. %, based on the metal hydroxide salt, and optionally removing the liquid medium to form a product, optionally drying the product and optionally isolating the product as a powder, wherein the metal soap is a compound selected from the group consisting of di-, tri- or tetravalent metals salts of saturated or unsaturated C wherein the metal soap is a compound selected from the group consisting of di-, tri- or tetravalent metals salts of C
