Abstract

Pigment particles are uniformly coated with from 1/2 to 4 per cent by weight of a water-insoluble, oil-soluble diacid salt of an N-aliphatic alkylene diamine of the general formula R-NH-(CH2)xNH2, the acid having the general formula R1COOH or R1-NH-A-COOH, R and R1 being aliphatic radicals, or a mixture of aliphatic radicals, having from 12 to 22 carbon atoms, x being an integer from 2 to 10, preferably 3, and A being a divalent aliphatic hydrocarbon radical of 2 or 3 carbon atoms. R may be a mixture of radicals derived from tallow, soya-bean oil or coconut oil. The acid may be, for example, oleic or N-coco-aminobutyric acid. The coating may be formed by adding separately to an aqueous pigment dispersion stoichemetric quantities of a water-soluble salt, e.g. the acetate or hydrochloride of the diamine and of an alkali metal salt of the acid and separating the coated pigment particles from the aqueous phase. As pigments iron blue, chrome yellow, chrome orange, chrome green, zinc chromate, red lead, azo type toners, aluminium hydrate, lakes, carbon black, iron oxide, zinc oxide, titanium-containing pigments, zinc-sulphide-containing pigments, white lead and extenders are mentioned.
