Abstract

A pigment is dispersed in a water-immiscible organic medium by treating an aqueous solution of the pigment with cyclohexylamine or an N-substituted methyl, ethyl, phenyl or cyclohexyl derivative thereof in the presence of the organic medium. The amine may be primary, secondary or tertiary or an amine soap by reaction with a fatty or resin acid. Up to 5 per cent by weight on dry pigment of the amine is used. The pigment may be organic or inorganic and include iron blues, chrome yellows, organic lakes and pigment dyestuffs. Organic media specified include coal tar solvents, mineral spirits, hydrogenated naphthas, linseed oil, chinawood oil, soya bean oil, perilla oil, other vegetable and animal oils, synthetic and oleoresinous varnishes, mineral oil, petrolatum, castor oil and waxes. Soap-forming acids include oleic, stearic, palmitic, linolenic, ricinoleic, rosin and abietic acids. In examples, iron blue presscake, phospho-tung-state rhodamine lake, peacock blue, light chrome yellow, toluidine red toner and Lithol Red R are used.
