UTILISATION D'ESTERS D'ACIDES CARBOXYLIQUES ET D'ALKYLOLAMINES TERTIAIRIES POUR LE TRAITEMENT DE PIGMENTS ET MATIRES DE CHARGE INORGANIQUES DONT ON VEUT AMELIORER LA DISPERSABILITE

摘要

A process for improving the dispersibility of inorganic pigments and fillers which comprises contacting said pigments and fillers with esters of aliphatic carboxylic acids having 4 to 22 carbon atoms with tertiary alkylolamines, and recovering a highly dispersible pigment or filler.
