Abstract

A process for improving the dispersibility of inorganic and organic pigments and fillers which comprises contacting said pigments and fillers with (a) a mixture of aminoalkanols of the formulae ##STR1## wherein R.sub.1 and R.sub.2 are alkyl having 1 to 21 carbon atoms, the sum of the carbon atoms in R.sub.1 and R.sub.2 being 6 to 22, R.sub.3 is hydrogen or methyl, provided there is only one methyl group per (CH).sub.x group, R.sub.4 and R.sub.5 are the same or different and are hydrogen, alkyl having 1 to 4 carbon atoms or hydroxyalkyl having 2 to 4 carbon atoms, x is an integer of from 2 to 6 and y is 0,1,2 or 3, the R.sub.1 --CH--CH--R.sub.2 units in the aminoalkanols being of at least two different chain lengths of from 8 to 24 carbon atoms and the vicinal substituents being distributed statistically along said chain lengths, with the proviso that, if y is 0, R.sub.4 and R.sub.5 are not both hydrogen, or (b) salts, (c) alkoxylation products, and (d) quaternization products of said aminoalkanols, and recovering highly dispersible pigments and fillers.
