ABSTRACT OF THE DISCLOSURE 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 Image (I) or Image (II), wherein R1 and R2 are alkyl having 1 to 21 carbon atoms, the sum of the carbon atoms in R1 and R2 being 6 to 22, R3 is hydrogen or methyl, provided there is only one methyl group per (CH)X group, R4 and R5 are the same or different and are hydrogen, alkyl hav- ing 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 o,1,2 or 3, the R1-CH-CH- R2 units in the aminoalkanols being of at least two different chain lengths of from 8 to 24 carbon atoms and the vicinal sub- stituents being distributed statistically along said chain lengths, with the proviso that, if y is o, R4 and R5 are not both hydrogen, or (b) salts, (c) alkoxylation products, and (d) quaternization products of said aminoalkanols, and recovering highly dispersible pigments and fillers. -A-
