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 [Figure] (I) or [Figure] (II), wherein R1 and R2 are alkyl having 1 to 21 carbon atoms, the sum of the car
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 [Figure] (I) or [Figure] (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 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 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 substituents being distributed statistically along said chain lengths, with the proviso that, if y is 0, 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.
