Abstract: Pigments are treated by contacting them with a mixture of (a) a resinic acid, e.g., colophony, or a salt of a resinic acid; and (b) a primary or secondary amine having the formula R-NH-R1 in which R is a five- to six-membered, optionally substituted cycloaliphatic radical; and R1 is hydrogen, R, or an alkyl group optionally substituted by an NH2 group and containing two to four carbon atoms, or by preparing the neutral or acidic aqueous pigment in the presence of the treating agents (a) and (b). The treated pigments exhibit advantages such as better gloss and covering power.
