Abstract

Solid pigment formulations containing from 70 to 97% by weight, based on the total weight of the formulation, of one or more pigments and also from 3 to 30% by weight, based on the total weight of the formulation, of at least one surfactant which is an adduct of ethylene oxide and optionally propylene oxide with ethylenediamine, the proportion of ethylene oxide being from 46 to 100% by weight, based on the total weight of ethylene oxide and propylene oxide in the adduct, and the adduct having an average molecular weight of from 5000 to 40,000, are useful for pigmenting printing ink and gloss paint compositions.
