Abstract
An aqueous dispersion of a solid, especially a disperse dyestuff or a pigment, containing, as dispersing agent, a water-soluble, non-ionic polycyclic aromatic compound having a poly(lower alkylene-oxy)chain containing from 5 to 30 lower alkylene-oxy groups. Preferred dispersing agents contain about 10 ethylene-oxy groups in the chain. The dispersions of disperse dyestuffs are especially suitable for use in aqueous print pastes based on synthetic thickening agents and the pigment dispersions are suitable for use in emulsion paints.
