摘要:
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.

A propylene oxide polyadduct containing carboxyl groups, or a salt thereof, obtained from(a) an adduct of propylene oxide and an aliphatic alcohol having 3 to 10 carbon atoms which is at least trihydric,(b) an aliphatic dicarboxylic acid or the anhydride thereof having 2 to 10 carbon atoms or a mono- or di-lower alkylester of said dicarboxylic acids,(c) an aliphatic diol having an average molecular weight of at most 2,000,(d) a fatty acid having 8 to 22 carbon atoms and(e) an aromatic dicarboxylic acid or the anhydride thereof having 8 to 12 carbon atoms; it is in particular useful as dyeing assistant for the dyeing of fibrous material made of or containing wool with anionic dyes.
摘要:
Oxalkylates of chemically modified natural rosin acids are useful for dyestuff preparations, especially for dispersions of disperse dyestuffs. The liquid and solid dyestuff preparations containing these oxalkylates are stable to storing even with high dyestuff concentrations, easily redispersible while developing little foam and easily biodegradable.
