ABSTRACT:
The demands on the properties of pigments, in particular in the areas of emulsion paints and printing inks, which are continuously becoming more specific made it necessary to develop selective and environmentally safe dispersing and emulsifying agents and coupling auxiliaries.
The compounds according to the invention are alkoxylation products prepared from fatty amine dialkylenediamines which, if desired, are linked to give recurring structural units by means of esterification with dicarboxylic acids and in which, preferably, the hydroxyl end groups of these fatty amine alkylenediamine alkoxylates have been esterified with fatty acids, aromatic carboxylic acids and/or resin acids and any hydroxyl groups still present have been converted to the corresponding mono-ester-containing anionic radicals by means of dicarboxylic acids and sulfites.
The compounds according to the invention are suitable for a wide range of areas of application in the surfactant sector, for example in the preparation of azo pigments, emulsion paints and printing inks, for the improvement of coloristic and rheological properties. The compounds according to the invention are particularly environmentally safe owing to their biodegradability.
