Abstract

The invention relates to mixtures of nitrogen-containing surface-active agents which are obtained by esterification of oxyalkylates based on modified or nonmodified naturally occurring resin acids or resin amines or resin alcohols derived therefrom with dicarboxylic acids or anhydrides thereof and subsequent reaction with alkylenediamines or alkylenepolyamines. These nitrogen-containing surface-active agents are suitable as coupling auxiliaries, emulsifiers, dispersing agents, preparation agents for solids dispersions, corrosion protection and metal-working agents and as wetting agents and dyeing auxiliaries.
