Abstract
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.
