ROSIN DISPERSIONS OF IMPROVED STABILITY

摘要

Colloidal aqueous dispersions of rosin possess improved mechanical- and heat-stability when they have a small dissolved content of a water-dispersible hydrophobic-hydro-philic emulsifying agent carrying at least one sulfo substituent, at least one carboxy substituent and at least one alkly hydrophobic substituent of at least 6 carbon atoms as agent improving the mechanical stability of said dispersion.
