ABSTRACT:
This invention provides a process for preparing an aqueous dispersion of a rosin-base material by an inversion method, the process being characterized in that the dispersant is at least one of compounds represented by the formula ##STR1## wherein R is straight-chain or branched-chain alkyl or alkenyl group having 10 to 24 carbon atoms, n is an integer of 4 to 25, one of X and Y is --SO.sub.3 M and the other thereof is hydrogen atom, and M is a monovalent cation.
The aqueous dispersion obtained by the process of the invention have excellent sizing effects, very high stabilities and greatly reduced foaming propertie
