Abstract

Aqueous dispersions which contain a synthetic polymer obtained by free radical polymerization and a rosin are prepared by a process in which an aqueous dispersion of the synthetic polymer obtained by free radical polymerization is mixed with an aqueous formulation of a rosin which contains from 0.1 to 0.5 mol, based on 100 g of rosin, of carboxyl groups.
