Process for preparing an essentially stable aqueous dispersion of rosin-based material, adapted for use in gluing cellulose fibers for papermaking, comprising homogenizing under a pressure of about 141 kg/cm 2 manom. At about 560 kg/cm 2, and at a temperature from about 150ºC to about 1-5º c, an unstable aqueous dispersion containing, by weight, about 5% to about 25% solids, the solids essentially consisting of, by weight, from 0% to about 95% rosin and from 100% to about 5% of an adduct reaction product of rosin and an acid compound containing the group (see formula) being the amount of acid compound that enters the adduct from about 1% to about 20% of the total weight of solids, characterized in that the process is carried out in the presence of an anionic dispersing agent.
