The salts are best employed as additives to the surfactant prior to addition of surfactant to molten rosin during preparation of the aqueous dispersion. Selected chlorides, fluorides, nitrates and sulfates of aluminum, calcium, cobalt, lead, magnesium, sodium and tin are disclosed as being effective within a range of about 0.01% to 0.1% by weight of rosin at a surfactant level of about 3.5%. Aluminum nitrate at a level of 0.04 to 0.055% by weight of the rosin, at a surfactant level of 3.5%, is preferred.
