Abstract of the Disclosure Disclosed is method of preparing an essentially stable aqueous dispersion of from 25 to 50% or more rosin base material. The method involves homogenizing an unstable aqueous dispersion of rosin-base material, a relatively small amount of which is in the form of a soap, such as the sodium soap, of the rosin-base material, the soap serving as a dispersing agent for the unsaponified rosin-base material. The dispersions are useful in the sizing of paper. - 1 -
