ABSTRACT OF THE DISCLOSURE An improved inversion process for the preparation of a paper sizing agent which is an aqueous dispersion con- taining a high content of free rosin in the form of fortified rosin and/or non-fortified rosin, water, and an anionic dis- persing agent is disclosed. The improvement comprises using as the dispersing agent a polyethoxylated, sulfated rosin or a derivative thereof. There is also disclosed an aqueous dis- persion useful as a paper sizing agent comprising from about 10 to about 60% of fortified and/or non-fortified rosin, from about 1 to about 10% of a polyethoxylated, sulfated rosin or a derivative thereof, based on the total weight of all solids in the dispersion, and a sufficient amount of water to form a dispersion.
