Abstract

PURPOSE: To obtain at a low cost the titled stable dispersion with a good sizing effect, by forming a W/O emulsion by the addition of a specified aq. dispersant soln. to a soln. of a melt reinforced rosin in an org. solvent, inverting the W/O emulsion and distilling the org. solvent off.
CONSTITUTION: The titled dispersion is prepd. in three steps by forming emulsion (A) in which a reinforced resin forms a continuous phase and water forms a dispersed particle phas by the admixture of a melt-reinforced rosin with a water- miscible org. solvent and then additionally with an aq. soln. contg. a dispersant consisting of a compd. of formulaIor II (wherein R is 10W24C alkyl phenol or alkyl; n is 6W20; X is Na, K or NH4) followed by dissolution, then forming emulsion (B) in which the reinforced resin forms a dispersed particles phase and the water forms a continuous phase by the agitation of the emulsion A with addition of water, and distilling the water-immiscible org solvent off from the emulsion (B) under reduced pressure. A fine and stable rosin material with a good sizing effect which contains no materials inhibiting its sizability, such as casein, soybean or protein, and requires no high temp. or pressure in preparation, is obtd.
