ABSTRACT:
Resin emulsions are prepared by forming an emulsion of an aqueous solution of an unsaturated material reactive with the resin in the liquid resin, causing the material and the resin to react and adding sufficient water to invert the emulsion to form an emulsion of the reacted resin in water to produce emulsions with improved mechanical stability useful as tackifiers in water-based pressure-sensitive adhesive coating materials in high speed coating lines giving reduced deposits and extended coating times.
