ABSTRACT:
This invention provides a rosin emulsion sizing agent for papermaking comprising a fortified or unfortified rosin-epoxy compound obtained by reacting a rosin and an epoxy compound, wherein the rosin-epoxy compound is dispersed in water with the aid of an emulsifying and dispersing agent, and paper sized therewith and a method of sizing using the same. The rosin emulsion sizing agent of the present invention exhibits an distinguished sizing effect in neutral papermaking systems even when calcium carbonate is contained therein and is excellent in mechanical and storage stabilities while causing little foaming in the papermaking system. In addition, the sizing agent presents no significant difficulties in its production.
