Abstract
There is disclosed an emulsion composition which comprises an aqueous emulsion (A) obtained by emulsion polymerization of 100 parts by weight of an ethylenically unsaturated monomer in the presence of 1 to 15 parts by weight of a carboxyl group-modified polyvinyl alcohol such as itaconic acid-modified polyvinyl alcohol as the dispersant and a polyamide resin (B) such as polyamide epichlorohydrin. The above emulsion composition has a long pot-life and can easily be made into a film having a high wet strength and being excellent in water resistance, hot water resistance and heat resistance. Accordingly, it can effectively be utilized in a variety of applications including paint coating, adhesive, fiber sizing agent and paper coating.
