A synthetic polymeric latex comprising a major amount of vinyl acetate and minor amounts of an acrylic ester, at least one acrylic acid, and styrene is prepared by copolymerizing vinyl acetate with the acrylic ester and acid, to form a backbone polymer, and then grafting styrene onto the backbone polymer. Stable, aqueous, alkali-swellable emulsions of the synthetic polymeric latex can be prepared, and the latex can be used as a binder material in paper coating compositions to bind pigments to paper and paperboard.
