Disclosed are blended latex dispersions which can be used as binders in paper coating compositions. Such latex dispersions comprise a first copolymer of a vinyl ester of an alkanoic acid having from 1 to 13 carbon atoms and ethylene; and a second copolymer of (i) styrene and butadiene, (ii) styrene, butadiene and acrylonitrile, or (iii) styrene and an acrylic monomer, wherein the first and second copolymers are colloidally dispersed in an aqueous medium comprising a surfactant. The paper coating compositions containing latex dispersion binders of this type preferably exhibit especially desirable coating strength as quantified by the Dry Pick Values which such compositions provide. |
