ABSTRACT:
An emulsion polymerized latex copolymer used as a binder in paper-coating compositions with improved dry and wet binding strength comprising an ester of an ethylenically unsaturated carboxylic acid and a saturated alcohol and a hetero-unsaturated monomer selected from the group consisting of allyl acrylate, allyl methacrylate, crotyl acrylate or crotyl methacrylate. A paper-coating composition in the form of an aqueous dispersion comprising a pigment and said emulsion polymerized latex copolymer is further characterized in that said pigment is present in an amount from about 99 to about 77 weight percent based on total dry solids. A coated paper article in the form of a fibrous sheet coated on at least one surface with the paper-coating composition is also provided.
