Abstract:
1. A latex binder for a pigmented paper coating, the latex including emulsion copolymer particles, said copolymer comprising, based on the total weight of constituent mer units, (i) from about 15 to about 35 weight % mer units deriving from the polymerization of acrylonitrile; (ii) from about 25 to about 65 weight % mer units deriving from the polymerization of conjugated diene monomer; and (iii) from about 5 to about 55 weight % mer units deriving from the polymerization of alkenyl aromatic monomer, where the emulsion copolymer particles have a weight average diameter of greater than 150 nm.
