Abstract
A latex binder for a pigmented paper coating, the latex including particles of an emulsion copolymer comprising (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, based upon the total weight of the mer units within the particle.
Claims15
