ABSTRACT Aqueous latexes of heterogeneous polymer particles comprising (1) a minor portion of a soft interpolymer domain having a glass transition temp- erature of less than 25°C and comprising a mono- vinylidene aromatic monomer such as styrene and an open chain aliphatic conjugated diene such as 1,3-butadiene and (2) a major portion of a relatively hard interpolymer domain having a glass transition temperature greater than 25°C and comprising a mono- vinylidene aromatic monomer and an open chain aliphatic conjugated diene monomer are useful as stiff binders for pigmented paper coating compositions and provide pigmented paper coatings having an improved combination of properties. 27,110-F
