Abstract
Bimodal latexes having two separate and distinct particle size distributions have high solids content, good high shear rheology and good low shear viscosity. These bimodal latexes, e.g., styrene/butadiene/acrylic acid/itaconic acid latexes are employed in coating paper in conjunction with a mineral filler using a coating device such as a blade coater to yield high quality coatings which can be easily applied.
