    摘要: A coating composition may include kaolin having a shape factor less than about 70 and calcium carbonate, wherein less than about 90% by weight and greater than about 60% by weight of particles of the calcium carbonate have an equivalent spherical diameter (esd) less than 2 microns. The coating composition may include a thickener present in an amount ranging from about 0.1% to about 0.9% by active dry weight of the composition. A coating composition may include kaolin having a shape factor less than about 70 and calcium carbonate having a mean particle size (d50) of at least about 2.4 microns and a steepness factor of at least about 30. The coating composition may be a paper basecoat composition or a paperboard basecoat composition. A paper or paperboard product may include the coating composition on at least one surface of the paper product or paperboard product.

    摘要: The present invention relates to polyoxometalate-coated alumina trihydrate dispersants prepared by combining a polyaluminum chloride having certain characteristics with alumina trihydrate particles. Such dispersants are useful for forming cationic alumina trihydrate slurries, which can be mixed with titanium dioxide to produce stable cationic slurry blends useful in paper, paper-board, and paint (coatings) applications. The dispersants are also useful for preparing cationic titanium dioxide slurries.
