摘要： A coating pigment composition comprising a hydrous clay, a caustic leached calcined clay, and a porous mineral provides a coating having excellent balance of color intensity and color definition characteristics when printed on by multicolored inks. The pigments of this invention offer a low cost alternative to conventional silica-based coatings in addition to affording other desirable benefits such as improved rheology, less required coat weights, and higher coating solids compared to conventional silica coatings.
