  • Compositions of calcium carbonates/pigments for paper formulations, showing print through reduction
    Patent number: 8580082
    Abstract: The present invention relates to mixtures of two distinct porous, stable aggregates and rather coarse PCCs (precipitated) calcium carbonate pigments (such as a composition comprising a blend or mix of one of the two Grade B or Grade C PCCs, in combination with a second, specific S-PCC (S=scalenohedral type PCC) pigment in a ratio appropriately selected between 90/10 and 10/90 percent by dry weight, namely 80/20 and 20/80, with a coarser, third component, which may be a pigment and/or a filler such as natural calcium (ground) carbonate or (most preferably) a PCC (precipitated calcium carbonate), depending on the granulometry of the two fine PCCs the third, coarser component, may be omitted.
