Coarse pigment addition and high solids slurries comprising fine calcium carbonate particles for higher coating colour concentrations

摘要

Disclosed is an aqueous slurry comprising a mineral material which has a percentage by weight of particles having a diameter of less than 5.0 microns of from 98.5 percent to 90 percent , a percentage P2 by weight of particles having a diameter of less than 2.0 microns of from 96 percent to 80 percent, wherein the ratio of P2/P5 is from 0.98 to 0.85, and wherein the slurry has a solids content of more than 78 wt percent.
