  • Paper coating pigments
    Publication number: 20060292305
    Abstract: The present disclosure relates to a coating composition for use in producing a coating on paper and other substrates comprising an aqueous suspension of a particulate pigment together with a binder, wherein the particulate pigment comprises a mixture of: a first pigment component comprising particulate ground calcium carbonate (GCC) having a particle size distribution (psd) steepness factor ranging from about 30 to about 45; and a second pigment component comprising particulate precipitated calcium carbonate (PCC) having a psd steepness factor ranging from about 55 to about 75. The particulate pigment may optionally further include a particulate kaolin clay.

  • Cationic carbonate pigment for ink jet coating ink receptive layer
    Publication number: 20060137574
    Abstract: The present invention relates to new pigment compositions, coating compositions and methods for making the new compositions, such as coatings for ink jet receiving materials. The coated inkjet receiving material can provide improved printability. The pigment composition can be prepared by dispersing a carbonate pigment with at least one anionic dispersant The predispersed carbonate can then combined with at least one cationic polymer, such as a polyquaternary ammonium polymer or polyamine capable of being converted to a polyquaternary ammonium polymer.

  • Grinding method
    Publication number: 20060106118
    Abstract: The invention provides a method of grinding an inorganic particulate material such as calcium carbonate or kaolin in an aqueous suspension, preferably at a solids level below about 50% by weight, wherein the aqueous suspension includes a sub-effective amount of a dispersing agent for the inorganic particulate material.
