Title of Invention

NOVEL INORGANIC PIGMENT CONTAINING CALCIUM CARBONATE, AQUEOUS SUSPENSION CONTAINING SAME, AND THE METHOD OF MANUFACTURING THE SAME

Abstract The present invention relates to the technical field of inorganic pigments containing a material formed in situ by a double and/or multiple reaction between a calcium carbonate and one or more products of a reaction between said carbonate and one or more medium- to high-strength H3O+ ion donors and one or more products of a reaction between said carbonate and gaseous CO2 formed in situ and/or supplied from an external source, and at least one aluminium silicate and/or at least one synthetic silica and/or at least one calcium silicate and/or at least one silicate of a monovalent salt such as sodium silicate and/or potassium silicate and/or lithium silicate, and/or at least one aluminium hydroxide and/or at least one sodium and/or potassium aluminate, containing less than 0.1 wt % of the monovalent salt silicate such as sodium, potassium or lithium silicate or mixtures thereof, based on the dry weight of the calcium carbonate, having a pH higher than 7.5 at 20 °C, and the uses thereof in paper-making applications such as adding a filler to and/or coating paper, particularly raw printing stock for offset printing in particular, or digital printing such as ink jet and/or laser printing.
