    摘要: 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.
