Abstract: The present invention is directed to a process for manufacturing a calcium carbonate product including the steps of (i) contacting calcium carbonate with of one or more zirconium compounds in an aqueous suspension and/or of an aqueous emulsion and/or of an aqueous solution to obtain a calcium carbonate-containing slurry, and (ii) dispersing the calcium carbonate-containing slurry to obtain a calcium carbonate product.

Abstract: The present invention is directed to an aqueous suspension and/or aqueous dispersion of calcium carbonate obtained by the process of manufacturing a calcium carbonate-containing slurry prepared by addition of one or more zirconium compounds, wherein the aqueous suspension and/or aqueous dispersion of calcium carbonate consists essentially of calcium carbonate, water, one or more zirconium compounds and optionally, one or more phosphate-free additives acting as dispersion and/or grinding aid agents.

Abstract: The invention relates to novel and innovative PCC pigments, able to be used in a paper coating formulations to manufacture coated “multipurpose” papers, in particular for inkjet applications, whose print qualities would be identical or quite similar to high resolution commercial papers, while maintaining a reduced paper manufacturing and production cost. Said pigments are obtained by a carbonation process using a reduced flow rate of CO2/air, which leads to porous agglomerates of PCC of a very specific structure and unique properties, followed by an upconcentration step leading to substantially the same agglomerates but with a higher, appropriate, solids content.

Abstract: Novel and innovative PCC pigments, having a reduced production cost, able to be used in a paper coating formulations to manufacture coated high-quality matt papers, in particular for inkjet applications. Process for the preparation of same, using a reduced flow rate of a carbon dioxide-containing gas in the PCC carbonation step, which produces stable, porous, agglomerates of PCC featuring unique properties and structure, this step being followed by an upconcentration step to increase the solids content.

Abstract: It is an object of the present invention to provide a process of manufacturing calcium carbonate-containing slurries, wherein said calcium carbonate-containing slurries are prepared by adding one or more zirconium compounds, and possibly one or more further phosphate-free additives acting as dispersing and/or grinding aid agents. An other object of the invention lies in calcium carbonate-containing slurries thus obtained, and dry calcium carbonate mineral pigments resulting from the drying of such slurries. A further object of the invention is the use of such slurries and such dry mineral pigments in paper manufacturing, plastic coatings, as fillers for plastics or for aqueous paint compositions and the like. Papers, paints and plastics containing such slurries and such dry pigments are also an object of the present invention.

Abstract: The present invention relates to the technical mineral matter suspension sector, and, before and/or after drying, their applications in the fields of paper, paint and, after drying, plastics. It also relates to the use of a copolymer having at least one alkoxy or hydroxy polyalkylene glycol function grafted onto at least one ethylenically unsaturated monomer, as agent whose role is to enhance the gloss of the final product and, in particular, the gloss of the sheet of paper, irrespective of the viewing angle.
