A surface-reacted calcium carbonate is described. In embodiments, the surface-reacted calcium carbonate is obtained by a process comprising treating a calcium carbonate-comprising material with at least one HOion donor, carbon dioxide, and at least one water-soluble metal cation source in an aqueous medium to form an aqueous suspension of surface-reacted calcium carbonate.

Surface-reacted calcium carbonate with functional cations

A process of producing a surface-reacted calcium carbonate is described. In embodiments, a calcium carbonate-comprising material is treated with at least one HOion donor, carbon dioxide, and at least one water-soluble metal cation source in an aqueous medium to form an aqueous suspension of surface-reacted calcium carbonate. A surface-reacted calcium carbonate obtained by said process and its use are also described.

The present invention relates to a modified mineral-based filler comprising at least one alkaline earth metal carbonate-comprising material, and at least one water insoluble copper salt comprising the copper mineral malachite in an amount of at least 10 wt.-%, which covers at least partially the surface of the at least one alkaline earth metal carbonate-comprising material, and a method of producing the same.
