摘要： The present invention is directed to a process for producing precipitated calcium carbonate with improved resistance to structural breakdown, wherein the milk of lime is carbonated in the presence of at least one gas other than carbon dioxide, or the carbonation is carried out in the presence of a static gas bubble comminution unit as well as to precipitated calcium carbonate obtained by such a process.

摘要： The present invention relates to the use of a surface-reacted calcium carbonate as an anti-blocking agent in polymer(s) containing compositions, wherein the surface-reacted calcium carbonate is a reaction product of natural ground or precipitated calcium carbonate with carbon dioxide and one or more H3O+ ion donors in an aqueous medium, wherein the carbon dioxide is formed in situ by the H3O+ ion donors treatment and/or is supplied from an external source, an anti-blocking agent comprising surface-reacted calcium carbonate or a combination of surface reacted calcium carbonate and mineral material, a method for controlling the blocking of polymer(s) containing compositions, a polymer(s) containing composition comprising surface reacted calcium carbonate or a combination of surface reacted calcium carbonate and mineral material, a coating composition comprising such polymer(s) containing composition, as well as a substrate coated with such coating composition.

摘要： A process for the deinking of a coated paper or paperboard is disclosed, the process comprises a step of providing a coating layer comprising a calcium- or magnesium-exchanged clay which is deposited on the paper or paperboard before the ink layer. In a further step said calcium- or magnesium-exchanged clay is activated and the paper is subsequently treated with water.
