Zastosowanie słabo jonowego kopolimeru, aktywator połysku, sposób rozdrabniania materiału mineralnego, wodna zawiesina materiału mineralnego i jej zastosowanie oraz sposób wytwarzania powłok barwnych

摘要

The use of a weakly ionic, water-soluble copolymer (A) is claimed as brightness activator at any angle of vision (i.e. at an angle of 20-85 (preferably 45-75) [deg]), where (A) is derived from at least one ethylenically unsaturated monomer (I) on which at least one alkoxy- or hydroxy-polyalkylene glycol function is grafted. Independent claims are included for: (a) an agent for activating brightness as above, comprising at least one copolymer (A); (b) methods for dispersing or milling minerals (B) in aqueous suspension, using (A); (c) aqueous suspensions of dispersed or milled (B), which contain (A); (d) a method for producing bulk coating slurries, using (A); and (e) coating slurries, which contain (A).
