Un dernier objet de l'invention est l'utilisation des matières minérales traitées à partir du procédé selon l'invention, comme agent réducteur de Ia quantité de colloïdes naturels et organiques dans Ie procédé de fabrication de Ia feuille de papier.
Abstract:
The invention relates to coating materials containing mixed oxide nanoparticles, an organic binder and optionally additives, wherein said coating materials contain nanoparticles consisting of 50-99.9 % by weight aluminium oxide and 0.1-50 % by weight oxides of elements of main groups I or II of the periodic table. The mixed oxide nanoparticles can also have a surface modified by another coating agent, preferably silane or siloxane. The inventive mixed oxide nanoparticles provide the coating materials or coatings with an improved scratch resistance.
Abstract:
The invention relates to metal effect pigments comprising a coating and a lamellar substrate. The coating is provided with at least one mixed inorganic/organic layer which contains, at least in part, an inorganic network encompassing one or several inorganic oxide components, and at least one organic component which at least partly represents an organic oligomer and/or polymer that is covalently bonded at least in part to the inorganic network via one or several organic network formers. The invention also relates to a method for producing said metal effect pigments and the use thereof.
Abstract:

Abstract:
Disclosed are metal oxide sols made by mixing at least one metal alkoxide, wherein the metal is a transition metal, a post-transition metal, an alkali metal, or alkaline earth metal; at least one organosilane; at least one boron oxide compound selected from the group consisting of boric acid, alkoxy boron compounds, hydrocarbyl boric acids, hydrocarbyl hydroxy boron alkoxides, and hydroxy boron alkoxides; and a liquid. Also disclosed are composites containing a polymer and the metal oxide sols.
Abstract:
Mineral dispersions are disclosed that are useful matting agents for incorporation into coating compositions. The dispersions are especially useful to provide relatively low gloss and relatively clear UV cure coatings. The dispersions contain carboxymethylcellulose acetate butyrate, at least one solvent, and at least one mineral. Though a wide variety of minerals can be used, a preferred mineral is silica. Also disclosed are methods of making such dispersions.
