    Abstract: The present invention relates to surface-modified nanoparticulate metal oxides where the metal is chosen from the group consisting of aluminum, cerium, iron, titanium, zinc and zirconium, wherein the surface modification comprises a coating with a copolymer P comprising, as monomers, A) 1 to 99 mol % of a N-vinylamide N-vinylpyrrolidone and B) 99 to 1 mol % of a monomer comprising, per molecule, a free-radically polymerizable α,&bgr;-ethylenically unsaturated double bond and an anionogenic and/or anionic group, with the proviso that the copolymer P must comprise no further monomers chosen from the group consisting of C8-C30-alkyl esters of monoethylenically unsaturated C3-C8-carboxylic acids, N-alkyl- or N,N-dialkyl-substituted amides of acrylic acid or of methacrylic acid with C8-C18-alkyl radicals, or vinyl esters of aliphatic C8-C30-carboxylic acids.

    Abstract: The present invention relates to a particulate, linear, sheet-like or three-dimensional structure comprising, at least on its surface, a hydrophilicizing amount of at least one acylated polyamine, where at least some of the polyamine nitrogen atoms bear acyl radicals of the formula I R 1 -CO- (I) where R 1 is hydrogen, C 1 -C 27 -alkyl, C 7 -C 27 -alkenyl or C 6 -C 10 -aryl, and where the alkyl, alkenyl and aryl groups may bear at least one substituent selected from the class consisting of hydroxyl, alkoxy, alkoxycarbonyl and NE 1 E 2 , where E 1 and E 2 may be identical or different and are hydrogen, alkyl or acyl, to the use of acylated polyamines for modifying the surface properties of solids, and also to a process for modifying the surface properties of particulate, linear, sheet-like, or three-dimensional structures.
