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 IR1—CO—  (I)where R1 is hydrogen, C1–C27-alkyl, C7–C27-alkenyl or C6–C10-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 NE1E2, where E1 and E2 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.
