    Abstract: The present invention relates to coatings that possess a dynamic contact angle hysteresis in water, measured by means of a Wilhelmy balance according to DIN EN 14370, of at most 15°, and are can be manufactured from star-shaped prepolymers and/or star-shaped prepolymer-nanoparticle complexes that are cross-linkable with one another and with the surface of the substrate to be coated, the star-shaped prepolymers and/or star-shaped prepolymer-nanoparticle complexes possessing, before being cross-linked, at least three hydrophilic polymer arms that, considered of themselves, are soluble in water, and that carry on all or on some of their free ends R1 silyl terminal groups of the following general formula (I): R1 is —CRa2—Si(ORb)r(Rc)3-r, where Ra denotes hydrogen or a linear or branched alkyl group having 1 to 6 carbon atoms, ORb denotes a hydrolyzable group, Rc denotes a linear or branched alkyl group having 1 to 6 carbon atoms, and r denotes a number from 1 to 3, and that carry, on the optionally present ends not carrying silyl terminal groups, reactive groups that are reactive with respect to themselves, the substrate to be coated, entities optionally introduced into the coating, and/or with the silyl terminal groups. The present invention furthermore relates to a method for manufacturing such coatings, and to star-shaped prepolymers that are used in the coatings. The invention moreover relates to use of the star-shaped prepolymers as additives to various agents for temporary or permanent anti-soiling finishing of surfaces.
