FIELD: manufacturing technology.

SUBSTANCE: invention relates to anhydrous coating material compositions. Anhydrous coating material composition is proposed, comprising (A) at least one component, which contains a polyhydroxyl group (A), (B1), at least one component containing an isocyanate group and a component containing a silane group (B1) -X-Si-G_3-x, where G represents identical or different groups, selected from an alkoxy group, X represents alkyl, in particular one having from 1 to 6 carbon atoms, x is 0, (D), at least one catalyst (D) for cross-linking silane groups, wherein the composition comprises (B2) at least one component, containing a group of isocyanate (B2), which is different from component (B1) and which further comprises at least one perfluoroalkyl group of formula (I), wherein R¹ and R² independently of one another represents H, F and/or CF₃, but R¹ and R² can not both be H, and f is 1–20, preferably 3–11, more preferably 5–7. Multilayer color system using this composition, a method for its preparation and use are also provided.

EFFECT: technical result – the proposed composition makes it possible to obtain easily cleanable coatings with high scratch resistance and ability to maintain a high level of gloss retention.
