摘要： A deformable film has a decorative surface featuring a completely matt appearance. For this purpose, the deformable film has a decorative surface provided with at least one coating comprising the following constituents: (a) an aqueous dispersion of a hydroxy-functional prepolymer, obtainable by conversion of at least one of the following components: (i) a component having hydroxyl groups, (ii) a polyester polyol having hydroxyl groups, (iii) a polyisocyanate having isocyanate groups, (iv) a compound having at least two groups reactive toward isocyanate groups and at least one group capable of anion formation, (v) water, where components (i) to (iii) and the ratio of components (i) to (iii) are selected such that an excess of hydroxyl groups is present relative to the isocyanate groups, and (b) nanoparticles having a number-average particle size of 1 to 1000 nm and (c) a crosslinker having at least two groups reactive toward hydroxyl groups.

摘要： The present invention relates to a coating composition that is suitable in particular for the production of coatings that can be matted. The coating composition comprises a) an aqueous dispersion of a hydroxy-functional prepolymer, obtainable by reaction of at least the following components: i) a component comprising hydroxy groups, ii) a polyester polyol comprising hydroxy groups, iii) a polyisocyanate comprising isocyanate groups, iv) a compound which comprises at least two groups reactive towards isocyanate groups and at least one group capable of anion formation, v) water, wherein components i)-iii) and the ratio of components i)-iii) are so chosen that an excess of hydroxy groups is present relative to the isocyanate groups, b) nanoparticles having a number-average particle size of from 1 to 1000 nm, and c) a crosslinker comprising at least two groups reactive towards hydroxy groups. The invention further provides a process for the preparation of the coating composition, the use of the coating composition for producing a coating on a substrate, and a coating obtainable by applying the coating composition to a substrate.
