coating composition for coatings that can be matted. The present invention relates to a coating composition which is suitable, in particular, for the production of coatings which can be forged. the coating composition comprises a) an aqueous dispersion of a hydroxy-functional prepolymer, obtainable by reacting 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 comprising at least two groups reactive with isocyanate groups and at least one group capable of anionic formation, v) water, in which components i) to iii) and the ratio of components i) a iii) are chosen such that an excess of hydroxy groups is present relative to the isocyanate groups, b) nanoparticles having an average numerical particle size of 1 to 1000 nm, and c) a crosslinker comprising at least two reactive groups with hydroxy groups. the invention further provides a process for preparing the coating composition, the use of the coating composition to produce a coating on a substrate, and a coating obtainable by applying the coating composition to a substrate |
