Abstract:
What are described are coating compositions comprising pigments and/or fillers and multistage polyvinyl ester dispersions as binders. These binders are produced by a selected multistage process in which a polyvinyl ester dispersion is obtained in a first stage, monomers in dissolved or pure form or in the form of an emulsion are added to the reaction mixture in a second stage and then the polymerization is started again. The polyvinyl ester dispersions comprise polymerized silanes and/or epoxides or the polyvinyl ester dispersions have only a small content of protective colloids, if any. The coating compositions formulated with the multistage polyvinyl ester dispersions obtained in this way are notable for a very high weathering resistance.
