The invention relates to coating agents based on one or more mineral binders, one or more polymers, one or more fillers, and optionally one or more additives. The invention is characterized in that the coating agents contain 0.05 to 5 wt. %, with respect to the dry weight of the coating agents, of one or more flexibilizers selected from the group comprising hydroxy compounds with 1 to 25 carbon atoms, carboxylic acid compounds with 1 to 25 carbon atoms or the salts thereof, hydroxy carboxylic acid compounds with 1 to 25 carbon atoms or the salts thereof, phosphonic acids or the salts thereof, and phosphoric acids or the salts thereof, and at least 55 wt % polymers, with respect to the dry weight of the polymers and the mineral binders.

1. A coating composition comprising: 2% to 30% of at least one mineral binder;20% to 55% of at least one polymer, which is obtainable by radically initiated polymerization of at least one ethylenically unsaturated monomer selected from the group consisting of vinyl esters, (meth)acrylic esters, vinylaromatics, olefins, 1,3 dienes and vinyl halides, and optionally further monomers copolymerizable therewith;10% to 70% of at least one filler;0.05% to 3% of at least one flexibilizer selected from the group consisting of tartaric acid, gluconic acid, citric acid, fructose and saccharose; and optionallyat least one additive,wherein all the above percentages are by weight based on a dry weight of the coating composition and total 100%, and wherein the at least one polymer is present in an amount of 60% to 98% by weight based on a dry weight of the at least one polymer and of the at least one mineral binder. 2. The coating composition of claim 1, wherein the coating composition comprises 70% to 98% by weight of the at least one polymer, based on the dry weight of the at least one polymer and of the at least one mineral binder. 3. The coating composition of claim 1, wherein the at least one polymer is selected from the group consisting of vinyl ester homopolymers, vinyl ester copolymers comprising one or more monomer units from the group encompassing vinyl esters, olefins, vinyl aromatics, vinyl halides, acrylic esters, methacrylic esters, fumaric and/or maleic monoesters or diesters, (meth)acrylic ester homopolymers, (meth)acrylic ester copolymers comprising one or more monomer units from the group encompassing methacrylic esters, acrylic esters, olefins, vinylaromatics, vinyl halides, fumaric and/or maleic monoesters or diesters, homopolymers or copolymers of dienes and ethene and optionally styrene, (meth)acrylic esters or the esters of fumaric or maleic acid, homopolymers or copolymers of vinylaromatics; and copolymers of vinylhalogen compounds. 4. The coating composition of claim wherein the coating composition comprises 30% to 50% by weight of the at least one polymer, based on the dry weight of the coating composition. 5. The coating composition of claim 4, wherein the at least one filler comprises a mixture of at least one silicatic filler and at least one carbonatic filler. 6. The coating composition of claim 5, wherein the coating composition comprises at least one additive selected from the group consisting of highly disperse silicas, phyllosilicates, pigments and fibers. 7. The coating composition of claim 1, wherein the coating composition comprises 30% to 50% by weight of the at least one polymer, based on the dry weight of the coating composition. 8. The coating composition of claim 1, wherein the at least one filler comprises a mixture of at least one silicatic filler and at least one carbonatic filler. 9. The coating composition of claim 1, wherein the coating composition comprises at least one additive selected from the group consisting of highly disperse silicas, phyllosilicates, pigments and fibers. 10. A process for producing a coating, said method comprising applying to a substrate at least one coating composition of claim 1. 11. The process of claim 10, wherein the coating has a coat thickness of 1 to 10 mm. 12. A coating composition comprising: 2% to 30% of at least one mineral binder;30% to 50% of at least one polymer, which is obtainable by radically initiated polymerization of at least one ethylenically unsaturated monomer selected from the group consisting of vinyl esters, (meth)acrylic esters, vinylaromatics, olefins, 1,3 dienes and vinyl halides, and optionally further monomers copolymerizable therewith;10% to 70% of at least one filler;0.05% to 3% of at least one flexibilizer selected from the group consisting of oxalic acid, tartaric acid, gluconic acid, heptonic acid, gallic acid, citric acid, succinic acid, sebacic acid, salicylic acid, pimelic acid, hematic acid, malic acid, salts of the aforementioned acids, pentaerythritol, sorbitol, sucrose, glucose, fructose, disaccharides, tetrasodium pyrophosphate, tetrapotassium pyrophosphate and sodium hexametaphosphate (Graham's salt); and optionallyat least one additive,wherein all the above percentages are by weight based on a dry weight of the coating composition and total 100%, and wherein the at least one polymer is present in an amount of 60% to 98% by weight based on a dry weight of the at least one polymer and of the at least one mineral binder.
