The present invention relates to a method for producing an anticorrosion coating, wherein (1) an anticorrosion primer comprising (A) at least one organic resin as binder and (B) at least one synthetic layered double hydroxide comprising organic anions is applied directly to a metallic substrate and (2) a polymer film is formed from the anticorrosion primer applied in stage (1), the method being characterized in that the at least one synthetic layered double hydroxide (B) comprises at least one organic anion of the following formula (I): where R1 COO−, SO3−, R2/R3 NH2, OH, H. The present invention relates, furthermore, to coated metallic substrates coated by the method of the invention. The present invention relates not least to the use of the anticorrosion primer for use in the method of the invention for improving the corrosion resistance of metallic substrates.
