Abstract: Described herein is a coating composition including at least one graphene oxide including at least one monovalent metal ion selected from the group consisting of lithium, potassium and mixtures thereof (GO-M), at least one binder B and/or at least one silane compound SC, and at least one solvent S1. Also described herein is a process to produce the coating composition, a method to produce at least one coating layer on a substrate by using the coating composition and a coating layer or multilayer coating obtained by said method. Also described herein is a method of using graphene oxide including at least one monovalent metal ion selected from the group consisting of lithium, potassium and mixtures thereof in coating compositions to improve corrosion resistance of said coating compositions.
