Abstract
Disclosed herein is a multilayer coating system present on a substrate and including at least three coating layers L1, L2 and L3 different from one another, namely a first pigmented coating layer L1 applied over at least a portion of the substrate, a second coating layer L2 applied over the first pigmented coating layer L1, and a third coating layer L3 applied over the second coating layer L2, where the second coating layer L2 is formed from a coating composition including at least one block copolymer containing a backbone and at least two blocks B1 and B2 and side chains S1 and S2 including different polymeric moieties M1 and M2. Also disclosed herein are a method of preparing said multilayer coating system, a coated substrate obtainable therefrom, and a method of using a coating composition including the block copolymer for improving the chromaticity of the multilayer coating system.
