The present invention relates to Disclosed herein is a multilayer coating system being present on an optionally pre-coated substrate and including at least three coatings layers L1, L2 and L3 being different from one another, the first layer L1 applied on an optionally pre-coated substrate, the second layer L2 applied over L1, and the third top coating layer L3 applied over L2, where layer L1 is formed from a primer coating composition and layer L2 is formed from a basecoat composition different from the primer coating composition, where the primer coating composition is free of or essentially free of metal effect pigments. Further disclosed herein are a method of preparing the multilayer coating system, a kit-of-parts and a method of using the kit-of-parts for improving the LiDAR reflectivity, measured at an angle of incidence of 0?, and the flop index, of multilayer coating systems.

Disclosed herein is a multilayer coating including at least one ground coat layer, the at least one ground coat layer including at least one non-platelet-shaped titanium dioxide pigment (T); at least one midcoat layer on top of the at least one ground coat layer, and at least one clearcoat layer on top of the at least one midcoat layer; and having a lightness L* according to CIELab in the viewing angle range from ?15? to +45? of at least 80; in the viewing angle range from +75? to +110? of at least 70, if a metal effect pigment is contained in the midcoat layer; in the viewing angle range from +75? to +110? of at least 75, if no metal effect pigment is contained in the midcoat layer. Further disclosed herein are a method for producing such multilayer coating and a multilayer coated substrate.
