Beschreibung
Zusammenfassung:	The present invention relates to a multilayer coating system being present on an optionally pre-coated substrate and comprising at least three coatings layers L1, L2 and L3 being different from one another, the first layer L1 applied an optionally pre-coated substrate, the second layer L2 applied over L1, and the third top coating layer L3 applied over L2, wherein layer L1 is formed from a primer coating composition and layer L2 is formed from a basecoat composition different from the primer coating composition, wherein the primer coating composition is free of or essentially free of metal effect pigments, but inter alia comprises a pigment mixture P-C comprising at least two kinds of pigments, namely at least one organic black or inorganic black pigment P-C1, which is not a carbon black pigment, and which is transparent or substantially transparent to NIR-radiation or which is reflective or substantially reflective to NIR-radiation, and at least one inorganic white pigment P-C2, which is reflective or substantially reflective to NIR-radiation, and wherein the base coat composition inter alia comprises at least one pearlescent or interference pigment B-C1, which is present in an amount that exceeds the amount of any aluminum metal effect pigment(s) B-C2 optionally also present therein, a method for its production, a kit-of-parts and a use of said kit-of-parts for improving the LiDAR reflectivity,measured at an angle of incidence of 0°, and the flop index, of multilayer coating systems. La présente invention concerne un système de revêtement multicouches présent sur un substrat éventuellement pré-revêtu et comprenant au moins trois couches de revêtement L1, L2 et L3 différentes les unes des autres, la première couche L1 étant appliquée sur un substrat éventuellement pré-revêtu, la deuxième couche L2 étant appliquée sur L1 et la troisième couche de revêtement supérieur L3 étant appliquée sur L2, la couche L1 étant formée à partir d'une composition de revêtement d'apprêt et la couche L2 étant formée à partir d'une composition de couche de base différente de la composition de revêtement d'apprêt, la composition de revêtement d'apprêt étant exempte ou sensiblement exempte de pigments à effet métallique, mais comprenant entre autres un mélange de pigments P-C comprenant au moins deux types de pigments, à savoir au moins un pigment noir organique ou un pigment noir inorganique P-C1, qui n'est pas un pigment de noir de carbone, et qui est transparent ou sensibleme
