Abstract: Disclosed herein is a primer coating composition, which is free of or essentially free of metal effect pigments, including besides water and/or organic solvent(s), a film-forming polymer, optionally a crosslinking agent and further a pigment mixture P-C including in turn at least two kinds of pigments being different from one another, 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. Further disclosed herein are methods of forming a primer coating film and layer, an at least partially coated substrate, a multilayer coating system and a method for preparing the multilayer coating system.
