Abstract: A process for the production of a dark-color multi-layer coating, comprising the successive steps:(1) applying an NIR-opaque coating layer A′ from a waterborne pigmented coating composition A to a substrate, (2) applying a coating layer B′ from a waterborne pigmented coating composition B onto the substrate provided with coating layer A′, (3) subjecting the coated substrate obtained in step (2) to a drying step, (4) applying a clear coat layer, and (5) curing the coating layers simultaneously; wherein both coating compositions A and B comprise aqueous microgel and sheet silicate, wherein the pigment content of coating composition A consists 90 to 100 wt. % of aluminum flake pigment and 0 to 10 wt. % of further pigment, wherein the pigment content of coating composition B consists 50 to 100 wt. % of black pigment with low NIR absorption and 0 to 50 wt. % of further pigment.
