Beschreibung
Zusammenfassung:	The present invention relates to water-based coating composition comprising A) at least one water-dilutable polyurethane binder, B) optionally at least one curing agent, and C) at least one special effect-imparting pigment, characterised in that the at least one water-dilutable polyurethane binder is based on at least one polyhydroxyl compound, said polyhydroxyl compound comprises at least 50 % by weight of at least one polycarbonate polyol, which is liquid at 20°C, the % by weight are based on the total amount of the polyhydroxyl compound. The invention also relates to the use of the water-based coating composition as base coat composition in a multilayer coating comprising a layer of a base coat composition and a layer of clear coat composition thereon. The water-based coating composition can be used as special effect imparting base coat composition in a multilayer coating comprising a layer of a base coat composition and a layer of a clear coat composition thereon.
