Abstract
The invention relates to a process for the production of a multicoat coating of the basecoat/clearcoat type using a water-dilutable basecoat composition. The process comprises a basecoat composition which contains 0.1 to 4.0% by weight, based on the binder solids, of xanthan gum and 5 to 80% by weight, based on the binder solids, of crosslinked polymeric microparticles prepared from polyester polyols and polyisocyanates.
