    Abstract: The present invention relates to a method for producing a multi-coat colour and/or effect paint system, by (1) applying a pigmented aqueous basecoat material to a substrate, (2) forming a polymer film from the coating material applied in stage (1), (3) applying a clearcoat material to the resultant basecoat film and subsequently (4) curing the basecoat film together with the clearcoat film. The method of the invention is characterized by in stage (1) a pigmented aqueous basecoat material is used which comprises a mixture M consisting of (K1) a branched alkane having 8 to 17 carbon atoms or a mixture of such alkanes, (K2) a branched alkane having 18 to 25 carbon atoms or a mixture of such alkanes and (K3) a water-miscible fluorinated polymer or a mixture of water-miscible fluorinated polymers, where ° the mixture M is present in an amount of 0.1% to 5% by weight, based on the weight of the aqueous basecoat material applied in stage (1); ° component (K1) is present in an amount of 34% to 94% by weight, based on the weight of the mixture M; ° component (K2) is present in an amount of 5% to 46% by weight, based on the weight of the mixture M; ° component (K3) is present in an amount of 1% to 20% by weight, based on the weight of the mixture M; ° components (K1) and (K2) have a degree of branching which corresponds to a ratio of the number of >CH- and -CH2 groups to the number of -CH3 groups of at least 25:75.

    Abstract: A coated substrate including a substrate having at least one surface: and, disposed on the surface, a first coating having a Pigment Volume Concentration ("PVC") higher than the critical PVC; and, disposed on said first coating, a clear matte second coating including from 1% to 99% by weight, based on the weight of the second coating, a particulate polymer having a particle diameter of from 0.5 microns to 30 microns is provided. Also provided are a method for providing a coated substrate and a method for improving the stain resistance of a coating having a PVC higher than the critical PVC
