Method for producing color giving and/or effect giving lacquer coatings

摘要

Process for producing a color and/or effect coating system on a primed or unprimed substrate by applying an aqueous color and/or effect solid-color topcoat material or-alternatively-an aqueous color and/or effect basecoat material and a clearcoat material (wet-on-wet technique) to the substrate and curing the resultant coating films, which comprises (a) using an aqueous color and/or effect solid-color topcoat material or aqueous color and/or effect basecoat material which contains no metal flake pigments and which after curing gives a color and/or effect solid-color topcoat or aqueous basecoat having a water vapor permeability delta60° C.>6.0 mg/h m bar or delta60° C.>286.4 g 100 mum/m2 d, where d stands for day; or (b) using an aqueous effect or color and effect solid-color topcoat material or aqueous effect or color and effect basecoat material which comprises metal flake pigments and which after curing gives a color and/or effect solid-color topcoat or aqueous basecoat having a water vapor permeability delta60° C.>4.0 mg/h m bar or delta60° C.>190.92 g 100 mum/m2 d.
