Abstract

The present invention relates to a method for coating light alloy rims, to coating materials for use in this method, and to the coated light alloy rims obtained in this way. A primer layer, a base coat layer, and a clear coat layer are applied to a machined light alloy rim blank. The primer layer includes a radiation-curable coating material having an acid number of 10 to 120 mg KOH/g. The clear coat layer has a double-bond density of free-radically polymerizable reactive groups per unit mass of coating material of at least 1 mol/kg. The coating materials can be cured by radiation.
