    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.

    Abstract: Described is a process for preparing urethane (meth)acrylates. In a first step, a hydroxyalkyl (meth)acrylate (A) is reacted with a lactone (B) in the presence of at least one catalyst (C), selected from the group consisting of iron compounds, titanium compounds, aluminum compounds, zirconium compounds, manganese compounds, nickel compounds, zinc compounds, cobalt compounds, and bismuth compounds to provide a product; and, in a further step, the product is reacted with a polyisocyanate (D) which comprises at least one hydroxyalkyl (meth)acrylate bonded via an allophanate group.

    Abstract: Described are radiation-curable coating compositions which combine good hardness with high flexibility and enhanced tensile strength, as well as good tensile-at-break. The radiation-curable coating compositions comprise at least one urethane(meth)acrylate (A) having a molar mass Mn of 100 to 500 g/mol and two ethylenically unsaturated double bonds per molecular and at least one monoethtlyenically unsaturated reactive diluent (B) which contains at least one cycloaliphatic or heterocyclic group.
