    摘要: Described is a method for coating light alloy rims, coating materials for use in this method, and the coated light alloy rims obtained in this way. More specifically, described is a method for coating light alloy rims with at least three layers comprising a primer layer (A), a base coat layer (B), and a clear coat layer (C), each of which are a layer of different coating materials. The method comprises providing a substrate; applying the primer layer (A) directly to the substrate; applying the base coat (B) layer; applying the clear coat layer (C); and curing the layers of different coating materials by high-energy radiation.

    摘要: Compounds having alcoholic hydroxyl groups are esterified with acrylic or methacrylic acid in the presence of copper(II) salts or mixtures thereof as polymerization inhibitors and in the presence of a hydrocarbon as a water-entraining agent with removal of the water of reaction at from 90 to 150° C. After the esterification, the copper salt is precipitated as copper sulfide and is separated off from the ester. The light-color (meth)acrylates resulting in the high yields are particularly suitable for coatings containing colored pigment on substrates such as wood, paper, mineral building materials, plastics or metal.
