| description | The invention relates to coating compositions and to their use for the production of transparent top coats on multilayer coatings. The coating compositions contain a mixture of A) 40-60% by weight of hydroxyl-containing (meth)acrylic copolymers obtainable by copolymerisation of a1) 50-70% by weight of one or more acrylic esters mixed with such a proportion of one or more hydroxyalkyl acrylates that the hydroxyl number is 40-70 mg of KOH/g and a2) 30-50% by weight of one or more methacrylic esters mixed with one or more hydroxyalkyl methacrylates in such a proportion that the hydroxyl number is 180-450 mg of KOH/g, and B) 60-40% by weight of hydroxyl-containing (meth) acrylic copolymers obtainable by copolymerisation of b1) 27-40% by weight of one or more alkyl acrylates, b2) 49-55% by weight of one or more methacrylic esters mixed with such a proportion of one or more hydroxyalkyl methacrylates that the hydroxyl number is 240-300 mg of KOH/g, b3) 1-3% by weight of acrylic acid and b4) 10-15% by weight of vinyl esters of aliphatic, saturated monocarboxylic acids in which the carboxyl group is bonded to a tertiary carbon atom. |
