Abstract
A coating composition, in particular for producing the transparent topcoat of a multilayer coating. The coating composition contains as binders two acrylic polymers, A and B, as well as aliphatic and/or cycloaliphatic polyisocyanates. Acrylic polymer A has a molecular weight of 800 to 4,000, a hydroxyl number of 80 to 180 and a glass transition temperature of below -10.degree. C. Acrylic polymer B has a molecular weight of 3,000 to 10,000, a hydroxyl number of 40 to 120 and a glass transition temperature of -10.degree. C. to +10.degree. C. Whereas in acrylic polymer A the proportion of acrylic acid esters predominates, polymer B contains methacrylic acid esters as predominant monomer components.
