Abstract

The present invention relates to a radiation-curable coating composition, especially for producing a scratch-resistant coating on polycarbonate surfaces, comprising at least one urethane acrylate of an isocyanurate trimer of 1,6-hexamethylene diisocyanate and butanediol monoacrylate. The invention also relates to a method for producing scratch-resistant coatings on polycarbonate surfaces, to the use of the coating composition, and to a substrate coated accordingly.
