Uv-curable coating composition having improved sunlight stability

Abstract

What is described is a radiation-curable coating composition comprising polymerizable unsaturated compounds such as (meth)acrylates, vinyl compounds or the like in a concentration range of 15-98% by weight, with an addition of 5-35% by weight, preferably 5-20% by weight, of organic uv absorbers, where the uv absorber(s) have their maximum absorption level within a wavelength range of < 390 nm, preferably < 350 nm, where the coating composition optionally comprises further components in an amount of the residue to 100% by weight, and a method for curing such a coating composition. Also described is a coating composition of this kind, wherein the organic uv absorber is free-radically polymerizable.
