Synergistic combinations of UV absorbers for pigmented polyolefins

摘要

The instant invention relates to a polyolefin composition which comprises d) at least one organic pigment e) at least one sterically hindered amine light stabilizer and f) as UV absorber a mixture of a 2-hydroxyphenyl benzotriazole and a 2-hydroxyphenyl-s-triazine. Further objects of the invention are a method for stabilizing pigmented polyolefins and the use of a UV-absorber mixture of a hydroxyphenyl benzotriazole with a hydroxyphenyl-s-triazine for the stabilization of pigmented polyolefins.
