Abstract: A synergistic stabilizer mixture comprising a component a) and, for example, a component b), where component a) is at least one compound of the formula I 1

Abstract: The novel transparent polyolefin, polyester or polyamide article disclosed is stabilized against the effects of light, oxygen, heat and aggressive chemicals by addition of 0.005-0.30 % by weight the polymeric substrate of a hydroxyphenyl triazine UV absorber, and is characterized by its thickness between 1 and 500 &mgr;m. Preferred polyolefin articles thus stabilized are agricultural films containing as further stabilizer a sterically hindered amine. The novel compositions act as selective UV filter especially useful in agriculture.
