Beschreibung
Zusammenfassung:The invention relates to stabilizer compositions for stabilizing polymeric organic materials, having a stabilizing amount of at least one co-active agent, and a stabilizing amount of an ultraviolet light absorber chosen from an ortho-hydroxyphenyl triazine, a benzoxazinone, or a mixture thereof, in combination with a stabilizing amount of a hindered amine light stabilizer of Markush formulae II or IIa. Also provided are masterbatch concentrates containing same, and processes for using same for stabilizing organic materials to protect against light and thermal degradation due to exposure to UV irradiation.
