Compound process for its preparation stabilized composition against the deleterious effects of actinic radiation use of said compound and method to protect an organic polymer against the degradation caused by oxygen light and / or heat

摘要

Tris-aryl-s-triazines which contain from one to three resorcinol derived moieties with at least one of said moieties substituted at the 5-position with an alkyl, phenylalkyl, halogen, thio or sulfonyl group have UV spectra which are red-shifted to the near UV range and provide excellent stabilization to polymeric substrates against the deleterious effects of actinic light.
