Benzotriazoles containing alpha-cumyl groups substituted by heteroatoms and compositions stabilized therewith

摘要

2H-Benzotriazole UV absorbers substituted at the 3-position and/or the 5-position of the phenyl ring by a phenyl moiety which is substituted by a heteroatom are particularly photostable in automotive coatings, and are of low color and exhibit low volatility in thermoplastic compositions.
