摘要： Benzotriazole UV absorbers which are substituted at the 5-position of the benzo ring by an electron withdrawing group exhibit enhanced durability and very low loss rates when incorporated into automotive coatings. This is particularly the case when the 3-position of the phenyl ring is also substituted by phenyl or phenylalkyl such as &agr;-cumyl. Compounds where the 5-position of the benzo ring are substituted by perfluoroalkyl such as trifluoromethyl are particularly of interest for both their enhanced durability and for their excellent solubility and excellent color properties in some thermoplastic compositions when the phenyl ring is substituted at the 3-position by hydrogen or tert-alkyl.

摘要： Compounds of formula I or II where R is a heteroaryl moiety, such as 3-pyridyl, or T is a heteroaryl moiety, such as thien-2,5-diyl, and E1 and E2 are independently hydrogen, alkyl, aralkyl and the like, are prepared by reaction of a benzotriazole substituted on the 5-position of the benzo ring by a halogen atom with a heteroarylboronic acid or ester in the presence of a transition-metal catalyst, such as palladium (II) diacetate. The benzotriazole compounds of formula I are particularly efficacious as stabilizers for automotive coatings and candle wax.

摘要： Compounds which have a benzotriazole and a hindered amine moiety in the same molecule are typified by the formula A wherein at least one of G2, R1 or R2 contains a hindered amine moiety are extremely effective light stabilizers having both the UV absorbing activity of a benzotriazole and the light stabilizing efficacy of a hindered amine in the same molecule. These compounds are effective stabilizers for thermoset resin compositions, thermoplastic resin compositions, for photographic applications, for pigmented or dyed polypropylene, polyamide or polyester fibers, and for white, dyed, dipped, unscented and/or scented candle wax against discoloration and fading when incorporated therein alone or in combination with an antioxidant.
