2-[2-Hydroxy-3,5-di-(.alpha.,.alpha.-dimethylbenzyl)phenyl]-2H-benzotriazol e exhibits outstanding efficacy in protecting organic substrates from light induced deterioration as well as good resistance to loss by volatilization or exudation during the high temperature processing of stabilized compositions. The combination of the benzotriazole UV absorber with a hindered amine light stabilizer is particularly efficacious in protecting thermoset and thermoplastic acrylic resin automotive finishes and enamels.
2-[2-羟基-3,5-双-(.alpha.,.alpha.-二甲基苯基)苯基]-2H-苯并三唑具有出色的功效,可以保护有机基质免受光引起的恶化,同时在稳定组合物的高温处理过程中具有良好的抗挥发或渗出性能。苯并三唑紫外线吸收剂与受阻胺类光稳定剂的组合特别适用于保护热固性和热塑性丙烯酸树脂汽车涂装和珐琅的表面。
