ABSTRACT:
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.
