ABSTRACT:
Soluble and thermally stable benzotriazole UV absorbers typified by those of formula I ##STR1## where R.sub.1 is hydrogen or chloro, R.sub.2 is alkyl or --CH.sub.2 CH.sub.2 COOR.sub.4 where R.sub.4 is hydrogen, alkyl or alkyl substituted with hydroxyl, and R.sub.3 is .alpha.-cumyl, provide excellent light stability protection to electro coat, base coat or clear coat finishes. The new soluble, crystalline form of 2-(2-hydroxy-3-.alpha.-cumyl-5-tert-octylphenyl)-2H-benzotriazole is particularly effective.
