Document Type and Number:
Japanese Patent JP2519426
Kind Code:
B2
Abstract:
5-tert-Octyl-2-(2-hydroxy-3,5-di-alpha-cumylphenyl)-2H-benzotriazole and related 2H-benzotriazoles substituted on the 5-position of the benzo ring by a higher alkyl group such as tert-octyl or dodecyl exhibit 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 above-named compounds exhibit good solubility in common organic solvents, and exhibit very high extinction coefficients.
