摘要

Disclosed is the use of the compounds of formula wherein A is a radical of formula R₁ and R₅ independently from each other are hydrogen; C₁-C₁₈alkyl; or C₆-C₁₂aryl; R₂, R₃ and R₄ independently from each other are hydrogen; or a radical of formula wherein, in formula (1a), at least one of the radicals R₂, R₃ and R₄ are a radical of formula (1c); R₆, R₇, R₈, R₉ and R₁₀ independently from each other are hydrogen; hydroxy; halogen; C₁-C₁₈alkyl; C₁-C₁₈alkoxy; C₆-C₁₂aryl; biphenylyl; C₆-C₁₂aryloxy; C₁-C₁₈alkylthio; carboxy; -COOM; C₁-C₁₈-alkylcarboxyl; aminocarbonyl; or mono- or di-C₁-C₁₈alkylamino; C₁-C₁₀acylamino; -COOH; M is an alkali metal ion; x is 1 or 2; and y is a number from 2 to 10; for the protection of human and animal hair and skin against the damaging effect of UV radiation. The compounds of formula (1) are high effective UV absorbers for cosmetic formulations aund can be-depending on their physical properties be used in micronized or soluble form.
