ABSTRACT:
The invention relates to the use of enaminotriazines of the formula Iin which the radicals Y, independently of one another, are hydrogen, an optionally substituted aliphatic, cycloaliphatic, araliphatic or aromatic radical having in each case up to 18 carbon atoms, the radicals X are identical or different, where at least one of the radicals X is the ethenyl radical of the formula IIand X may also have the meanings of Y, and where in the formula II the radicals R are identical or different and are cyano, optionally esterified carboxyl, substituted carbonyl, optionally substituted aminocarbonyl, optionally esterified sulfo, substituted sulfonyl or optionally esterified phosphono, and where two adjacent radicals R may optionally form a ring and the radicals R′ are identical or different and are hydrogen, an optionally substituted aliphatic, cycloaliphatic or aromatic radical having in each case up to 18 carbon atoms, as UV filters in cosmetic or pharmaceutical preparations for protecting human skin or human hair against solar rays, alone or together with compounds which absorb in the UV region and which are known per se for cosmetic preparations.
