摘要

A description is given of compounds of the formula I in which R 1 is C 1 -C 18 alkyl; C 5 -C 12 cycloalkyl; C 3 -C 6 alkenyl; phenyl; C 1 -C 18 alkyl which is substituted by phenyl, OH, C 1 -C 18 alkoxy, C 5 -C 12 cycloalkoxy, C 3 -C 18 alkenyloxy, halogen, -COOH, -COOR 4 , -O-CO-R 5 , -O-CO-O-R 6 , -CO-NH 2 , -CO-NHR 7 , -CO-N(R 7 )(R 8 ), CN, NH 2 , NHR 7 , -N(R 7 )(R 8 ), -NH-CO-R 5 , phenoxy, C 1 -C 18 alkyl-substituted phenoxy, phenyl-C 1 -C 4 alkoxy, C 6 -C 15 bicycloalkoxy, C 6 -C 15 bicyclo-alkylalkoxy, C 6 -C 15 bicycloalkenylalkoxy, or C 6 -C 15 tricycloalkoxy; C 5 -C 12 cycloalkyl which is substituted by OH, C 1 -C 4 alkyl, C 2 -C 6 alkenyl or -O-CO-R 5 ; glycidyl; -CO-R 9 or -SO 2 -R 10 ; or R 1 is C 3 -C 50 alkyl which is interrupted by one or more oxygen atoms and/or substituted by OH, phenoxy or C 7 -C 18 alkylphenoxy; or R 1 denotes the specific polymerizable radicals indicated in claim 1; R 2 is C 6 -C 18 alkyl; C 2 -C 6 alkenyl; phenyl; C 7 -C 11 phenylalkyl; COOR 4 ; CN; NH-CO-R 5 ; halogen; trifluoromethyl; -O-R 3 ; R 3 embraces the definitions given for R 1 ; the radicals R 11 independently of one another are H; C 1 -C 18 alkyl; C 3 -C 6 alkenyl; phenyl; C 7 -C 11 phenylalkyl; halogen or C 1 -C 18 alkoxy, and the remaining radicals embrace the definitions given in claim 1, at least one of the radicals R 1 , R 2 and R 11 containing 4 or more carbon atoms. The novel compounds are effective as stabilizers for organic material against the damaging effect of light, oxygen and heat; they are also suitable for use in skin or hair protection preparations.
