ABSTRACT:
Compounds of the formula (1), ##STR1## in which R.sub.1 is C.sub.1 -C.sub.25 alkyl, C.sub.7 -C.sub.9 phenylalkyl, unsubstituted or C.sub.1 -C.sub.4 alkyl-substituted phenyl, unsubstituted or C.sub.1 -C.sub.4 alkyl-substituted C.sub.5 -C.sub.8 cycloalkyl; C.sub.3 -C.sub.25 alkenyl, C.sub.3 -C.sub.25 alkynyl or C.sub.3 -C.sub.25 alkyl which is interrupted by oxygen, sulfur or >N--R.sub.16, and R.sub.16 is hydrogen or C.sub.1 -C.sub.8 alkyl, R.sub.2, R.sub.3, R.sub.4 and R.sub.5, independently of one another are hydrogen, C.sub.1 -C.sub.25 alkyl, C.sub.7 -C.sub.9 phenylalkyl, unsubstituted or C.sub.1 -C.sub.4 alkyl-substituted phenyl, unsubstituted or C.sub.1 -C.sub.4 alkyl-substituted C.sub.5 -C.sub.8 cycloalkyl; C.sub.1 -C.sub.18 alkoxy, hydroxyl, C.sub.1 -C.sub.25 alkanoyloxy, C.sub.3 -C.sub.25 alkenoyloxy, C.sub.3 -C.sub.25 alkanoyloxy which is interrupted by oxygen, sulfur or >N--R.sub.16 ; C.sub.6 -C.sub.9 cycloalkylcarbonyloxy, benzoyloxy or benzoyloxy which is substituted by C.sub.1 -C.sub.12 alkyl, and R.sub.16 is as defined above, or, furthermore, the radicals R.sub.2 and R.sub.3 or the radicals R.sub.4 and R.sub.5 together with the carbon atoms to which they are bound form a benzo ring, R.sub.4 is additionally --(CH.sub.2).sub.n --COR.sub.11, in which n is 0, 1 or 2, R.sub.11 is hydroxyl, ##EQU1## C.sub.1 -C.sub.18 alkoxy or ##STR2## R.sub.14 and R.sub.15, independently of one another are hydrogen or C.sub.1 -C.sub.18 alkyl, M is an r-valent metal cation and r is 1, 2 or 3, R.sub.7, R.sub.8, R.sub.9 and R.sub.10, independently of one another, are hydrogen, C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.4 alkoxy, with the proviso that at least one of the radicals R.sub.7, R.sub.8, R.sub.9 R.sub.10 is hydrogen, and, in the case where R.sub.3, R.sub.5, R.sub.6, R.sub.7 and R.sub.10 are hydrogen, R.sub.4 is additionally a radical of the formula (2) ##STR3## in which R.sub.1, R.sub.2, R.sub.8 and R.sub.9 are as defined above and R.sub.12 and R.sub.13, independently of one another, are hydrogen, CF.sub.3, C.sub.1 -C.sub.12 alkyl or phenyl, or R.sub.12 and R.sub.13 together with the carbon atom to which they are bound form a C.sub.5 -C.sub.8 cycloalkylidene ring which is unsubstituted or substituted by 1 to 3 C.sub.1 -C.sub.4 alkyl; R.sub.6 is hydrogen or a radical of the formula (3) ##STR4## in which R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.7, R.sub.8, R.sub.9 and R.sub.10 are as defined above, are described as stabilizers for organic materials against thermal, oxidative or light-induced degradation.
