ABSTRACT:
Compounds of the formula I ##STR1## in which x is 1, 2 or 3, and, if x=1, R.sup.1 is C.sub.1 -C.sub.30 alkyl, C.sub.1 -C.sub.18 alkyl substituted by halogen, --COOR.sup.2, --CN, --NR.sup.3 R.sup.4 or by --CONR.sup.3 R.sup.4, C.sub.2 -C.sub.18 alkyl which is interrupted by --NR.sup.5 --, --O-- or --S--, C.sub.3 -C.sub.18 alkenyl, C.sub.5 -C.sub.12 cycloalkyl, phenyl-C.sub.1 -C.sub.4 alkyl, phenyl which is unsubstituted or substituted by C.sub.1 -C.sub.12 alkyl, halogen, phenyl-C.sub.1 -C.sub.4 alkyl and/or C.sub.1 -C.sub.4 alkoxy, or R.sub.1 is naphthyl, a radical of the formula ##STR2## R.sub.2, R.sub.3, R.sub.4 and R.sub.5, independently of one another, are hydrogen, C.sub.1 -C.sub.18 alkyl, C.sub.5 -C.sub.12 cycloalkyl or phenyl-C.sub.1 -C.sub.4 alkyl, R.sup.6 is hydrogen, methyl, allyl or benzyl, R.sup.7 is hydrogen or --OR.sup.9, R.sup.8 is hydrogen or methyl, R.sup.9 is hydrogen or C.sub.1 -C.sub.30 alkyl, R.sup.10 and R.sup.11, independently of one another, are hydrogen or C.sub.1 -C.sub.8 alkyl, and n is 3-6, with the proviso that R.sup.1 is not a phenyl radical which is substituted in both ortho-positions to the carbon atom bonded to the oxygen atom, if x=2, R.sup.1 is C.sub.2 -C.sub.18 alkylene, C.sub.2 -C.sub.18 alkylene which is interrupted by --NR.sup.5 --, --O-- or --S--, or is a ##STR3## radical, and, if x=3, R.sup.1 is C.sub.4 -C.sub.12 alkanetriyl or a ##STR4## group in which m is 1-4, are suitable as stabilisers for organic materials which are sensitive to thermal, oxidative and/or photoinduced degradation.
