    摘要： Compositions comprising an organic material which is sensitive to thermal, oxidative and/or actinic degradation and at least one compound of the formula I ##STR1## in which Z.sub.1 and Z.sub.2 independently of one another are C.sub.1 -C.sub.18 alkyl, C.sub.5 -C.sub.8 cycloalkyl, phenyl, phenyl-C.sub.1 -C.sub.4 alkyl or (C.sub.1 -C.sub.4 alkyl)phenyl andp is a number from 4 to 18,with the proviso that Z.sub.1 and Z.sub.2 are not simultaneously tertiary alkyl radicals. Some of the compounds of the formula I are novel.The compounds of the formula I can also be employed as stabilizers as a mixture with compounds of the formula VI and/or of the formula VII ##STR2## in which n and the radicals R.sup.1, R .sup.1 ' and A are as defined in claims 14 and 15.
