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 and p 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.
包含对热、氧化和/或光降解敏感的有机材料以及至少一种具有公式I的化合物的组合物
其中Z.sub.1和Z.sub.2彼此独立地为C.sub.1 -C.sub.18烷基,C.sub.5 -C.sub.8环烷基,苯基,苯基-C.sub.1 -C.sub.4烷基或(C.sub.1 -C.sub.4烷基)苯基,p为4至18之间的数字,但Z.sub.1和Z.sub.2不能同时是三级烷基基团。公式I的一些化合物是新颖的。公式I的化合物也可与公式VI和/或公式VII的化合物混合使用,其中n和基团R.sup.1,R .sup.1 '和A如权利要求14和15所定义。
