Esters or phenol ethers of the formula I or II ##STR1## in which m and n are each an integer from the range from 1 to 6; A.sup.1 is an m-valent hydrocarbon radical having 1 to 30 carbon atoms; or an m-valent hydrocarbon radical having 2 to 30 carbon atoms, which contains the heteroatoms oxygen, nitrogen and/or sulfur and the free valencies of which are located on carbon atoms and in which A.sup.1, in the case where m=2, additionally is a direct bond; A.sup.2 is an n-valent aromatic or araliphatic hydrocarbon radical having 6 to 30 carbon atoms; or an n-valent aromatic or araliphatic hydrocarbon radical having 5 to 30 carbon atoms, which contains the heteroatoms oxygen, nitrogen and/or sulfur and n free valencies of which are located on those carbon atoms which are a constituent of aromatic rings; R.sup.1 is hydrogen; a hydrocarbon or hydrocarbonoxy radical having 1 to 36 carbon atoms, which is unsubstituted or substituted by --CO--N(R.sup.3).sub.2 or interrupted by --CO--N(R.sup.3)-- or --N(R.sup.3)--CO-- or 1 to 6 oxygen or sulfur atoms; benzoyl or naphthoyl, each of which is substituted by 1 to 3 C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.4 alkoxy radicals; or --CO--R.sup.2 ; in which R.sup.2 is C.sub.1 -C.sub.18 alkyl; C.sub.5 -C.sub.8 cycloalkyl; phenyl; naphthyl; C.sub.7 -C.sub.9 phenylalkyl; or C.sub.11 -C.sub.14 naphthylalkyl; and R.sup.3 has the same meanings as R.sup.2 or is hydrogen, are described. The compounds are suitable for stabilizing organic material against the damaging influence of light, oxygen and/or heat.
