ABSTRACT:
Compounds of the formula I ##STR1## wherein R.sub.1 is hydrogen, C.sub.1 -C.sub.18 alkyl, C.sub.5 -C.sub.12 cycloalkyl, phenyl or C.sub.7 -C.sub.9 phenylalkyl and R.sub.2 is hydrogen or C.sub.1 -C.sub.18 alkyl, or, if R.sub.1 is hydrogen, R.sub.2 is a divalent 1,1,3,3,-tetramethylpropylene radical fused in the 2-position and 3-position or the 9-position and 10-position, and X is sulfur or a group --CH(R).sub.3 --, in which R.sub.3 is hydrogen or a radical of the formula II --CH(R.sub.4)--CH(R.sub.5)SR.sub.6, and each of R.sub.4 and R.sub.5 independently is hydrogen or C.sub.1 -C.sub.6 alkyl and R.sub.6 is C.sub.1 -C.sub.20 alkyl, while the alkyl group can be interrupted by one or more sulfur atoms, and A is a primary or secondary aliphatic or alicyclic, aromatic or araliphatic amine which contains substituents of the same type or mixed substituents, or a heterocyclic amine or a hydrazine derivative. These compounds are useful stabilizers for organic material.
