Abstract
A compound of the formula I ##STR1## in which R.sub.2 is an optionally substituted 4-piperidinyl bonded via oxy or imino, or an optionally substituted 2-(piperidino)-ethoxy, n is 1 or 2, R.sub.7 and R.sub.8 are hydrocarbon radicals, R.sub.9 is hydrogen or methyl, R.sub.14 is cyano, --CH.sub.2 OH, a hydroxymethyl which is C-substituted by an optionally substituted 4-piperidinyl bonded via oxy or imino, or by an optionally substituted 2-(piperidino)-ethoxy, or R.sub.14 is also acyl or nitro, and, when n=1, R.sub.15 is hydrogen, a substituted hydroxybenzyl, an optionally substituted hydrocarbon radical, an optionally substituted 4-piperidinyl, or alkylene which is optionally linked to R.sub.14 and optionally substituted, or, when n=2, R.sub.15 is a direct bond or an optionally interrupted hydrocarbon radical, and its salts as stabilizers for organic material.
