ABSTRACT:
A compound of formula (I) ##STR1## in which R.sub.1 and R.sub.2 are e.g. hydrogen or methyl, R.sub.3 is e.g. a group ##STR2## or a group R.sub.5 X-- with R.sub.5 being e.g. hydrogen, C.sub.1 -C.sub.18 -alkyl or C.sub.3 -C.sub.18 -alkenyl and X being e.g. --O--, --S-- or ##STR3## and R.sub.6 is as defined for R.sub.5, or R.sub.3 represents a 5-membered to 7-membered nitrogen containing heterocyclic group with the free valency on the nitrogen, n is an integer from 2 to 6, and R.sub.4 is a nitrogen containing organic radical of a valency equal to n.
The compounds of formula (I) are particularly effective in stabilizing organic material against oxidative, thermal and/or light induced degradation.
