Abstract:
A compound of the formula (I) ##STR1## wherein n is an integer from 1 to 4; the radicals R.sub.1 are for example a group of the formula ##STR2## R.sub.3 is for example hydrogen, C.sub.1 -C.sub.8 alkyl or C.sub.5 -C.sub.12 cycloalkoxy; Z and R.sub.2 are for example a group ##STR3## the radicals A and E are, for example, independently of one another --N(R.sub.11)(R.sub.12) or a group of the formula ##STR4## R.sub.11 and R.sub.12 are for example C.sub.1 -C.sub.12 alkyl; R.sub.13 has for example one of the meanings given for R.sub.3 ; E* has for example one of the meanings given for A or is a group of the formula ##STR5## The compounds of the formula (I) are useful as light stabilizers, heat stabilizers and oxidation stabilizers for organic materials, in particular synthetic polymers such as polyolefins.
