Abstract
Compounds of the formula I ##STR1## in which m is 0 or 1 and n is 1 or 2 and R, R.sup.1, R.sup.2, Z and X are as defined in claim 1, and also salts of these compounds, are valuable light stabilizers for organic materials, especially for polymers. The compounds of the formula I can be prepared from the corresponding 4-sec.-aminopiperidines by reaction with cyclic dicarboxylic acid anhydrides and appropriate further reactions.
