Abstract
Abstract The invention relates to compounds of the general formula I ##STR1## wherein R 1 and R 2 independently of one another are C 1 -C 8 -alkyl, C 5 -C 8 -cycloalkyl or C 7 -C 9 -aralkyl, R 3 is --CN or a group either of the formula II or III --(c.sub.n H.sub.2n)--COOR.sub.4 (II) or --[(C.sub.n H.sub.2n)--COO].sub.q M.sup.q+ (III) wherein n is 0 to 6, R 4 is C 1 -C 24 -alkyl, phenyl, or alkyl-substituted phenyl having 1-12 C atoms in the alkyl moiety, Q is 1, 2 or 3, M q+ is H + or a mono-, bi- or trivalent metallic cation, and X 1 and X 2 are --O-- or --S--, which are suitable as antioxidants and light stabilizers for organic material.
