Abstract

Organic materials which possess outstanding stability to oxidative, thermal or light-induced degradation comprise as stabilizers at least one compound of the formula (I) wherein the general symbols are as defined in claim 1. The compounds of formula I are especially useful as stabilizers for protecting polymers and lubricants against oxidative, thermal or light-induced degradation and as scavengers for oxidized developer in color photographic material.
