Abstract

Useful stabilizers for organic material, in particular plastics and paints, and metal ion deactivators are amides of the formula ##STR1## where R.sup.1 and R.sup.2 are singly methyl or together tetramethylene or pentamethylene, R.sup.3 is hydrogen, alkyl, alkoxycarbonyl, alkanoyl, benzyl, hydroxyethyl, cyanomethyl or aminomethyl, n is 1, 2 or 3 and--when n is 1--R.sup.4 is hydrogen and R.sup.5 is --CO--R.sup.6 is H, alkyl, cycloalkyl, aralkyl, phenoxyalkyl, aryl, a 5- or 6-membered heterocycle, alkoxy, aryloxy, cycloalkyloxy, phenylalkoxy, carbamoyl or --SO.sub.2 --R.sup.8 where R.sup.8 is alkyl or phenyl or ##STR2## is a phthalimide group or--when n is 2--R.sup.4 is H and R.sup.5 is --CO--Z--CO-- where Z is a chemical bond, C.sub.1 -C.sub.8 -alkylene, oxaalkylene, phenylene, cyclohexylene, biphenylene, biphenylene oxide, dioxyphenylene, diaminophenylene, diaminocyclohexylene, 1-.OMEGA.-diiminoalkylene or a 2-valent heterocycle or ##STR3## is a pyromellimide group or--when n is 3--R.sup.4 is H and R.sup.5 is ##STR4## where R.sup.10 is a trivalent alkyl or 3-valent aryl, or acid addition salts and hydrates thereof.
