N,N,N-Tri((het)aryl-(hetero)alk(en)yl, (het)aryl-(hetero)alkynyl and (het)aryl-(hetero)cycloalk(en)yl)-amines (I), with a total of not less than 6 alkoxy and hydroxy substituents, and their salts are new. N,N,N-Tri((het)aryl-(hetero)alk(en)yl, (het)aryl-(hetero)alkynyl and (het)aryl-(hetero)cycloalk(en)yl)-amines of formula (I), with a total of not less than 6 alkoxy and hydroxy substituents, and their salts are new: N(A 1>R 1>)(A 2>R 2>)(A 3>R 3>) (I) A 1>, A 2>, A 3>alkylene, alkenylene, alkynylene, cycloalkylene or cycolalkenylene groups, which may have 1, 2 or 3 substituents selected from alkoxy, hydroxy and keto and/or carbon (C) atom(s) replaced by heteroatom(s) selected from nitrogen (N), oxygen (O) and sulfur (S); R 1>, R 2>, R 3>aryl or 5- or 6-membered unsaturated heterocyclyl with 1, 2 or 3 N, O or S heteroatoms. A 1>, A 2>, A 3>, R 1>, R 2> and R 3> groups contain a total of not less than 6 alkoxy and hydroxy substituents. An independent claim is also included for stabilized hydroxylamine solutions containing compound(s) (I) as stabilizer.
