The present invention relates to an ink jet ink, an ink jet recording
material or an ink jet system comprising at least one sterically hindered
N-hydroxylamine strong acid salt, for example 1-hydroxy-2,2,6,6-tetrameth-
yl-4-hydroxypiperidinium chloride or bis(1-hydroxy-2,2,6,6-tetramethylpipe-
ridin-4-yl) sebacate dihydrochloride; or comprising at least one dialkyl
N-hydroxylamine salt, for example chloride, bisulfate, sulfate,
phosphate, nitrate, ascorbate, formate, acetate, benzoate, oxalate,
citrate, a carboxylate of ethylenediaminetetraacetic acid or of
diethylenetriaminepentaacetic acid or polyacrylate salts of
N,N-diethylhydroxylamine, N,N-bis(2-hydroxypropyl)hydroxylamine,
N,N-bis(3-hydroxypropyl)hydroxylamine, N,N-dibenzylhydroxylamine or the
N,N-di(alkyl)hydroxylamine produced by the direct oxidation of
N,N-di(hydrogenated tallow)amine.
