The invention relates to an ink jet ink or ink jet recording material comprising at least one sterically hindered N-hydroxylamine strong acid salt of the formula (I) wherein G1 and G2 are e.g. C1-C4alkyl, Z1 and Z2 are each methyl, or Z1 and Z2 together form a linking moiety such as, for example, 1- hydroxy-2,2,6,6-tetramethyl-4-hydroxypiperidinium chloride or bis(1-hydroxy- 2,2,6,6-tetramethylpiperidin-4-yl) sebacate dihydrochloride; X is an anion of a strong acid, or comprising at least one dialkyl N-hydroxylamine salt of the formula (R51,R52N-OH) .bullet. (HY), for example, chloride, bisulfate, sulfate, phosphate, nitrate, ascorbate, formate, acetate, benzoate, oxalate, citrate, a carboxylate of thylenediaminetetraacetic acid or of diethylene- triaminepentaacetic acid or polyacrylate salts of N,N-diethylhydroxylamine, N,N-bis(2-hydroxypropyl)hydroxylamine, N,N-bis(3-hydroxypropyl)hydroxylamine, N,N-dibenzyl-hydroxylamine or the N,N-di(alkyl)hydroxylamine produced by the direct oxidation of N,N-di(hydrogenated tallow)amine.
La présente invention a trait à une encre pour imprimante à jet d'encre ou un matériau d'enregistrement pour imprimante à jet d'encre comportant au moins un sel d'acide fort de N-hydroxylamine à encombrement stérique de formule (I), dans laquelle : G¿1? et G¿2? représentent, par exemple, alkyle en C¿1?-C¿4 ; ?Z¿1? et¿ ?Z¿2? représentent chacun méthyle, ou¿ ?Z¿1? et¿ ?Z¿2? ensemble forment un groupe fonctionnel de liaison tel que, par exemple, le chlorure de 1-hydroxy-2,2,6,6-tétraméthyl-4-hydroxypipéridinium ou le dichlorhydrate de sébacate de bis(1-hydroxy-2,2,6,6-tétraméthylpipéridin-4-yle) ; X est un anion d'un acide fort, ou comportant au moins un sel de N-hydroxylamine dialkyle de formule (R¿51?,R¿52?N-OH) (HY), par exemple, chlorure, bisulfate, sulfate, phosphate, nitrate, ascorbate, formate, acétate, benzoate, oxalate, citrate, un carboxylate d'acide diéthylène-triaminepenta-acétique ou des sels de polyacrylate de N,N-diéthylhydroxylamine, N,N-bis(2-hydroxypropyl)hydroxylamine, N,N-bis(3-hydroxypropyl)hydroxylamine, N,N-dibenzyl-hydroxylamine ou de N,N-di(alkyl)hydroxylamine produits par l'oxydation directe de N,N-diamine de suif hydrogéné.
