ABSTRACT:
The present invention relates to an ink jet ink, an ink jet recording material or an ink jet system comprising at least one compound selected from the group consisting of a) the dialkyl hydroxylamine stabilizers, b) the nitrone stabilizers and c) the amine oxide stabilizers. The present stabilizer compounds provide ink jet prints with outstanding light stability, gas fade stability and dark storage stability. The hydroxylamines are for example N,N-dihydrocarbylhydroxylamines of the formula R1R2N—OH, wherein R1and R2are independently benzyl, methyl, ethyl, octyl, lauryl, dodecyl, tetradecyl, hexadecyl, heptadecyl or octadecyl, or wherein R1and R2are each the alkyl mixture found in hydrogenated tallow amine. The nitrone and amine oxide stabilizers are for example nitrone and amine oxide analogues of the dialkylhydroxylamine stabilizers.
