  • Patent number: 5922865
    Abstract: Process for dyeing natural or synthetic polyamide fibre materials, which comprises dyeing these fibre materials with at least one anionic acid dye of the formula ##STR1## and treating the fibre material mentioned, during or after the dyeing process, with a colourless fixing agent which contains sulfo or sulfato groups and contains at least two fibre-reactive groups, whereR.sub.1 and R.sub.2 independently of one another are hydrogen or substituted or unsubstituted C.sub.1 -C.sub.4 alkyl,X.sub.1 is substituted or unsubstituted C.sub.1 -C.sub.8 alkyl, C.sub.5 -C.sub.7 cycloalkyl, phenyl or naphthyl,or the radical of the formula --N(R.sub.2)--X.sub.1 is a ring, which may contain further heteroatoms,Y.sub.1 is a radical of the formula ##STR2## in which B.sub.1 is a colourless organic bridge member,R.sub.3 is hydrogen or substituted or unsubstituted C.sub.1 -C.sub.4 alkyl andR.sub.4 is hydrogen or substituted or unsubstituted C.sub.1 -C.sub.8 alkyl, C.sub.5 -C.sub.7 cycloalkyl, phenyl or naphthyl, andA.sub.

  • Patent number: 5792222
    Abstract: Process for dyeing natural or synthetic polyamide fiber materials, which comprises dyeing these fiber materials with at least one anionic acid dye of the formula ##STR1## and treating the fiber material mentioned, during or after the dyeing process, with a colorless fixing agent which contains sulfo or sulfato groups and contains at least two fiber-reactive groups, whereR.sub.1 and R.sub.2 independently of one another are hydrogen or substituted or unsubstituted C.sub.1 -C.sub.4 alkyl,X.sub.1 is substituted or unsubstituted C.sub.1 -C.sub.8 alkyl, C.sub.5 -C.sub.7 cycloalkyl, phenyl or naphthyl, or the radical of the formula --N(R.sub.2)--X.sub.1 is a ring, which may contain further heteroatoms,Y.sub.1 is a radical of the formula ##STR2## in which B.sub.1 is a colorless organic bridge member,R.sub.3 is hydrogen or substituted or unsubstituted C.sub.1 -C.sub.4 alkyl andR.sub.4 is hydrogen or substituted or unsubstituted C.sub.1 -C.sub.8 alkyl, C.sub.5 -C.sub.7 cycloalkyl, phenyl or naphthyl, andA.sub.

  • Patent number: 5599354
    Abstract: The invention relates to dye mixtures consisting of(a) 0-100% by weight of at least one dye mixture comprising a compound of the formula ##STR1## and a compound of the formula ##STR2## (b) 0-100% by weight of at least one dye mixture comprising a compound of the formula ##STR3## and a compound of the formula ##STR4## in which the variables are as defined in the claims and the sum of (a) and (b) is 100% by weight. The dye mixtures according to the invention are suitable for dyeing or printing hydroxyl-containing or nitrogen-containing fibre materials and give dyeings or prints having good all-round fastness properties.
