    摘要： The present invention relates to a process for the differential dyeing of such polyamide fibres and materials containing polyamide fibres as are made of components which differ in dyeability, or mixtures of polyamide fibres, with dyes or dye mixtures, which comprises using for dyeing these materials an aqueous liquor which contains a dye of the formula ##STR1## in which A.sub.1 is hydrogen or C.sub.1-4 alkyl and R is a C.sub.2-5 -alkanoyl, C.sub.3-6 -alkenoyl, (C.sub.1-4 -alkoxy)carbonyl, phenoxycarbonyl, C.sub.1-4 -alkylsulfonyl or phenylsulfonyl radical which can be substituted in the alkyl, alkenyl, alkoxy, phenoxy or phenyl moiety, or a mixture of a dye of the formula (1) with a monosulfo-containing anthraquinone dye, and to those dyes of the formula (1) in which A.sub.1 is as defined above and R is a C.sub.1-4 -alkylsulfonyl or phenylsulfonyl radical which can be substituted in the phenyl moiety by C.sub.1-4 -alkyl.Even at low dyeing temperatures, the process of the invention gives ombre effects rich in contrast and, on admixture of other suitable acid dyes, multicolor effects on polyamide fibres which are suitable for differential dyeing.

    摘要： A process for dyeing textile planar fabrics made from natural or synthetic polyamides with anionic dyes by(a) locally applying a resist agent by itself or in conjunction with an anionic dye of fluorescent whitening agent,(b) subjecting the textiles to a heat treatment, and(c) carrying out ground dyeing with a dye liquor that contains a further anionic dye,which process comprises using, as resist agent, a melamine compound of formula ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 are each independently phenyl or naphthyl, each of which may be substituted by halogen, hydroxy, C.sub.1 -C.sub.3 alkyl or C.sub.1 -C.sub.3 alkoxy, Z is an acid water-solubilizing group, and m is 1 to 6.
