    摘要: Dyestuffs of the formula: ##STR1## are described, wherein K denotes the radical of a coupling component KH which can belong to the benzene, naphthalene or heterocyclic series. The dyestuffs are prepared by one-sided coupling of tetrazotized 4,4'-diamino-2,2'-dimethyldiphenyl with 2-hydroxynaphthalene-8-sulphonic acid in an alkaline medium, and reaction of the intermediate stage with the coupling component KH. The dyestuffs are useful for dyeing natural and synthetic, especially nitrogen containing fibre, materials such as wool and polyamides, including poly-.epsilon.-caprolactam or condensation products of adipic acid and hexamethylene diamine.

    摘要: Disazo dyestuffs wherein two N,N-dialkyl-p-phenylazoaniline dyestuff radicals are linked to each other via an N-alkyl group of the formula

    WHEREIN D1 and D2 are each the residue of a diazo component of the benzene series; R1 and R2 are hydrogen, alkyl or substituted alkyl; C1, C2, D1 AND D2 EACH REPRESENT HYDROGEN, METHYL, ETHYL, METHOXY, ETHOXY, PHENYLTHIO OR PHENOXY; R3 and R4 are each alkylene of up to 3 carbon atoms,

    SUCH THAT WHERE R3 and R4 are each

    Z is

    WHERE R5 is p-tolyl, p-methylcarbonylaminophenyl, phenyl, or C1-C3 alkyl or Z is -X''-Z''-X''wherein X'' is -O- or -NH- and Z'' is

    AND WHERE R3 and R4 are not each

    OR

    ARE DISCLOSED. Such dyestuffs are suitable for dyeing and printing synthetic fibers.
