    摘要： Disazo dyestuffs which in the form of the free acid correspond to the general formula ##STR1## wherein R denotes an alkyl radical with 1-4 carbon atoms, X represents hydrogen or a methyl group and Y represents hydrogen or an alkyl radical with 1-4 carbon atoms, and the ring A can be substituted by chlorine or alkyl groups with 1-4 C atoms.The dyestuffs are especially suitable for dyeing polyamide fibers from neutral to weakly acid dyebaths. The dyeings are of good light fastness.

    摘要： Azo dyestuffs of the formula ##STR1## wherein A, R.sub.1, m and n have the meaning given in the description. The dyestuffs are suitable for dyeing cellulose-containing materials, especially cotton, which may be natural or regenerated, as well as union fabrics containing cotton, and paper. The dyestuffs in general give red to violet, as well as reddish brown, color shades.The dyestuffs are distinguished by good light-fastness, substantivity and wet-fastness. Their great suitability for high temperature dyeing processes and for subsequent creaseproof finishing deserves particular mention.
