    Abstract: 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.

    Abstract translation: 其中A,R1,m和n具有在说明书中给出的含义的式“IMAGE”的偶氮染料。 该染料适用于染色含纤维素的材料,特别是可能是天然或再生的棉,以及含有棉花和纸的联合织物。 染料一般给红色到紫色,以及红棕色的色调。 染料具有良好的耐光性,亲和性和耐湿性。 它们对于高温染色工艺的极大适应性和随后的抗皱整理值得特别提及。
