    Abstract: Monoazo dyestuffs which in the form of the free acid correspond to the general formula

    WHEREIN R1 is hydrogen or alkyl; R2 is hydrogen, halogen, alkyl, alkoxy, nitro, nitrile, carbonamide or carboxylic acid ester; R3 is hydrogen, halogen, alkyl or alkoxy; R4 is alkyl or aryl; R5 is hydrogen or alkyl, R6 is hydrogen, halogen or alkyl; R7 is hydrogen, halogen, alkyl, alkoxy or nitrile; X is C2-C4-alkylene, aralkylene or phenylene; Y is SO3H or, if X is phenylene, SO3H or a radical -SO2-NH-SO2-R8; and R8 is alkyl, aryl or dialkylamine. These dyestuffs are used for the dyeing of natural and synthetic fibre materials, especially for dyeing polyamide fibres. They yield level yellow to orange dyeings with very good fastness to light. Dyestuffs are absorbed well on polyamide fibres even in a neutral to weakly acid dyebath. The dyestuffs are employed in the form of the free acid or in the form of its salts, especially the alkali salts, such as the sodium or potassium salts or the ammonium salts.

    Abstract translation: 游离酸形式的单偶氮染料对应于通式，其中R1是氢或烷基; R2是氢，卤素，烷基，烷氧基，硝基，腈，碳酰胺或羧酸酯; R3是氢，卤素，烷基或烷氧基; R4是烷基或芳基; R5是氢或烷基，R6是氢，卤素或烷基; R7是氢，卤素，烷基，烷氧基或腈; X是C 2 -C 4亚烷基，亚芳基或亚苯基; Y是SO 3 H，或者如果X是亚苯基，则SO 3 H或-SO 2 -NH-SO 2 -R 8基团; R8是烷基，芳基或二烷基胺。 这些染料用于天然和合成纤维材料的染色，特别是染色聚酰胺纤维。 它们产生黄色至橙色的染色，具有非常好的耐光牢度。 即使在中性至弱酸性染浴中，染料也能很好的吸收在聚酰胺纤维上。 染料以游离酸的形式或其盐形式使用，特别是碱金属盐，例如钠盐或钾盐或铵盐。
