Compounds of the formula ##STR1## in which R.sub.1 is hydrogen or an aliphatic or aromatic substituent conventional for diazo component radicals of disperse dyes and which is bound to a N-atom in the 1- or 2-position of the triazole nucleus through a carbon atom, with the proviso that when R.sub.1 is in the 1-position, the broken line represents double bonds in the 2,3- and 4,5-positions and when R.sub.1 is in the 2-position, the broken line represents double bonds in the 3,4- and 1,5-positions, R.sub.2 is an electron withdrawing or inductive group, and K is a coupling component radical of the aniline series, with the proviso that the molecule is free from cationic groups, sulphonic acid groups, metals and metallizable groups, which compounds are useful as disperse dyes for textile substrates consisting of or comprising synthetic or semi-synthetic, hydrophobic, high molecular weight organic materials such as linear aromatic polyesters, cellulose 21/2 acetate, cellulose triacetate and synthetic polyamides.
化学式为##STR1##的化合物,其中R.sub.1是氢或传统用于分散染料的重氮组分基团的脂肪族或芳香族取代基,通过碳原子与1-或2-位置的三唑环中的N原子结合,但当R.sub.1在1-位置时,断裂的线表示2,3-和4,5-位置的双键,当R.sub.1在2-位置时,断裂的线表示3,4-和1,5-位置的双键,R.sub.2是一个电子吸引或归纳基团,K是苯胺系列的偶联组分基团,但分子不含阳离子基团、磺酸基团、金属和可金属化基团。这些化合物可用作分散染料,用于由合成或半合成、亲水性、高分子量有机材料制成或包含的纺织物基材,如线性芳香族聚酯、纤维素21/2醋酸酯、纤维素三醋酸酯和合成聚酰胺。
