A total of 110 arylazo dyes have been prepared, based on five benzenoid and heterocyclic coupling components, and containing combinations of chlorine and sulphonate (sulpho) substituents in the diazo components. Their visibleabsorptionmaxima have been analysed in order to determine the degree to which chloro and sulpho substituentinfluences are constant and transferable, both within a series, and

Water-soluble azo dyes which, in the form of the free acids, contain either one or two groups of the formula:
wherein Z represents an oxygen atom or a direct link and either one or two residues of the formula:
wherein X represents -S- or -NR1 and each of R and R' independently, denotes an alkyl radical which may carry a non-aromatic substituent.
These dyes are valuable for colouring polyamides giving yellow shades with good fastness to light and wet treatments.
水溶性偶氮染料,其游离酸形式含有一个或两个式中的基团:
其中 Z 代表氧原子或直接连接,以及一个或两个式中的残基:
其中 X 代表-S-或-NR1,R 和 R'各自独立地表示烷基,可带有非芳香族取代基。
这些染料可用于聚酰胺的着色,产生耐光性和耐湿性良好的黄色色调。
