    Abstract: Dyes of the formula ##STR1## where X and Y, for example, can be hydrogen or halogen and R can be alkyl among other substituents. The dyes are derived from an O-nitroaniline diazo component and an N-substituted homophthalimide as coupling component. The dyes are greenish yellow to orange and give clear dyeings of good color strength and having good general fastness properties on polyesters, cellulose esters and in some cases also on polyamides. The fastness to light and the fastness to heat setting are excellent and may easily be influenced by the choice of substituents.

    Abstract translation: 其中X和Y例如可以是氢或卤素,R可以是其它取代基中的烷基。 染料衍生自O-硝基苯胺重氮组分和N-取代的高邻苯二甲酰亚胺作为偶联组分。 染料是绿黄色至橙色,并且具有良好着色强度的清晰染色,并且在聚酯,纤维素酯上以及在某些情况下也在聚酰胺上具有良好的通用牢度性能。 耐光牢度和耐热牢固度是优异的,并且可容易地受到取代基的选择的影响。

    Abstract: Disazo dyestuff which in the form of the free acid correspond to the formula ##STR1## in which W stands for the radical ##STR2## or the radical ##STR3## R.sub.1 stands for hydrogen, an alkyl radical or a phenyl group; R.sub.2 and R.sub.3, independently of one another, stand for hydrogen, halogen, an alkyl group, an alkoxy group or an acylamino group; R.sub.4 stands for hydrogen, halogen, an alkyl group, an alkoxy group or an acylamino group; R.sub.5 stands for hydrogen, an alkyl group or an alkoxy group; R.sub.6 and R.sub.7, independently of one another, stand for hydrogen, hydroxy, cyano, halogen, acyloxy, alkoxycarbonyl or phenyl; X stands for an alkylene radical with 1 - 4 carbon atoms; R.sub.8 stands for an alkyl, phenyl, 2-naphthyl or 4-biphenyl group which is not further substituted; R.sub.9 stands for hydrogen or an alkyl group with 1 - 6 carbon atoms which may be substituted by a nitrile, carboxamide or carboxyl group; R.sub.10 stands for a substituent; and n stands for the numbers 0 - 2.This dyestuff is suitable for dyeing synthetic fibers, especially polyamide fibers, with very good fastness to light.
