    • The present invention discloses substituted phenyl di and trisazo dyes free of reactive groups having two or three sulfonic acid groups, of the general formula: ##STR1## wherein D.sup.1 is ##STR2## Z is hydrogen or D.sup.4 --N.dbd.N--; D.sup.2 is phenyl substituted by hydroxyl, hydroxysulfonyl, chlorine or nitro, or is naphthyl substituted by hydroxy, hydroxysulfonyl or nitro, X, independently of one another, are hydroxyl or amino, D.sup.3 is phenyl which is substituted by hydroxysulfonyl, chlorine, bromine, methyl, methoxy, ethoxy, nitro, phenylamino, sulfophenylamino or nitrosulfophenylamino, or is naphthyl which is substituted by hydroxysulfonyl; D.sup.4 is phenyl which is unsubstituted or substituted by methyl, ethyl, methoxy, ethoxy, chlorine, bromine, nitro, sulfamoyl or hydroxysulfonyl, or is naphthyl which is substituted by hydroxysulfonyl; and R.sup.2 is methyl, ethyl or allyl; the rings B and E may additionally be substituted by methyl, ethyl, methoxy, ethoxy, chlorine, bromine or hydroxysulfonyl, with the proviso that D.sup.2 has a hydroxyl group ortho to the azo bond; or the iron, manganese, cobalt, chromium, nickel or copper complexes of this dye. These compounds, particularly in the form of their metal complexes are suitable for dyeing nitrogen-containing fibers such as wool, and preferably, leather. The present dyes yield very fast brown hues, in particular on retanned leather.
    • 本发明公开了不具有两个或三个磺酸基团的反应性基团的取代苯基二和三偶氮染料,其通式如下:其中D1是氢或D4-N = N-; D2是由羟基,羟基磺酰基,氯或硝基取代的苯基,或被羟基,羟基磺酰基或硝基取代的萘基,X彼此独立地是羟基或氨基,D3是被羟基磺酰基,氯,溴,甲基 ,甲氧基,乙氧基,硝基,苯基氨基,磺基苯基氨基或亚硝基磺基苯基氨基,或被被羟基磺酰基取代的萘基; D4是未取代或被甲基,乙基,甲氧基,乙氧基,氯,溴,硝基,氨磺酰基或羟基磺酰基取代的苯基,或被羟基磺酰基取代的萘基; 和R2是甲基,乙基或烯丙基; 环B和E可以另外被甲基,乙基,甲氧基,乙氧基,氯,溴或羟基磺酰基取代,条件是D2具有与偶氮键邻位的羟基; 或该染料的铁,锰,钴,铬,镍或铜络合物。 这些化合物,特别是其金属络合物的形式,适用于染色含氮纤维如羊毛,优选皮革。 本染料产生非常快的棕色色调,特别是在鞣革上。
