摘要：Water-soluble disazo compounds, which can be ud as fiber reactive dyestuffs and correspond to the general formula ##STR1## in which Y is vinyl or --CH.sub.2 --CH.sub.2 --Z, Z being sulfato, phosphato, halogen or hydroxy;
d is phenylen
e or phenylene substituted by 1 or 2 radicals lected from the group consisting o
f lower alkyl, lower alkoxy, hydroxy, chlorine, bromine, fluorine, carboxy, nitro and sulfo, or
D is naphthylene or naphthylene substituted by 1 or 2 radicals lected from the group consisting of lower alkyl, lower alkoxy, hydroxy, chlorine, bromine, fluorine, carboxy and sulfo;
E is 1,4-phenylene or 1,4-naphthylene, or 1, 4-phenylene or 1,4- naphthylene substituted by 1 or 2 radicals lected from the group consisting of lower alkyl, lower alkoxy, hydroxy, ureido, lower alkanoylamino, chlorine, bromine, carboxy and sulfo;小学英语网>牡丹的诗词

R.sup.3 is hydrogen, lower alkyl, lower alkoxy or halogen.
The disazo compounds can be prepared in a manner which is in itlf known by reacting the diazo and coupling components which are evident from the formula (1). They rve as dyestuffs for dyeing and printing fibers which contain hydroxyl and/or cabonamide groups, such as cellulo fibers, wool
or synthetic polyamide fibers, or leathers.
