Abstract:
Metal complexes of disazo dyestuffs of the formula ##STR1## wherein one X=chlorine and the other X=NO.sub.2, or both the radicals X=chlorine, and R=the radical of a diazo component of the benzene, naphthalene or diphenylamine series which, in the o-position relative to the azo group, is free from groups which form metal complexes, and their use for dyeing and printing of nitrogen containing materials, such as silk, wool or synthetic fibers of polyamides or polyurethanes. The resulting dyeings have excellent fastness properties.
Abstract translation:其中一个X =氯,另一个X = NO 2,或两者基团X =氯,R =苯,萘或二苯胺系列的重氮组分的基团, 在相对于偶氮基的o位置,不含形成金属络合物的基团,以及它们用于染色和印刷含氮材料如丝,羊毛或聚酰胺或聚氨酯合成纤维的用途。 所得染色具有优异的牢度性能。
Abstract:
Iron complexes of azo dyestuffs of the formula ##STR1## wherein R.sub.1 and R.sub.2 have the meaning indicated in the description,and their use for dyeing or printing various fibre materials, for example wool, silk and synthetic materials such as Perlon, but especially leather. The dyeings obtained are distinguished by good fastness properties.
Abstract:
The subject matter of the present invention relates to tetrakisazo dyestuffs which in the acid form correspond to the formula ##STR1## wherein R = H or substituent,R.sub.1 = h or SO.sub.3 HZ.sub.1, z.sub.2 = an optionally substituted amino group,n = 1 or 2m = 1 or 2, n + m being .ltoreq.3 and wherein the rings A and B may have further substituents, for example, alkoxy groups such as methoxy groups.The new dyestuffs are suitable for the dyeing and printing of natural fibre materials, especially leather, and distinguish themselves by good fastness properties.

Abstract:
The subject matter of the present invention relates to tetrakisazo dyestuffs which in the acid form correspond to the formula ##STR1##wherein Z.sub.1, Z.sub.2 = an optionally substituted amino groupR = h or a non-ionogenic substituent, in particular halogen or alkyl,n = an integer of 1 to 3The rings A and B possible having further substituents, for example, alkoxy groups, such as methoxy groups, and the substituents R as well as Z.sub.1 and Z.sub.2 being the same or different. The new dyestuffs are suitable for dyeing and printing of natural fiber materials and distinguish themselves by good fastness properties.
