    摘要： Basic sulpho group-containing disazo compounds which are metal-free, correspond to the formula ##STR1## in which the symbols are as defined in claim 1. These compounds, in form of their water-soluble salts, and preparations thereof are used for dyeing or printing cationically dyeable materials such as hydroxy group- or nitrogen-containing organic substrates of which textile material comprising natural or synthetic polyamide or natural or regenerated cellulose and especially cotton, leather and paper are preferred. Furthermore, they can be used for the preparation of inks in a conventional manner.

    摘要： 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.

    摘要： Compounds which in the form of the free acid correspond to the formula

    WHEREIN R1, R2, n1, n2 and n3 have the meaning given in the description. The new dyestuffs dye vegetable and animal fibre materials and are particularly well suited for dyeing and printing of leather. They show good fastness properties, such as e.g., resistance to acid, resistance to alkalies, resistance to formaldehyde, resistance to solvents, resistance to fatliquoring, or dyeability in hard water; in particular the good fastness to light of the dyestuffs is to be stressed.
