    Abstract: The novel water-soluble disazo dyestuffs consist of two monoazo dyestuff moieties each containing as diazo component an amine of the benzene or naphthalene series and as coupling component an amino-naphthol-mono- or disulfonic acid. The two moieties are bonded to each other via a triazine radical which carries a halogen atom, and is bound to the amino groups of the coupling components and the diazo components contain a fiber-reactive radical of the vinyl sulfone series. To produce the dyestuffs 2 mols of the diazo compound carrying the fiber-reactive radical of the vinyl sulfone series is coupled with 1 mol of a bivalent coupling component consisting of 2 radicals of the aminonaphthol bound to the triazine ring via the amino groups, or two monoazo dyestuffs each synthesized from the aforesaid diazo component and an aminonaphthol-disulfonic acid coupling component are reacted with a 1,3,5-trihalogeno-triazine. The metal-free dyestuffs can be transformed into the corresponding heavy metal complex dyestuffs, preferably copper, cobalt and chromium complex dyestuffs, by treatment with an agent donating a heavy metal cation. The novel dyestuffs are excellently suitable for dyeing and printing fiber material of natural and regenerated cellulose and natural, regenerated and synthetic polyamides. They are distinguished by clear shades, high tinctorial strength, a very good uptake from a long liquor and a good color-build up. The dyeings obtained therewith have a high fastness to processing and in use.

    Abstract: NEW WATER-SOLUBLE, YELLOW REACTIVE DYES? PROCESS FOR THEIR PREPARATION AND THEIR UTILIZATION of the disclosure: Compounds which, in the form of the free acid, correspond to the general formula (1) in which A,A', B and B' each represent radicals of the benzene-, naphthalen- or heterocyclic series which may be identical or different, D and D' each represent a bivalent bridge member, which may be identical or different, X stands for a group which is linked to A, A', B and/or B' and corresponds to the formula -SO2-CH2-CH2-Y or -SO2-CH=CH2 in which Y stands for a radical which can be split off by alkaline agents or for a hydroxyl group, m and m1 is zero or the integer 0 to 1, the sum of m + m1 being at least 1, n and n1 each is zero or represent the integer 1, the sum of n + n1 being at least 1, p represents the integer 1 or 2, q represents the integer 1, 2 or 3, with the proviso that if the radical (B-Dn)m-A- represents the group A' represents a naphthalene nucleus, which are very well suitable for dyeing and printing of various fibre materials such as, for example, wool, silk, leather, polyamide or polyurethane fibres, but especially cellulose containing fibre materials such as cotton, regenerated cellulosic fibres and linen. The dyestuffs are preferably employed in accordance with the dyeing and printing processes for reactive dyestuffs which are generally customary in industry and yield on cellulose fibre materials, in the presence of acid binding agents, bright clear, yellow to very brilliant greenish yellow dyeings and prints of high tinctorial strength and a very good color build-up; they are very stable against washing and influence of light. Furthermore they have remarkably good fastnesses to water, sea-water, chlorinated bathing water, chlorine bleaching, fulling, rubbing, ironing, acid, alkalis and solvents. - 1a
