Abstract:
A process for dyeing or printing fiber materials containing hydroxy and/or carbonamide groups, in which process a fiber-reactive, water-soluble dyestuff of the type defined below is applied to the fiber material and is then fixed on the fiber material at an ordinary or elevated temperature, if appropriate in the presence of agents having an alkaline reaction. This water-soluble dyestuff, which contains at least one sulfonic acid group, contains one or more groupings belonging to the group comprising the formulae (1a), (1b) and (1c)--SO.sub.2 --CH.dbd.CH.sub.2 (1a)--SO.sub.2 --CH.sub.2 --CH.sub.2 --Hal (1b)--SO.sub.2 --CH.sub.2 --CH.sub.2 --A (1c)(in which Hal represents a halogen atom and A represents the acyloxy radical of a monobasic or polybasic acid) and also contains, linked to it, a 6-fluoro-1,3,5-triazin-2-ylamino radical, this monofluorotriazinylamino radical containing, in the 4-position, a substituent which is not an N-phenylamino or N-naphthylamino substituent having a group belonging to the above-mentioned formulae (1) attached to the optionally substituted phenyl radical or optionally substituted naphthyl radical, and is also not an amino substituent containing an azo group. Dyestuffs of this type can belong to a very wide variety of classes of dyestuffs and can be both metal-free dyestuffs and metal complex dyestuffs. With the aid of these dyestuffs and using alkaline agents, this dyeing process produces deep dyeings and prints which have good fastness properties on these fiber materials, even at low temperatures.
Abstract:
Water-soluble fibre-reactive dyestuffs containing one or two fibre-reactive groups of the vinylsulfone series and one or two fibre-reactive groups of the fluoro-s-triazinyl-amino series. These dyestuffs can be applied on fibre materials containing hydroxy and/or carbonamide groups by known application and fixation techniques for fibre-reactive dyes to yield deep and fast dyeings on these materials.
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.
