The present invention provides liquid aqueous dyeing preparations of reactive dyestuffs which in the form of their free acid correspond to the formula (I) (HO3S)m-F-Zn (I) , wherein F represents the radical of a dyestuff chromophore of an anthraquinone, a mono-, dis- or tris-azo dyestuff, or of a phthalocyanine dyestuff, the phthalocyanine dyestuffs as well as the azo dyestuffs possibly being present as complex metal compounds with Cu, Cr, Co, Ni or Fe as the complex-forming central atom, m represents an integer being 2 or above, for example an integer in the range of from 2 to 8, and n is an integer in the range of from 1 to 3, and Z stands for a fiber-reactive group, said dyeing preparations being suitable for the dyeing and printing of fiber materials on the basis of wool, silk, polyamide and natural or regenerated cellulose, according to the process which is common for reactive dyestuffs. |
