<p>The colorants disclosed correspond to the formula (FORMULA) wherein D represents the residue of an organic colorant, which contains at least an aqua-solubilizing group, R represents an halogeno-alkyl residue having one or two atoms of carbon or else represent an halogeno-acryl residue and n represents an integer from 1 to 4; each group of the formula (FORMULA) being bound to an "aromatic" carbon atom of the residue D. These compounds are obtained by reaction of appropriate colorants of the formula D(Alpha)H)n with halogeno-acrylil-amido-glycolic acids or halogeno-alkanyl-amido-glycolic acids. The reactive colorants obtained are particularly appropriate for dyeing of cellulose and polyamidic material. </p> |
