| description | This invention relates to a class of water-soluble acid azo dyes, containing at least a sulphonic group, having formula (I): (I) wherein the symbols have the following meanings: A is a residue of a diazotizable aromatic or heterocyclic amine, optionally substituted; R is selected from the group consisting of H, CH3, OCH3 and OC2H5; R1 is selected from the group consisting of CH3 and C2H5; R2 is selected from the group consisting of CH3 and C2H5. The dyes which are the object of the present invention exhibit shades varying from yellow to blue and are useful for dyeing and printing natural polyamide fibres (wool and silk) and synthetic fibres (nylon). They possess an excellent affinity in both an acid bath and a neutral bath and an excellent tinting power. The dyes obtained are characterized by a remarkable purity of shade, by an excellent stability to sunlight, to washing and to sweat, as well as by a good equalizing power on nylon. |
