Dyes containing phosphonic acid groups as reactive links to be bonded to cellulose hydroxyl groups have been recently introduced into commercial use. In this investigation, the stability of the dye-fiber bond in reactive dyeings of this type on cotton fabrics has been determined by measurement of the rate of hydrolysis in the pH-range 2.2-8.6 at 98°C. The results demonstrate that this class of reactive dyes has dye-fiber bond stabilities that are in the same range as those of the other major classes of reactive dyes investigated previously. The dye-fiber bond stabilities reflect the wet-fastness properties of these dyeings.
