    摘要： Water-soluble reactive azo dyestuffs of the formula (1)

    WHEREIN R represents a hydrogen atom or a lower alkyl radical a cyclohexyl radical or a phenyl radical, Q represents a hydrogen atom or a hydroxyl group and Z stands for one of the groupings (2a), (2b) or (2c) -CH2-CH2-OSO3H(2a) -CH CH2(2b) -CH2-CH2OH(2c) AND N STANDS FOR THE INTEGER 1 OR 2, WHICH ARE VERY SUITABLE FOR DYEING AND PRINTING MATERIALS MADE OF NATURAL CELLULOSE FIBERS, PARTICULARLY COTTON, REGENERATED CELLULOSE FIBERS, LINEN, SILK, POLYAMIDE AND POLYURETHANE FIBERS, ESPECIALLY WOOL, PREFERABLY UTILIZED ACCORDING TO THE TECHNICALLY USUAL DYEING AND PRINTING PROCESSES FOR REACTIVE DYESTUFFS. They posses an excellent affinity towards wool fibers and they are dyed from an acid, weakly acid or neutral dyeing bath at 70*C to 120*C. They are distinguished by a very good color build-up, a good levelness of the dyeings, very good fastnesses to processing and very good fastnesses to use, also on chlorinated wool. A particular characteristic of these dyestuffs is the very good suitability for the preparation of combination dyeings in mixtures with other dyestuffs on account of the fact that the rate of absorption from the dyeing bath on the wool fiber can be controlled by the pH value of the dyebath.
