    摘要: WHEREIN R1 represents H or an alkyl group and R2 represents an alkyl, aryl or substituted aryl group, or R1 and R2 together form with the N atom a five or six-membered heterocyclic ring, EACH N INDEPENDENTLY REPRESENTS 0 OR 1, EACH Y independently represents H, a methyl group or the two together represent an oxygen atom, X represents SO3 or may be CO2 if Y, Y is -O-, Am is the NH group or an amine or a diamine radical having the SO2 group attached to the nitrogen or one of the two nitrogen atoms, and Z is a cellulose-reactive group attached to a carbon or nitrogen atom in the radical Am. They provide brilliant yellowish-red to bluish-red shades having a surprisingly high lightfastness.

    Reactive dyestuffs of the triphenylmethane or xanthene series having the formula:
