A fiber reactive dye having the formula <IMAGE> wherein R1 and R3 are independently selected from the group consisting of; hydrogen; an alkyl group having from one to four carbon atoms; the foregoing alkyl group further substituted with one or more groups selected from hydroxy; amino; sulfo; halogen; an aryl radical; a heterocyclic radical or combination thereof; where for R3 said amino group maybe further substituted by a nitrogen heterocyclic fiber reactive group of the series: 1, 3, 5 mono or dichloro triazinyl; 1, 3, 5 mono or difluoro triazinyl; trichloropyrimidinyl; difluoropyrimidinyl; or monochlorodifluoro pyrimidinyl; where the nitrogen heterocycle may be further substituted by an: alkyl; or aryl amino group; wherein B is selected from the group consisting of a C2 to C4 alkyl chain; a substituted aryl or a heterocyclic radical; wherein X is selected from the group consisting of SO3H; SO3Na or a hydroxy group; and wherein Q1 and Q2 are independently selected from diazo components.
