Abstract
Abstract A dye, which is suitable for dyeing cellulosic fiber materials, of the formula, <IMAGE> wherein R and R' are each hydrogen, a C1-C4 alkyl, or C1-C4 hydroxyalkyl, m is an integer of 1 to 6, n and n' are each an integer of 2 to 4, and when m is 2 or more, n may be the same or different integer between 2 and 4, X is hydrogen or a group of the formula <IMAGE> (wherein Q is a dye residue, R1 is hydrogen or a C1-C4 alkyl and R2 is halogen); Y is hydrogen or a group of the formula <IMAGE> (wherein Q' is a dye residue, and when m is 2 or more, Q's may be the same or different, R1' is hydrogen or a C1-C4 alkyl and R2' is halogen); Z is hydrogen or a group of the formula <IMAGE> (wherein Q'' is a dye residue, R1'' is hydrogen or a C1-C4 alkyl and R2'' is halogen, Q, Q' and Q'' may independently be the same or different and X, Y and Z are not hydrogen at the same time).
