To obtain the subject dye composed of a compound having a specific structure, exhibiting high fixing yield and bonding stability to a fiber, a enabling easy washing of non-fixed part and suitable for the dip dyeing or printing of textile material.

The objective dye is a compound expressed by formula I [B is a cross-linking member of the formula NR2(alk)-NR3 (R2 groups are each independently H or a 1-4C alkyl; R3 is a hydroxy-substituted 1-6C alkyl; alk is a straight or branched-chain 2-12C alkylene), etc.; (R)n is n-groups such as a 1-4C alkyl, a halogen or sulfo; (R')m are m-groups such as a 1-4C alkyl, a halogen or sulfo; R1 and R'1 are each independently H or a 1-4C alkyl; X1 and X2 are each independently a halogen, 3-carboxypyridin-1-yl, etc.; Y and Y' are each independently vinyl, etc.; (p) and (q) are each independently 0 or 1; (n) and (m) are each independently 0, 1 or 2]. The compound of formula I can be produced e.g. by reacting the compounds of formula II, formula III, etc., with each other.
