    摘要： The present invention relates to a novel blue dye compound represented by Formula (1) as shown below, which can be synthesized without a dianisidine compound used for a raw material and can dye a cellulosic high molecular material to provide the blue dyed product that has a high color value, a good build-up and various kinds of good fastness; a method for dyeing a cellulosic high molecular material by using the same; and a cellulosic high molecular material dyed with the same. A formazan compound represented by (In Formula (1), R1 is hydrogen, sulfo, hydroxy, chloro, methoxy, carboxyl or alkyl; either of R2 and R3 is hydrogen and the other is sulfo; X is morpholino, 2-hydroxyethylamino or bis(2-hydroxyethyl)amino; and Y is a phenylene diimino represented by Formula (2) as shown below (In Formula (2), R4 is sulfo or carboxyl)) or the salt thereof.

    摘要： Heavy-metal-containing bisformazan dyestuffs of the formula ##STR1## WHEREIN A.sub.1, A.sub.2, B.sub.1 and B.sub.2 are the same or different and each represents an unsubstituted or substituted o-phenylene radical or an o-naphthylene radical,R.sub.1 and R.sub.2 are the same or different and each represent a monovalent organic radical,Me.sub.1 and Me.sub.2 each represent nickel or copper,X.sub.1 and X.sub.2 are the same or different and each represents a metal-binding substituent connected to A.sub.1, B.sub.1, A.sub.2 or B.sub.2 in a position ortho to that to which the nitrogen is linked,Y represents the radical of a dibasic carboxylic acid or a radical which is derived from an, at least, bifunctional heterocyclic compound,Z represents a salt-forming water-solubilizing group, dissociating acid in water, selected from --SO.sub.3.sup..crclbar. M.sym. and --COO.sup..crclbar. M.sup..sym.wherein M.sup..sym. represents a cation,N represents a number from 2 to 6, andWherein aromatic radicals present may contain further substituents known per se for use in azo dyestuffs, and wherein the grouping --NH--Y--HN-- is bound directly or via a bridging member to a ring carbon atom of A.sub.1, A.sub.2, B.sub.1, B.sub.2, R.sub.1 or R.sub.2 ,which bis-formazans are substantive dyestuffs suitable for the dyeing or printing of textile material made from natural or regenerated cellulose. The aforesaid bis-formazan dyestuffs are distinguished by high coloring strength and substantivity to cellulose textile material. The dyeings obtained therewith are of a pure shade of color and have good fastness properties, especially to light and wet.
