| 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 <CHEM> (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 <CHEM> <CHEM> (In Formula (2), R4 is sulfo or carboxyl)) or the salt thereof. |
