適当である、という問題点があった。(Problems to be Solved by the Invention) However, the conventional compound represented by the above structural formula Ca) has a group that becomes a reactive group in the molecule. Although advantageous, e.g. P/C
In high-temperature dyeing such as the one-bath one-stage dyeing method of fibers at 130° C., there is a problem in that the affinity for cellulose, which is a matrix structure, is low and the dyeability and build-up properties are poor. In addition, the conventional compound represented by the above structural formula Cb) has a reactive group in the molecule: OOH property, but while it has relatively good property, it has the problem that it is extremely uneconomical due to the reactive group in the molecule. Ta. Furthermore, the conventional compound represented by the above structural formula [C] is a preferable compound that exhibits a high reaction rate with cellulose at a pH of 7 or higher during dyeing, even if only one reactive group is present in the molecule. However, if the pH is weakly acidic, such as 6.5, which is lower than 7, the reaction rate decreases and becomes undesirable. Considering that the pH at the time of dyeing is particularly preferably in the weakly acidic range of 6 or 5 to prevent the decomposition of the disperse dye for polyester used in combination with P/C fibers, the conventional compound is suitable for use with such P/C fibers. There was a problem in that it was clearly unsuitable for one-step bath dyeing.

It exhibits a high dyeing rate against cellulose in ordinary dyeing methods at pH 7 or above, and can yield orange to scarlet dyed products that are thick and have good chlorine fastness and sweat-sunlight fastness. In addition, even in high-temperature dyeing methods of 130°C or higher per step in a weakly acidic dyeing bath for P/C fibers, by using the disazo compound in combination with a disperse dye for polyester, it can be dyed with good color consistency, richness, and chlorine resistance. This has a remarkable effect of industrial value in that an orange to scarlet colored dyed product with good heat resistance and sweat resistance and sunlight fastness can be obtained.
