[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a purple reactive dye composition comprising a red reactive dye and a blue reactive dye, and a brown reactive dye composition obtained by further adding a yellow reactive dye thereto. Further, the present invention relates to a reactive dye composition having a uniform dyeing speed for each of red, blue and yellow components and a dyeing method using the same.

[0002]

2. Description of the Related Art Reactive dyes have a clear hue and are abundant.
Moreover, it is widely used because of its excellent robustness. However, reactive dyes have different dyeing rates depending on the types of reactive groups. Further, the dyeing speed also differs depending on the structure. For example, the following general formula [I-

Has a meaning)), and m represents 0 or 1. ] The vinyl sulfone red reactive dye represented by the formula [3] also has a small dependency on the inorganic salt in the exhaust dyeing method, and is excellent in chlorine fastness and build-up property. Therefore, there are many demands for utilizing this excellent property as a red primary color for dyeing a wide range of hues.

[0009]

However, when this red dye is mixed with a blue dye so as to obtain a purple hue and dyed, the hue changes as the dyeing time elapses due to the difference in dyeing speed. Changes, and it is difficult to obtain color reproducibility. Specifically, for example, in the form of free acid, the following general formula [II]

When dyeing is carried out using the purple reactive dye composition obtained by blending with the blue reactive dye represented by [III], [IV] and [V], the dyed cloth becomes blue as the dyeing time elapses. The taste changes from red to red. This is a disadvantage in obtaining the reproducibility of staining.

Therefore, it is desired to develop a blue reactive dye having a uniform dyeing speed with the red reactive dye represented by the above general formulas [IA] and / or [IB]. This is not limited to purple dyeing, and in brown dyeing as well, it is required to select and develop a blue reactive dye as well as a yellow reactive dye having a uniform dyeing speed.
