【発明の詳細な説明】 〔産業上の利用分野〕 本発明は黒色用反応染料混合物に関するものであり、
詳しくは、各種光源下において変色のない黒色染色物を
得るための反応染料混合物に関するものである。The present invention relates to a black reactive dye mixture,
More specifically, the present invention relates to a reactive dye mixture for obtaining a black dyed product without discoloration under various light sources.

品イメージを大きく損ねる欠点がある。Reactive dyes are widely used as dyes for dyeing cellulose fibers and nitrogen-containing fibers, and many of these dyed materials change their hue under various light sources. That is,
Compared to the standard hue when the dyed material is viewed with clear northern window light,
When viewed under the sunrise or sunset, the hue when viewed under a photographing spotlight and various illumination light sources is often different. Such a dyed product having a large hue difference causes a reduction in commercial value. In particular, in the case of a black dyed product used for high-end clothing, many of the dyed products have a reddish hue under irradiation of a photographing spotlight, and have a disadvantage that a product image is greatly impaired.
このような傾向は分散染料を用いて染色されたポリエ

I have. However, in the case of dyeing using a reactive dye, almost no studies have been made to improve the hue difference under various light sources.

色用反応染料混合物に存する。The present inventors have studied a method of dyeing a cellulose fiber or a nitrogen-containing fiber into a black color using a mixture of a navy blue and an orange reactive dye. It was found that the difference in hue caused by the light source difference could be suppressed. That is, the present invention relates to a black reactive dye mixture comprising at least a navy blue reactive dye and an orange reactive dye, and as a navy blue component, in the form of a free acid, (Wherein, X represents a —CH ＝ CH 2 group or a —C 2 H 4 OSO 3 H group)
And using, as an orange component, 0.1 to 4 times by weight of a free acid in the form of a free acid with respect to the navy blue component. [Where D is Wherein Z is an —OH group, —CHCHCH 2 group or —C 2 H
4 OSO 3 H group), R represents a hydrogen atom or a methyl group, and Y represents Represents a group. However, when Z is -OH group, Y is It is. And a reactive dye mixture for black.
以下、本発明の詳細に説明する。 Hereinafter, the present invention will be described in detail.

る。In the present invention, a water-soluble reactive dye represented by the general formula [A] is selected as the navy blue component, while a water-soluble reactive dye represented by the general formula [B] is selected as the orange component. The combination is characterized in that the orange component is 0.1 to 4 times by weight, preferably 0.2 to 3 times by weight of the navy blue component.
In the present invention, by dyeing a cellulose fiber or a nitrogen-containing fiber black using a mixture in which these two components are blended, it is possible to obtain a dyed material having no hue difference even under various light sources.
前示一般式〔Ａ〕及び〔Ｂ〕の反応染料は公知のもの
であり、各々、公知法に従って製造することができる。
また、本発明に係る反応染料は遊離酸又はその塩の形で

はない。In the present invention, a black dye is obtained by mixing the above two components of the navy blue component and the orange component. However, if necessary, a red component, a yellow component and / or a blue component may be mixed. That is, the effect of suppressing hue difference under various light sources of the present invention is achieved by the combination of the general formulas [A] and [B] shown above. The effect is basically the same.

のが良い。Therefore, in some cases, a third component other than the above-mentioned general formulas [A] and [B] may be added to the navy blue component or the orange component. If the amount of the third component is extremely large, the effect of the present invention is diminished. Therefore, the amount of the third component is usually 4 times by weight, preferably 3 times by weight or less based on the navy blue component and the orange component specified in the present invention. Is good.
