The present invention relates to dispersed water-insoluble dye compositions. More specifically, the present invention relates to a dispersed water-insoluble dye composition having excellent dyeing properties, particularly dispersion stability. The dye of formula () is already known and is one of the typical bright blue dyes used for dyeing hydrophobic synthetic fibers. However, although the dye of formula () has a clear blue color and is widely used due to its excellent fastness, it has poor dispersion stability in high-temperature water (hereinafter simply referred to as dispersion stability). It had the disadvantage of being inferior. For this reason, in dyeing factories, large amounts of dispersion aids are added in combination to prevent the formation of aggregates, although this is disadvantageous in terms of cost. However, this is still insufficient, especially in recent years, In the rapid dyeing method that is becoming popular, there is a strong desire for improvement because aggregates are often generated during dyeing and the commercial value of the dyed product is lost. The present inventors have made extensive studies to solve the above problem, and have found that the problem can be solved by blending the dye of formula () with an anthraquinone dye similar to this. That is, the present invention is based on the formula () 90-10% by weight of the dye represented by the formula (), ()
or() One or more types of dyes shown in 10~
90% by weight of the dispersed water-insoluble dye composition. In the dye composition of the present invention, one or more of the dyes represented by (), (), or () are added to the dye of formula () from the synthesis of the dye of formula () to the completion of commercialization. It can be manufactured by mixing or blending during the process. The proportions of the composition of the present invention are 90 to 10% by weight of the dye of the formula () and the dye of the formula (), (), () as the pure dye content.
10-90% by weight of dye, preferably dye of formula ()
85-15% by weight, and 15-85% by weight of dyes of formulas (), (). When the amount of dyes represented by formulas (), (), and () is less than 10% by weight or more than 90% by weight, the effect of improving dispersion stability tends to gradually decrease. In the present invention, the most preferred combination is formula () and formula () or formula (). The dye composition of the present invention may be in the form of a dispersion, usually called a paste or liquid, or a powder obtained by drying. Further, the dye is pulverized by a conventional method using a dispersant. The dye composition of the present invention may optionally contain other toning dyes, a drying inhibitor or preservative for liquid products, or a dust-scattering preventive agent for powder products. The dyes of formulas (), (), and () have similar hues to the dyes of formula () on hydrophobic synthetic fibers, especially polyester fibers, so even if they are mixed in any ratio, there will be only a slight change in color tone. Therefore, there is no need to adjust the color using dyes of other colors, or even if the color is adjusted, only a small amount of the dye for color adjustment is used. Therefore, the dye composition of the present invention can be replaced with another product without changing the dye of formula () and the dye formulation, and has excellent dispersion stability, which eliminates the risk of dyeing spots caused by aggregate formation. can be avoided. In the present invention, although the dyes of formula () and formula (), (), or () have extremely poor dispersion stability when used alone, by mixing them, the dyes are dramatically and synergistically dispersed. The improvement in stability was completely unexpected. Due to its improved dispersion stability, the dye composition of the present invention produced in this manner can be used for hydrophobic fibers,
In particular, the benefits obtained are greatest in dyeing polyester fibers, but it can be suitably used in both printing and continuous dyeing. Furthermore, since a large amount of dispersing aid is not required, the dye purity of the product is not reduced, and it also has advantages in terms of cost. The present invention will be specifically explained below using Examples. In the text, parts and % represent parts by weight and % by weight. In addition, the high temperature water dispersion stability dyeing test (hereinafter simply referred to as dyeing test) in the Examples was conducted in the following manner. [Dyeing test method] Test dyeing device Colorpet (Nippon Senzo Kikai Co., Ltd.)
Wrap a polyester jersey cloth tightly around the inner cylinder of a fabric dyeing holder (manufactured by Co., Ltd.) so that there are no gaps, and secure the top and bottom ends of the holder with rubber bands so that they do not come loose. After setting the outer cylinder thereon, it is placed in a dyeing pot in which a dye bath has been prepared separately, and the temperature is rapidly raised from 90°C to 115°C, and then held at 115-116°C for 20 minutes. The total amount of the dye bath is 30 times the weight of the fiber, and the pH of the dye bath is adjusted to about 5 using a predetermined amount of dye and acetic acid and sodium acetate as pH regulators. in this case,
No auxiliaries are added. After that, it is rapidly cooled to 90℃, the dyed material is immediately taken out, washed lightly with water, and then spread out and air-dried. After air-drying, visually determine the amount of dye aggregates adhering to the fibers in contact with the liquid flow opening of the dyeing holder inner cylinder. When the judgment was a symbol, the following criteria were used. ◎: Adhesion of aggregates is not observed. ○: Only slight adhesion of aggregates is observed. Δ: Slightly more adhesion of aggregates was observed. ×: Adhesion of aggregates is observed in large amounts. XX: Significant adhesion of aggregates is observed. According to this staining test, for practical purposes, it is necessary that there is only a slight amount of adhesion of aggregates (○ mark) or more. Example 1 30 parts of the dye of formula () was charged into 200 parts of water together with 40 parts of a formalin condensate of naphthalene sulfonic acid and 30 parts of a ligninsulfonic acid dispersant, and the mixture was atomized to obtain a dispersion (1). 30 parts of dye (), 40 parts of formalin condensate of naphthalene sulfonic acid, lignin sulfonic acid dispersant
It was added to 200 parts of water together with 40 parts and atomized to obtain a dispersion (2). . The thus obtained dispersions (1) and (2) were each spray-dried to obtain a dispersible powder dye composition. The obtained powder dye compositions were mixed at the blending ratio shown in Table 1, and a dyeing test was conducted to obtain the results shown in the right column. The amount of the dye composition used was 8.0% based on the weight of the object to be dyed (polyester jersey). From Table 1, it can be seen that the dispersion stability of the dye of formula () is extremely poor, but the dispersion stability is significantly improved by mixing the dye of formula ().

A staining test was carried out using the amount of %. In addition, a staining test was also conducted using the dispersion liquid (1) alone. As a result, when dispersion (1) was used alone, an extremely large amount of dye aggregates was observed to adhere, whereas dispersion
In the case of the present invention, in which (1) and (3) were mixed in a 1:1 ratio, almost no dye aggregates were observed, and extremely excellent dispersion stability was exhibited. Example 3 Dispersion (4) was prepared in the same manner as in Example 1 except that dye () was used instead of dye ().
