が望ましい。2. Description of the Related Art As a material for an automobile seat, a cloth made of polyester fiber is widely used. In recent years, as the interior of automobiles has become fashionable, a colorful seat color has been required. However, in the case of an automotive seat, the seat is often exposed to sunlight under high temperature in a closed room, so that the seat tends to fade, and it is difficult to maintain a beautiful color for a long time. Accordingly, it is desirable to use a dye excellent in light fastness, sublimation fastness and temperature dependency as a dye for dyeing polyester fibers for automobile sheets.

度依存性が不充分である。However, conventionally, there are few dyes excellent in all of light fastness, sublimation fastness and temperature dependency, and no satisfactory dyes have been found as yellow disperse dyes for automobile sheets. For example, a dye represented by the following structural formula [A] is known from British Patent No. 1105568, but this dye is excellent in light fastness and can be applied to dyeing polyester fibers for automobile sheets. However, the temperature dependency is insufficient.

本発明を完成した。SUMMARY OF THE INVENTION In view of the above circumstances, the present inventors have determined that the yellow disperse dye represented by the formula (A) has excellent temperature fastness and good dye fastness while maintaining excellent light fastness. As a result of various investigations on the method of improving, it was found that when the dye of the formula (A) and the yellow dye of the formula (B) are mixed and used, the sublimation fastness is better as compared with the case where the dye is used alone. The inventors have found that the temperature dependency is improved while maintaining the temperature in a proper state, and completed the present invention.

ある。That is, the gist of the present invention is to provide 85 to 50% by weight.
The disperse dye mixture comprises 15 to 50% by weight of the naphthalene dye represented by the formula [B] with respect to the anthraquinone dye represented by the formula [A]. Hereinafter, the present invention will be described in detail. In the present invention, the yellow disperse dyes represented by the formulas (A) and (B) are mixed and used, and the mixing ratio is the dye of the structural formula (A) to the dye of the structural formula (B). 85 to 50% by weight: 15 to 50% by weight, preferably 80 to 60% by weight: 20 to 40% by weight.

も可能である。When the amount of the dye of the formula [B] is too small, the effect of improving the amount of dyeing and the temperature dependency is small. Conversely, if the amount of the dye of the formula [B] is too large, the effect of improving the fastness to sublimation is small. In the present invention, two kinds of disperse dyes represented by the formulas (A) and (B) are used in combination as a yellow component. However, in order to dye to a desired color tone, it is blended with a blue component and a red component. It is also possible to use.
