The present invention dyes polyester fibers into a vivid navy blue color with excellent color fastness such as light fastness, sublimation fastness, and water fastness. This invention relates to blended dyes for textiles. The blended dye for polyester fibers of the present invention has the following general formula [] [In the formula, X represents a hydrogen atom, a chlorine atom, a nitro group, or a trifluoromethyl group, Y represents a cyano group, a lower alkoxycarbonyl group, or a carbamoyl group, and Z represents a hydrogen atom, a methyl group, a formylamino group, or a lower represents an alkylcarbonylamino group, and R 1 and R 2 are a lower alkyl group, a lower alkyl group substituted with a lower alkoxy group, a lower alkylcarbonyloxy group, a lower alkoxycarbonyl group, or a lower allyloxy group (provided that X is a nitro group). , Y is a cyano group, Z
represents a hydrogen atom, one of R 1 and R 2 may be a cyanoethyl group). ] Disazo dye shown by and (In the formula, X 1 represents a chlorine atom or a bromine atom,
Y 1 represents a hydrogen atom, a methoxy group, an ethoxy group, or a methoxyethoxy group, R 5 represents a methyl group, R 3 and R 4 represent a hydrogen atom, an allyl group, a lower alkyl group, a lower alkoxy group, a lower alkylcarbonyloxy group , represents a lower alkoxycarbonyl group, a lower alkoxy lower alkoxycarbonyl group, or a lower alkyl group substituted with a lower alkoxycarbonyloxy group. ) This is a blended dye for polyester fibers, which is blended with at least one selected from the monoazo dyes shown in the following. To explain the present invention in detail, some of the disazo dyes represented by the general formula [] are new compounds,
Examples of the lower alkylcarbonylamino group represented by Z in the general formula [] include an acetylamino group and a propionylamino group. In addition, the lower alkyl groups represented by R 1 , R 2 , R 3 and R 4 in general formula [] and general formula [] include methyl group, ethyl group, linear or branched propyl group, butyl group, group, pentyl group, hexyl group, heptyl group, octyl group, etc. The substituted lower alkyl groups represented by R 1 , R 2 , R 3 and R 4 include lower alkoxy groups such as methoxy, ethoxy and butoxy groups; lower alkylcarbonyloxy groups such as acetyloxy and propionyloxy groups; or a lower alkyl group substituted with a lower alkoxycarbonyl group such as a methoxycarbonyl group or an ethoxycarbonyl group, and furthermore, as R 1 and R 2 , a lower alkyl group substituted with an allyloxy group,
Furthermore, R 3 and R 4 are lower alkoxy lower alkoxycarbonyl groups such as methoxyethoxycarbonyl group and ethoxyethoxycarbonyl group; or lower alkyl substituted with lower alkoxycarbonyloxy groups such as methoxycarbonyloxy group and ethoxycarbonyloxy group; Examples include groups. The disazo dye represented by the general formula [] (hereinafter referred to as disazo dye []) is, for example, represented by the following formula [] (In the formula, X is the same as the above definition.) Diazotize the aniline represented by the following formula [] (In the formula, Y is the same as defined above.)

34516, Japanese Patent Publication No. 48-6663, Japanese Patent Application Publication No. 55-23190, Japanese Patent Application Publication No. 55-57076, etc. The disazo dye [ ] and the monoazo dye [ ] used as compounding components of the compounded dye of the present invention are each high-performance dyes that can dye polyester fibers in navy color with good fastness. By dyeing polyester fibers by blending and using at least one of each of the monoazo dyes [ ], the dye bath exhaustion rate is dramatically improved compared to when each component dye is used individually. The build-up property is also very good, and highly concentrated dyed products can be easily obtained, and unnecessary loss of dye is also reduced, which is industrially advantageous. The number of component dyes in the blend is preferably 2 to 5, and the blend ratio is preferably about the same amount of each component, but these are not limited depending on the purpose. The blended dye of the present invention can also be obtained by blending the respective intermediates during production (diazotization, coupling). Fibers that can be dyed with the blended dye of the present invention include polyester fibers made of polyethylene terephthalate, polycondensates of terephthalic acid and 1,4-bis-(hydroxymethyl)cyclohexane, and natural fibers such as cotton, silk, and wool. Examples include blended products and blended products of fibers and the above-mentioned polyester fibers. In order to dye polyester fibers using the blended dye of the present invention, since disazo dyes [ ] and monoazo dyes [ ] are insoluble or sparingly soluble in water,
A dyeing bath or printing paste is prepared by dispersing in an aqueous medium using a condensate of naphthalene sulfonic acid and formaldehyde, a higher alcohol sulfate, a higher alkylbenzene sulfonate, etc. as a dispersant by a conventional method. All you have to do is print. For example, in the case of dip dyeing, polyester fibers or their blends can be dyed with excellent fastness by applying ordinary dyeing methods such as high temperature dyeing, carrier dyeing, and thermosol dyeing. In this case, even better results can be obtained if an acidic substance such as formic acid, acetic acid, phosphoric acid or ammonium sulfate is added to the dyeing bath. Next, the present invention will be explained in more detail with reference to examples, but the present invention is not limited to the following examples unless it exceeds the gist thereof. Examples 1 to 13 Disazo dyes [-1] listed in Table-1
[-17] and the monoazo dyes [-1] to [-11] listed in Table 2, either alone or in combination as listed in Table 3, were added in total to 1 g, and 1 g of naphthalene sulfonic acid-formaldehyde condensate and higher alcohol. 100 g of polyester fiber was immersed in a dye bath containing 2 g of sulfate ester dispersed in 3 parts of water and dyed at 130°C for 60 minutes, followed by soaping, washing and drying, resulting in a navy blue dyed fabric. Ta. The light fastness, sublimation fastness and water fastness of the obtained dyed fabric, as well as the temperature stability and PH stability during dyeing of the above dye, were good. In addition, the dye dyed on the dyed fabric was dissolved and extracted using a dimethylformamide solution containing 0.1% phosphoric acid, and the dye was determined colorimetrically.
The dye concentration of each dyed fabric in the example was calculated and shown in Table 3.

It is clear that the dye concentration is significantly improved compared to when each dye is used alone. Therefore, the blended dye of the present invention can be used in a conventional manner as a navy blue series, or it can be used as a black series with extremely high density dyeing. In addition, these dyed products have good color fastness as well as low color rendering properties.
