The present invention relates to monoazo dyes for polyester fibers. Specifically, the present invention relates to a monoazo dye that dyes polyester fibers, particularly in a bright blue color with excellent water fastness after resin processing, PH stability during dyeing, and light fastness. Structural formula below The dye represented by is described in British Patent No. 774611 and is also known to dye polyester fibers blue. The present inventors have conducted intensive studies to improve the properties of dyes having the above-mentioned basic skeleton. As a result, the following general formula [] (In the formula, R 1 represents a lower alkyl group, a lower alkoxyethyl group, or a lower alkoxyethoxyethyl group, and R 2 represents a methyl group or an ethyl group.) When dyeing fibers, compared to using the above-mentioned known dyes,
The present invention was achieved by discovering that it has excellent light fastness, water fastness after resin processing, and PH stability during dyeing. The dye represented by the general formula [] shown above is, for example, the dye represented by the following structural formula [] The diazonium salt of 2-amino-3-nitro-5-acetylthiophene represented by the following general formula [] It can be produced by coupling with an aniline represented by the formula (wherein R 1 and R 2 are the same as defined above). R 1 in the above general formulas [] and [] is a lower alkyl group such as a methyl group, an ethyl group, a linear or branched propyl group, a butyl group; a methoxyethyl group, an ethoxyethyl group, an n-
Examples include lower alkoxyethyl groups such as propoxyethyl group and n-butoxyethyl group; lower alkoxyethoxyethyl groups such as methoxyethoxyethyl group, ethoxyethoxyethyl group, n-propoxyethoxyethyl group, and n-butoxyethoxyethyl group. Fibers that can be dyed with the monoazo dye of the present invention include polyester fibers made of polyethylene terephthalate, polycondensates of terephthalic acid and 1,4-bis-(hydroxymethyl)cyclohexane, or fibers such as cotton, silk, and wool. Examples include blended products and blended products of natural fibers and the above-mentioned polyester fibers. In order to dye polyester fibers using the dye of the present invention, a resolving agent such as a condensate of naphthalene sulfonic acid and formaldehyde, a higher alcohol sulfate ester, or a higher alkylbenzene sulfonate is used in a conventional manner. Dyeing or printing may be carried out by dispersing the dye represented by the formula [] in an aqueous medium to prepare a dyeing bath or printing paste.
For example, when performing dyeing, high temperature dyeing method,
By applying conventional dyeing methods such as carrier dyeing and thermosol dyeing, it is possible to dye polyester fibers or their blended and woven products with excellent fastness. Further, in some cases, even better results may be obtained by adding an acidic substance such as formic acid, acetic acid, phosphoric acid, or ammonium sulfate 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. Example 1 Structural formula below A dyeing bath was prepared by dispersing 0.5 g of the monoazo dye represented by 3 in water 3 containing 1 g of naphthalene sulfonic acid-formaldehyde condensate and 2 g of higher alcohol sulfate. When 100g of polyester fiber was immersed in this dyeing bath and dyed at 130℃ for 60 minutes, it was soaped, washed with water, and dried, and the light fastness was 5.
A polyester cloth dyed in bright blue with good quality was obtained. In addition, PH stability during staining (PH7/PH
The dyeing rate ratio of No. 5) was as good as 90%, and the water fastness of the obtained dyed fabric after resin processing was also excellent at grade 4-5. The dye used in this example was 2-amino-3-
It was produced by diazotizing nitro-5-acetylthiophene according to a conventional method and coupling it with 3-acetylamino-N.N-di(n-butoxyethyl)aniline. The λmax (acetone) of this product is 616n
It was m. Example 2 Structural formula below 0.5 g of the monoazo dye represented by is dispersed in water 3 containing 1.5 g of naphthalene sulfonic acid-formaldehyde condensate and 1 g of higher alcohol sulfate ester, and a methylnaphthalene carrier 15
A dyeing bath was prepared by adding g. When 100g of polyester fiber was immersed in this dyeing bath and dyed at 100℃ for 90 minutes, it was soaped, washed with water, and dried, and the light fastness was 5.
A polyester cloth dyed in bright blue with good quality was obtained. In addition, PH stability during staining (PH7/PH
The dyeing rate ratio of No. 5) was as good as 85%, and the water fastness of the resulting dyed fabric after resin processing was also excellent at grade 4-5. The dye used in this example was produced by diazotizing 2-amino-3-nitro-5-acetylthiophene in a conventional manner and coupling it with 3-acetylamino-N.N-di(ethoxyethyl)aniline. did. The λmax (acetone) of this product was 612 nm. Example 3 Structural formula below When polyester fibers were dyed using 0.5 g of the monoazo dye represented by the formula according to the method of Example 1, a polyester cloth dyed in vivid blue with good light fastness of grade 5 was obtained. In addition, the PH stability (dying rate ratio of PH7/PH5) during bright colors was as good as 80%, and the water fastness of the resulting dyed fabric after resin processing was also excellent at grade 4. The dye used in this example was obtained by diazotizing 2-amino-3-nitro-5-acetylthiophene in a conventional manner and coupling it with 3-acetylamino-N.N-di(methoxyethoxyethyl)aniline. Manufactured. The λmax (acetone) of this product is
It was 611 nm. Example 4 When polyester fibers were dyed according to the method of Example 1 using the monoazo dyes shown in Table 1 below, a dyed fabric with good light fastness and the color tone shown in the table was obtained. . In addition, the PH stability during dyeing was good, and the water fastness of the resulting coating after resin processing was also excellent.
