Abstract

NEW MATERIAL:An azo compd. of formulaI(where R' is a 5-8C alkyl group or a 5-8C alkoxyethyl group; R<2> is a cyanoalkyl (1-3C) group, a 1-4C alkoxycarbonylmethyl group or a 1-4C alkoxyethoxycarbonylmethyl group; X is H, methyl group, acetylamino group or Cl). USE:The monoazo dye is used for dip dyeing and printing of polyester fiber, etc. in bright blue to green colors.

Description

[Detailed Description of the Invention] The present invention relates to a monoazo dye for synthetic fibers*
Specifically, the present invention relates to an azo dye that dyes synthetic fibers with a vivid blue to green color.The present invention will be described in detail below.

The dye related to the present invention has the following general formula (13 (wherein I is 0
．． , , alkyl group or 0. , , represents an alkoxy ether group, I represents a cyano O3-1 a, 'J-4 flukoxycarbonylmethyl group, and an alkoxyethoxycarbonylmethyl group, I represents a hydrogen atom,
A dye represented by a methyl group, an acetyl group, or a chlorine atom) and represented by the general formula [1] shown above is a dye represented by the above general formula [1].
! - *S+ is produced by coupling a diazonium salt of thiophene with an aniline represented by the following general formula (13 Specific examples of the anilines represented by the formula (1) include iris-hexyl-1-(l-cyanoethyl)-4-)luidine, iris-henakasilu-(r-cyanoethyl)aniline, and J'' 741 ?Ruamino-Natsu-Heme Sil-1-Cyanomethyl 7 items Phosphorus, Natsu-(/-hexyloxyethyl)-(l-cyanoethyl)-US-) Luidine, Sho-octyl-■-(metho-octyl-) carbonyl/?ru)

Polyethylene terephthalate, terephthalic acid and 1.
It is preferable to use a polyester fiber made of a polycondensate with bis-bis-(human tetraoxymethyl) Schiffer.
The dye represented by the general formula [1] shown above is used in a conventional manner7.
Using a dispersant such as talenesulfonic acid, formaldehyde and O condensate, higher alcohol kll@ester, higher alkylbenzene sulfonate, etc., it is dispersed in an aqueous medium to prepare a printing lake before dyeing. (For example, for pigeon houses that are dyed by dip dyeing, ordinary dyeing methods such as high-temperature dyeing, carrier dyeing, and nanosol dyeing can be applied.) K
Dyeing with excellent li ratio can be applied. For even better results, add an acidic substance such as formic acid, acetic acid, phosphoric acid or sulfuric acid to the dyeing bath in the pigeon coop. The invention will be explained more specifically with reference to examples. Example I A noazo dye represented by the following structural formula, 0.1 j, 7-talenesulfone-formaldehyde condensate/l, and a higher allyl. A dyeing bath was prepared by dispersing water JtK containing sulfuric acid ester KJll, and polyester fiber 1009 was immersed in this dyeing bath, /J
After dyeing at 0.degree. C. for 60 minutes, soaping, rinsing and drying the fabric, the polyester fabric was dyed in a bright true color with good light resistance and sublimation resistance.

The dyes used in this example were 1-a-denoJ, j-m-

Turtle X (acetone) is 43 Tei n Otori and there are 6 of them.

Example - Mono-7 dye represented by the following structural formula 0.1j was dispersed in water containing 7talenesulfone-formaldehyde condensate/, zl and higher alcohol am ester/It, and dissolved in methylnaphthalene system. Prepare a dyeing bath by adding Yariky 1177 and add polyester fiber 1114 to this dyeing bath.
After immersing 100 g of the fabric and dyeing it at 100° C. for up to minutes, washing it with water and drying it, a polyester cloth dyed in vivid blue with good color resistance, light resistance, and sublimation stiffness was obtained.

The polyester used in this Example F1 was produced by coupling it with Co-A-N-ethoxycarbonylmethylaniline. The λwax (acetone) of this product is A J J

Example J Monoazo dye represented by the following structural formula 0. Polyester fibers were dyed using JJL in the same manner as in Example 1, and a polyester cloth having good firmness and being dyed in a clear blue color was obtained.

The dye used in this example was diazotized t,, m-(
/-hebutyloxyethyl)-Natsuichi methoxycarbonylmethyl-m-toluidine was produced by coupling with m-toluidine, and the λwax (acetone) of the 90 products was baonn.Example D~/1 Table 7 below Polyester fibers were dyed according to the method of Example I using the monoazo dye shown in Table 1, and a dyed fabric with the color tone Ω shown in the table was obtained.
