The aliphatic compound of formula (1) is expressed by the formula (#: written in the form of ``ifd'') C-080,H.Furthermore, the non-conformity is related to the method for producing the disazo compound above the general formula (1). This is achieved by first diazotizing the aromatic amine of the general formula (2) (wherein X has the above meaning), and then converting it into the chemical name of the general formula (3) (wherein M is the above M, representing the taste).゛The body VcO to 2.5 p in a weakly acidic medium, preferably water.
This monoazotization of the general formula (4) (in which M and
The diazotization of the general formula (5) (wherein R and It is characterized by coupling with aromatic amines.

The diazotization of the Hoshichichi amines (2) and (5) is carried out in a locally known method using bile aqueous sodium at temperatures of -50 to +19 C in a turquoise body. Similarly, the V-circular coupling, 1-circular coupling, and the 6-circular coupling are carried out in a manner known per se. The one-step coupling reaction is carried out in a strongly acidic range, especially at a temperature of 5 to 5 UC. The coupling reaction at the crab stage is particularly carried out in the low to medium range and at a temperature of 5 to 30C.

As a compensating agent for the adjustment of the pH range during the reaction of onicablink, preferably a weak inorganic or Morganic acid, an alkali or alkaline earth metal salt of oxalic acid. Alternatively, Rin Kai's hostile salt is used. In addition, sodium carbonate and potassium carbonate, sodium acetate, sodium borohydride, and especially sodium hydroxide are passed through this column.

Compounds according to the invention of the general formula (1) in which X represents a β-sulfatoethyl group can also be prepared according to the invention by the method described above, in which one or both of the residues X of the general formula (2) One or both of the aromatic amines of the formula - in which both residues X represent a β-hydroxyethyl group are coupled with the 1-7 < no 8-naphthol-6,6-disulfone branch of the formula (3J) and thus 7 and general formula (1), provided that 1-AX
One or both of the β-hydroxyethyl groups? A disazo compound having the structure shown in the formula (1) can be converted to 0 using a deoxidizing agent such as Iso-enba or chlorosulfonic acid by a method known per se.
The VC equivalent sulfate compound according to the invention can be prepared by frequently changing rest periods.

Compound-1 by unexploded r-A Of course, from its synthetic mixture, after its preparation, by a generally known method,
For example, sodium chloride or noa chloride.
It can be isolated by precipitation of the glandular bodies with Jum, followed by filtration, or by evaporation of the phlegm itself, for example, by evaporation of the phlegm itself. If the non-inventive method of isolation of the compound is selected, the reaction bath liquid may contain a large amount of carcass salts, and the sulfuric acid present in the light SIJ bath liquid may be precipitated. Therefore, it is rejected as Icgi calcium and removed by separation by filtration. Numerous gift ceremonies (1,
It is desirable to supply the reaction bath containing this compound of ) directly as a liquid preparation for skin color use, optionally after addition of a fine and/or mild aphrodisiac.

The novelty of the present invention, 84, is a material layer or leather made of hydroxy- or carbibonamide-based solid fibers, preferably natural or bound cellulose or natural, regenerated or synthetic fibers.
#R navy blue material made of polyamide, lint, hemp, jute, viscose, human silk, wool, silk, polyamide-6, polyamide-6,6, polyamide-11 and polyamide-11
4. Suitable for bamboo as a reactive dye for dyeing or printing. In particular, the dyestuff compounds are suitable for dyeing or printing cellulose fiber materials.

The cultivated proboscis has water bathability, especially fiber length 1, on the above-mentioned substrate.
It is applied and followed analogously to the known and current dyeing and printing methods for color dyeing. This gives a commercially available imperial black dyeing and printing of color strength, levelness and very good fastness. Of the fastness, Nikko Kengyu is strong, strong against alkaline and poe soup, ironing is -,
Folding and blanching fastness, bath agent and dry cleaning fastness, water and seawater fastness, salt bath water fastness and oxidation, and alkali fastness are emphasized in the poem.

The revised section L3F3 further describes the use of the above-mentioned fibrous oblique text 1- for dyeing or decontamination of leather, or the use of the above-mentioned textile material diagonal text 1- for the dyeing or decontamination of leather, or the conversion according to the present invention - 8' of the invention, which is known in the art. and a process for dyeing or printing fibrous materials or leather, which is applied to the fibrous material and rolled for 7M analogous to conventional methods.

For example, this 'fh' is a cellulose ultrafine material and sometimes a normal dyeing aid? Using the alkaline action 1 crude agent from a long bath by exhaustion method in an aqueous bath containing 60 to 1 ub
The process is carried out at a temperature of C, the fiber material being dyed onto the valve sleeve with a good dyeing yield.

■Shiba's V'C staining was obtained on cellulose and visceral fiber materials by the known and commonly used bagging method, with a dyeing yield similar to that of colleagues; +ij+Jzs = 7/reactive agent - which is used on the birch miscellaneous material at the same time as or after the application of the dye. This can be carried out by treatment in an oil bag at room temperature or at temperatures up to 6 UC for a period of 2 to 2 hours, or by steaming or by dry heat. Unsolidified dyes are easily washed out.

It is known and common decontamination and +i! that the compound cut printing method according to the present invention can be carried out in Europe! It is carried out similarly to the shield method (for cellulose fiber #: for total dyeing).

In this case, the one-phase method is more important) IJum or other acid binder? If the blood returns to potassium, charcoal, IJum or potassium, caustic sorter solution, potash solution or trichlor vinegar) in the printing paste in the presence of IJum and subsequently at 101 to 103C. Decontamination by steaming or two-phase process with neutral or mild mineral paste and subsequent decontamination with hot electrolyte and alkaline coating or over-contamination with alkaline and alkaline treatment. Pazinking and pulling iθ1 by heavy duty, steam or dry heat to achieve an excellent level of 11-ring coloring and a 1M color strength to create a white base. Good printing (4I and 7'L).

Dyeing of polyurethane fibers or polyurethane fibers is usually carried out from the septic stage. In order to maintain the pH value of 7-IT, the liquid can be cooled with a chemical agent such as chlorine or chlorine and ammonium. 1st history of dyeing E
I don't recommend removing the uniformly dyed cow in the "J 1". It can also be carried out even if it is dyed completely.
