<Problems to be Solved by the Invention> Conventionally, this type of reactive dye has been widely used in the fields of dyeing and printing textile materials. However, the current state of the art is not satisfactory for Pe in terms of high requirements regarding suitability for specific dyeing methods and high requirements regarding fastness and dyeability of dyed products.

It is strongly desired that the above-mentioned known reactive dyes be further improved in terms of solubility, stability over time, and fastness (for example, fastness to acid hydrolysis).

The present inventors have completed the present invention as a result of intensive studies aimed at improving the above-mentioned known dyes and finding a new reactive dye that can broadly satisfy the requirements required for dyes.

Means for Solving the Problems> The present invention provides the following general 2(1) in the form of a free acid [wherein Q represents -3O2CH2CH,08O3H]. ]General General II I
) and (IT) are the reactive dyes described in JP-A-50-1
It can be manufactured by the method described in Japanese Patent No. 78.

The dye composition of the present invention has the above-mentioned general two (I) and (II).

It is 25% by weight.

In the present invention, the monoazo reactive dyes shown in general 2 (I) and (■) may be mixed by being synthesized simultaneously in each synthesis, or they may be synthesized separately and then mixed. May be mixed. Furthermore, they may be mixed during dyeing.

The composition of the present invention has fiber reactivity and can be used for dyeing or printing materials containing human-loxy groups or carbonamide groups. Preferably, the material is used in the form of a fibrous material or a blend thereof.

A reactive dye represented by 1 to 50 percent by weight based on the dye
In the free acid form of the following general 2 (II) 110, S [wherein Q'' represents -5O2 white (.CH2, in the following general 2 (1), Q is O- with 7 groups When substituted at Tl'1 or p-position, Q" is o-, m-, respectively
or l)-position. ] The present invention provides a reactive dye composition characterized by containing the reactive dye shown in the following, and a method for dyeing or printing a fiber material characterized by using the same.

The reactive dyes represented by the general formulas (1) and (■) in the composition of the invention are present in the form of free acids or in the form of their salts, especially alkali metal salts and alkaline earth metal salts, especially soda Preferred are salts, potassium salts, and lithium salts.

Human(i) group-containing materials are natural or synthetic human(i) group-containing materials, such as cellulose fiber materials or their regenerated products and polyvinyl alcohol. Cellulose fiber materials include cotton, other vegetable fibers, such as , hemp, jute and ramie fibers are preferred.Regenerated cellulose fibers include, for example, viscose stable and filament bis-1-seed fibers.

Materials containing carbonamide groups are, for example, synthetic and natural polyamides and polyurethanes, especially in the form of fibers, such as wool and other animal hairs, silk, leather, polyamide-6,
6, polyamide-6, polyamide-11 and polyamide-4.

The composition of the present invention can dye or print the above-mentioned materials, especially the above-mentioned fiber materials, by a method depending on their physical and chemical properties.

For example, in the case of exhaust dyeing on cellulose fibers, in the presence of an acid binder such as soda carbonate, sodium phosphate or caustic soda, a neutral salt such as mirabilite or common salt is optionally added, and if desired, a solubilizer is added. , use a penetrant or leveling agent together,
It is carried out at relatively low temperatures. The neutral salts which accelerate the exhaustion of the dyestuff can be added only after the actual dyeing temperature has been reached, or even before then, optionally in portions.

When dyeing cellulose fibers according to the bazing method, it can be padded at room temperature or at an elevated temperature, dried and then fixed by steaming or dry heat.

When printing is carried out on cellulose fibers, it can be printed in one phase, e.g. with a printing paste containing baking soda or other acid condensing agents, and then steamed at 100-160°C, or in two phases, e.g. Printing can be carried out by printing with an acidic or weakly acidic printing paste, passing it through a hot alkaline bath containing an electrolyte, or overbagging with a bagging liquid containing an alkaline electrolyte, followed by steaming or dry heat treatment.

Thickening agents or emulsifiers, such as, for example, sodium alginate or starch ethers, are used in the printing pastes, if desired in combination with customary printing auxiliaries and/or dispersants, such as, for example, urea.

Suitable acid binders for fixing the dyes of the invention on cellulose fibers are, for example, water-soluble basic salts of alkali metals or alkaline earth metals with inorganic or organic acids or compounds which liberate alkali upon heating. Particular mention may be made of alkali metal hydroxides and alkali metal salts of weak to medium strength inorganic or organic acids, of which soda salts and potassium salts are particularly preferred. Examples of such acid binders include caustic soda, caustic potash, sodium bicarbonate, sodium carbonate, sodium formate, potassium carbonate, primary, secondary, or tertiary sodium phosphate, sodium silicate, sodium trichloroacetate, and the like.

The dyeing of synthetic and natural polyamide and polyurethane fibers is carried out first by exhaustion under pH control from an acidic or slightly acidic dye bath, and then by changing to a neutral or even alkaline pH value for fixation. I can do it. Dyeing is usually carried out at a temperature of 60 to 120°C, but in order to achieve level dyeing properties, conventional leveling agents, such as condensation of cyanuric chloride and 3 times the molar amount of aminobenzenesulfonic acid or aminonaphthalenesulfonic acid, are used. It is also possible to use products or, for example, addition products of stearylamine and ethylene oxide.

The composition of the present invention is characterized in that it exhibits excellent performance in dyeing and printing textile materials. Particularly suitable for dyeing cellulose fiber materials, with good light fastness and sweat resistance, sunlight resistance, moisture resistance, such as washing resistance, peroxide washing resistance,
Sweat resistance, chlorine resistance, acid hydrolysis resistance and alkali resistance,
Furthermore, it has good abrasion resistance and ironing resistance.

In addition, it has excellent build-up properties, solubility, especially alkaline bath solubility, level dyeing properties, and wash-off properties, as well as good exhaustion and fixation properties, and stable quality that is not affected by fluctuations in dyeing temperature or dye bath ratio. It is characterized by the fact that dyed products can be obtained.

Another characteristic of the dyed product is that there is little discoloration during fix treatment or resin processing, and there is little change due to contact with basic substances during storage.

Hereinafter, the present invention will be explained in detail with reference to Examples.
