The anthraquinone compound (I) of the present invention is fiber-reactive and is useful for dyeing or printing hydroxyl group-containing and amide group-containing materials, preferably in a fibrous form or a mixed fibrous form.

The hydroxyl group-containing materials include natural or synthetic hydroxyl group-containing materials such as cellulose fiber materials, regenerated products thereof and polyvinyl alcohol. Examples of the cellulose fibers materials are cotton and other vegetable fiber such as linen, hemp, jute and ramie fibers. Examples of the regenerated cellulose fibers are viscose staple and filament viscose.

The amide group-containing materials include synthetic or natural polyamide and polyurethane. Examples of the materials, particularly in fibrous forms, are wool and other animal furs, silk, leather, polyamide-6,6, polyamide-6, polyamide-11 and polyamide-4.

The dyeing can be carried out in any manner suitable for the reactivity of the fiber reactive dye.

For example, cellulose fiber materials can be dyed using the anthraquinone compound of the present invention together with an acid binding agent such as sodium hydroxide, sodium carbonate, phosphates, silicates and sodium hydrogencarbonate in a manner which can be selected from those depending on the property of fibers and physical shape thereof. Examples of the manner applicable are exhaustion dyeing, printing, cold pad batch-up and other methods.

The exhaustion dyeing can be carried out at a relatively low temperature in the presence of an acid binding agent such as sodium carbonate, trisodium phosphate, sodium hydroxide and the like as well as a neutral salt such as sodium sulfate, sodium chloride and the like.

The printing can be carried out by printing the fiber materials with a printing paste containing a paste or emulsified paste such as sodium alginate, starch ether and the like, and an alkali agent such as sodium carbonate, sodium hydrogencarbonate, trisodium phosphate, sodium trichloroacetate and other alkaline or alkali-liberating agents such as potassium or alkaline earth metal salts corresponding to the above, if desired together with a conventional printing auxiliary agent such as urea or a dispersing agent, followed by drying and heat-treating, particularly in the presence of steam.

The cold pad batch-up dyeing can be carried out by padding the fiber materials with a padding liquor at ambient temperature, batching up and allowing the padded fiber materials to stand on a roller for 3 hours or more or over-night, followed by washing with water and drying. The padding liquor can be prepared in a conventional manner using an acid binding agent such as sodium hydroxide alone or a mixture of sodium hydroxide with sodium silicate, sodium carbonate or trisodium phosphate, and if desired, sodium sulfate or sodium chloride optionally together with a dissolution auxiliary agent such as urea and a penetrant.

The dyeing of natural or synthetic polyamide and polyurethane fiber materials can be carried out by performing exhaustion in an acid or weak acid bath, while controlling the pH value, and then making the bath neutral, or in some cases alkaline, to perform the fixation. The dyeing temperature ranges usually from 60.degree. to 120.degree. C. In order to achieve a level dyeing, there may be used a conventional level dyeing agent such as condensation product between cyanuric chloride and 3 times by mole of aminobenzenesulfonic acid or aminonaphthalene-sulfonic acid, or an addition product between stearylamine and ethylene oxide, and the like.

The present anthraquinone compound can be characterized by superior dye performance in the dyeing and printing of fiber materials, particularly cellulose fiber materials. For example, the present anthraquinone compound can exhibit high exhaustion and fixation percentages and superior build-up properties as well as superior level-dyeing and washing-off properties and high robustness so that a shade to be obtained is hardly affected by some changes in dyebath conditions such as dyeing temperatures, bath ratios, salt concentrations and the like.

Moreover, the dyed or printed products are excellent in fastness properties such as light fastness, perspiration-light fastness, perspiration fastness, acid-hydrolysis fastness, washing fastness, chlorine fastness and the like.

The present invention is illustrated in more detail with reference to the following Examples, which are only illustrative, but not limitative of the scope of the present invention. In Examples, parts are by weight.
