Monoazo compounds and dyeing or printing methods using the same

The present invention relates to an improved novel monoazo compound which is suitable for dyeing and printing materials containing a hydroxyl group and/or amide group, particularly materials such as cellulose fiber, natural or synthetic polyamide fiber, polyurethane fiber, leather, and mixed fibers containing any materials of them and which is capable of giving dyed materials having good fastness to light and humidity. The present invention also relates to dyeing or printing methods using the monoazo compounds.
Heretofore, various reactive dyes have been known and they have widely been used in the field of dyeing and printing of fiber materials. For example, a monoazo compound having a vinylsulfon reactive group in the molecular structure and its use as the reactive dye are known.
However, the current technical level in the field of the reactive dye is not yet satisfactory in view of high-level requirements for dyeability and for fastness of the dyed product. That is, a known reactive dye is not necessarily sufficient in dyeing performances such as build-up properties, and fastness such as fastness to humidity of the dyed product. Further, such a known reactive dye cannot give sufficient dyeing performance and sufficient fastness simultaneously with maintaining good balance of them. Therefore, further improvement has been desired.
The present inventors have studied intensively for the purpose mentioned above. As a result, they found novel compounds which can widely satisfy essential elements to be required for the dye. Thus, the present invention has been accomplished.

Compound I of the present invention has a fiber reactivity, and it can be used for dyeing or printing a hydroxyl group-containing material or a carbonamide group-containing material. It is preferred that the material is used in the form of a fiber material or a mixed material thereof. The hydroxyl group-containing material can be natural or synthetic hydroxyl group-containing materials, such as cellulose fiber material, a regenerated product thereof and polyvinyl alcohol. As the cellulose fiber material, cotton or other vegetable fiber such as linen, flax, jute and ramie fiber is preferred. Examples of the regenerated cellulose fiber include viscose staple and filament viscose.

The. compound of the present invention can be dyed or printed on the above-described materials, particularly above-described fiber materials, by the method according to their physical and chemical properties.
For example, when the cellulose fiber material is dyed, the dyeing is carried out at a comparatively low temperature in the presence of sodium carbonate, tribasic sodium phosphate, sodium hydroxide, etc. by optionally adding neutral salts such as mirabilite or sodium chloride and by using dissolving auxiliaries, penetrating agents or leveling agents in combination, if desired. The neutral salt which accelerates adsorption of a dye can be added after or before the temperature reached a substantial dyeing temperature, and it can also be added in several portions. When the cellulose fiber material is dyed according to a padding method, the padding is carried out at room temperature or elevated temperature and, after drying, the dye can be fixed by steaming or dry heating.
When the cellulose fiber material is printed, the printing can be carried out in one phase, for example, by using a printing paste containing sodium bicarbonate and other acid binding agent, followed by steaming at 95.degree. to 160.degree. C. or it can be carried out in two phases, for example, by using a neutral or weak acid printing paste, followed by passing through a hot electrolyte-containing alkaline bath or overpadding in an alkaline electrolyte-containing padding solution and further steaming or dry heating treatment. Sizing agents or emulsifiers such as sodium arginate and starch ether are used as the printing paste, and normal printing auxiliaries and/or dispersants such as urea may be optionally used in combination.
The acid binding agent suitable for fixing the compound of the present invention on the cellulose fiber material can be, for example, hydroxides of alkaline metals, water-soluble basic salts of alkaline or alkaline earth metals and inorganic or organic acids, or compounds which liberates an alkaline in a state of heating. Hydroxides of alkaline metals and alkaline metal salts of weak or middle inorganic or organic acids are preferred. Among them, hydroxides of sodium or potassium, sodium salt and potassium salt are particularly preferred. Examples of the acid binding agent include sodium hydroxide, potassium hydroxide, sodium bicarbonate, sodium carbonate, sodium formate, potassium carbonate, monobasic-, dibasic- or tribasic sodium phosphate, sodium silicate and sodium trichloroacetate.
The dyeing of a synthetic or natural polyamide or polyurethane fiber material can be carried out by firstly adsorbing from an acid or weak acid dye bath while controlling the pH value, and changing the pH value to a neutral or alkaline pH value so as to fix the dye. The dyeing can be normally carried out at a temperature of 60.degree. to 120.degree. C. In order to accomplish the leveling, there can be used a normal leveling agent such as condensation product of cyanuric chloride and 3-fold mol parts aminobenzenesulfonic acid or aminonaphthalenesulfonic acid, or addition product of stearylamine and ethylene oxide.
The compound of the present invention imparts a red or rouge color tone on the fiber material, but it can be optionally used in combination with other dye so as to obtain the other desired color tone. In this case, the dye to be mixed is not specifically limited, and any reactive dye can be used.
