The monoazo compound (I) of the present invention can be produced in the following manners.
Cyanuric chloride or fluoride is subjected to first condensation with any one of the monoazo amine compound (II) or the arylamine (III), followed by second condensation with the remaining amine, thereby obtaining a desired monoazo compound of the following formula (I'), ##STR18## wherein D, X.sub.1, X.sub.2, R, A and Z are as defined above.
The first and second condensations can be carried out in an aqueous medium at a temperature ranging from 0.degree. C. to 30.degree. C., while controlling the pH within a range of 2 to 7, and at a temperature ranging from 20.degree. C. to 60.degree. C., while controlling the pH within a range of 3 to 7, respectively.
If desired, the monoazo compound (I') can be subjected to third condensation with the sulfoarylamine (IV), obtaining another desired monoazo compound of the following formula (I"), ##STR19## wherein D, X.sub.1, X.sub.2, Y.sub.1, R, A and Z are as defined above. The third condensation which may be conducted prior to the first or second condensation can be carried out in an aqueous medium at a temperature ranging from 60.degree. C. to 90.degree. C., while controlling the pH within a range of 3 to 6.
In another manner, cyanuric chloride or fluoride is subjected to first condensation with any one of the amine compound (V) or the arylamine (III), followed by second condensation with the remaining amine, obtaining an intermediate compound of the following formula (IX), ##STR20## wherein X.sub.1, X.sub.2, R, A and Z are as defined above.
The first and second condensations can be carried out in an aqueous medium at a temperature ranging from 0.degree. C. to 30.degree. C., while controlling the pH within a range of 2 to 7, and at a temperature ranging from 20.degree. C. to 60.degree. C., while controlling the pH within a range of 3 to 7, respectively.
Successively, the intermediate compound (IX) is subjected to coupling with a diazonium salt of the aromatic amine (VI), which can be produced in a conventional manner, in an aqueous medium at a temperature ranging from 0.degree. C. to 50.degree. C., while controlling the pH within a range of 4 to 8, whereby the desired monoazo compound (I') can be produced.
If desired, the monoazo compound (I') can be subjected to third condensation with the sulfoarylamine (IV) in the manner described above, obtaining another desired monoazo compound (I"). The third condensation may be conducted prior to the first or second condensation.
The desired monoazo compound can be also produced in the following manner.
Cyanuric chloride or fluoride is subjected to first condensation with any one of the phenylenediamine (VII) or the arylamine (III), followed by second condensation with the remaining amine.
The first and second condensations can be carried out in an aqueous medium at a temperature ranging from 0.degree. C. to 30.degree. C., while controlling the pH within a range of 2 to 7, and at a temperature ranging from 20.degree. C. to 60.degree. C., while controlling the pH within a range of 3 to 7, respectively.
Successively, the resulting condensate is subjected to reaction with diketene at a temperature ranging from 10.degree. C. to 50.degree. C., while controlling the pH within a range of 3 to 7, whereby the intermediate compound (IX) can be produced.
Then, the intermediate compound (IX) is subjected to coupling with the diazonium salt of the aromatic amine (VI) in the manner described above, whereby the desired monoazo compound (I') can be produced.
In the above manner, if the first condensation is carried out using the phenylenediamine (VII), the reaction using diketene may be conducted immediately after the first condensation.
If desired, the monoazo compound (I') obtained may be subjected to third condensation with the sulfoarylamine (IV), obtaining another desired monoazo compound (I"). Likewise, the third condensation may be conducted prior to the first or second condensation.
The monoazo compound (I), or a salt thereof, of the present invention has a fiber-reaction group, and can be used for dyeing (including printing) hydroxyl group- or nitrogen-containing materials, which are preferably in a fibrous form. The fiber materials may be blended products.
When applied for dyeing fiber materials, the monoazo compound (I) obtained can be used each alone or in a mixture of two different from each other. The mixture in a mixing weight ratio of 10:90 to 90:10 can be expected to exhibit more excellent dye performances.
The hydroxyl group-containing materials include natural or synthetic hydroxyl group-containing fiber materials such as cellulose fiber materials, regenerated products thereof and polyvinyl alcohol. Examples of the cellulose fiber materals are cotton and other vegetable fibers such as linen, hemp, jute and ramie fibers. Examples of the regenerated cellulose fibers are viscose staple and filament viscose.
The nitrogen-containing materials include synthetic or natural polyamide and polyurethane. Examples of the materials, particularly in the fibrous forms, are wool and other animal furs, silk, leather, polyamide-6,6, polyamide-6, polyamide-11 and polyamide-4.
The dyeing may be carried out in a suitable manner, which can be selected from conventional manners depending on the physical and chemical properties of said fiber materials.
For example, cellulose fiber materials can be dyed using the present compound by an exhaustion dyeing, padding or printing method.
The exhaustion dyeing method 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, if desired using a neutral salt such as sodium sulfate, sodium chloride and the like, optionally together with dissolving assistants, penetrants or level dyeing agents. The neutral salt which can be used for promoting exhaustion of the dye may be added to a dye bath at the time when a bath temperature reaches a level desired for dyeing, or prior thereto. Alternatively, the neutral salt may be added thereto dividedly.
The padding method can be carried out by padding the fiber materials at ambient temperature or an elevated temperature, and after drying, steaming or dry-heating the materials to perform the dye-fixation. The padding can be also carried out by a cold pad batch method.
The printing can be carried out in a onephase or two-phase manner. The one-phase printing may be conducted by printing the fiber materials with a printing paste containing an acid binding agent such as sodium hydrogencarbonate and the like, followed by steaming at a temperature of 100.degree. to 160.degree. C. The two-phase printing may be conducted by printing the fiber materials with a neutral or weakly acidic printing paste, and passing the materials through a hot alkaline bath containing an electrolyte or over-padding the materials with an alkaline padding liquor containing an electrolyte, followed by a steaming or dry-heating treatment.
For the preparation of the printing paste, a paste or emulsifier such as sodium alginate, starch ether and the like may be used, if desired, together with a conventional auxiliary agent such as urea and/or a dispersing agent.
The acid binding agent useful for fixing the compound of the present invention on the cellulose fiber materials includes water-soluble basic salts consisting of alkali or alkaline earth metals and inorganic or organic acids or compounds capable of liberating alkalis under heating conditions. Preferred are alkali metal hydroxides and alkali metal salts of inorganic or organic acids having a weak or medium strength. Particularly preferred are sodium salts and potassium salts. Examples thereof are sodium hydroxide, potassium hydroxide, sodium hydrogen carbonate, sodium carbonate, sodium formate, potassium carbonate, sodium dihydrogen phosphate, disodium hydrogen phosphate, trisodium phosphate, sodium silicate, sodium trichloroacetate and the like.
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 a condensation product between cyanuric chloride and 3 times by mole of aminobenzenesulfonic acid or aminonaphthalenesulfonic acid, or an addition product between stearylamine and ethylene oxide, and the like.
The present monoazo compound (I) can be characterized by excellent dye performances in the dyeing (including printing) of fiber materials, particularly cellulose fiber materials. For example, the compound can give a dyed product excellent in light fastness, perspiration-light fastness, wet fastness such as washing resistance, peroxide-washing resistance, chlorine resistance, chlorine bleaching resistance, perspiration resistance and acid-hydrolysis resistance, and alkali fastness, abrasion fastness and iron fastness. The compound can also exhibit excellent build-up, level dyeing and wash-off properties, favorable solubility and high exhaustion and fixation percentages. Moreover, the present monoazo compound (I) can hardly be affected by changes in a dyeing temperature and a dyeing bath ratio, so that a dyed product with a constant quality can be given with superior reproducibility.
As compared with those described in the aforesaid Published Unexamined Japanese Patent Application Nos. 12933/1978 and 112584/1981, the monoazo compound (I) of the present invention shows more excellent dye performances such as build-up property to give dyed products of a deeper color, and fastness properties, particularly light fastness, perspiration-light fastness and chlorine fastness.
