Alternatively, the cyanuric chloride or fluoride can be used in the course of the production of the organic dye capable of imparting the desired dye moiety. For example, cyanuric chloride can be subjected first to condensation with a coupling component, followed by coupling with & diazo component. Successively, the resulting halogenotriazine compound can be subjected to condensation with the aminobenzoylamine compound of the formula (III). In this manner, the triazine compounds of the present invention can be also produced.

The condensation reaction conditions are those known by the skilled in this art. After completion of the reactions, the desired triazine compound-containing reaction mixture may be subjected to salting-out in a conventional manner, demineralisation with a semipermeable membrane, evaporation such as spray-drying, if desired, with use of usual auxiliary agents such as stabilizing agents or dyeing improvers, to provide a pulverulent or liquid commercial product. The triazine compounds in accordance with the present invention may be in the form of a free acid or a salt of an alkali metal or alkaline earth metal, preferably in the form of sodium or potassium salt. The triazine compounds of the present invention are fiber-reactive and useful for dyeing or printing hydroxyl group-containing and amide group-containing materials. The materials are favorably in a 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 fiber materials 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 amide group-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 triazine compound by an exhaustion dyeing, padding including cold batch-up dyeing or printing method. 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 or sodium hydroxide if desired, using a neutral salt such as sodium sulfate or sodium chloride, together with a hydrotropic agent, a penetrant or a level dyeing agent. The neutral salt suitable for promoting the exhaustion may be added to a dye bath before or after temperature reaching a desired level for the dyeing, if desired, dividedly. The padding 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 cold batch-up dyeing can be carried out by padding the fiber materials with a padding liquor at ambient temperature, batching up and allowing them to stand on a roller for 3 hours or more or over night, followed by washing with water and drying. The printing can be carried out in a one-phase 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, followed by steaming at a temperature of 100° to 160°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 or starch ether may be used, if desired, together with a conventional auxiliary agent such as urea and/or 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 hydrogencarbonate, sodium carbonate, sodium formate, potassium carbonate, sodium dihydrogenphosphate, disodium hydrogenphosphate, trisodium phosphate, sodium silicate and sodium trichloroacetate. 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° to 120°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 aminobenzene-sulfonic acid or aminonaphthalenesulfonic acid, or an addition product between stearylamine and ethylene oxide. The present triazine compounds can be characterized by excellent dye performance in the dyeing and printing of fiber materials, particularly cellulose fiber materials. For example, the compounds can give dyed products excellent in light fastness, perspiration-light fastness, formalin 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 triazine compounds can also exhibit extremely excellent build-up, level-dyeing and washing-off properties and high solubility as well as high exhaustion and fixation percentages. Moreover, when used for the dyeing or printing, the triazine compounds can hardly be affected by changes in dyebath conditions such as temperatures, pH, amounts of inorganic salts and bath ratio, so that a dyed or printed product with a constant quality can be obtained with superior reproducibility. Further, particularly when applied for the dyeing by the cold batch-up dyeing method, the triazine compounds can exhibit excellent build-up property and alkali stability (almost no hydrolysis by the action of the alkali agent) and almost no difference in the depth and shade appears between the dyed products obtained by fixing at 25°C and at a lower temperature than that. The present invention is illustrated in more detail with reference to the following Examples, which are only illustrative, but not limitative. In Examples, all parts and % are by weight. Example 1 1-Amino-8-hydroxy-7-(o-sulfophenylazo)-3,6-naphthalenedisulfonic acid (50.4 parts) was dissolved in water (500 parts), and cyanuric chloride (18.5 parts) was added thereto. The mixture was stirred at 0° to 5°C, while controlling the pH within 2 to 3, to complete a first condensation. To this reaction mixture, an aqueous solution of 1-(4′-aminobenzoylamino)benzene-3-β-sulfatoethylsulfone (40 parts) was slowly added, and the resulting mixture was stirred at 40° to 50°C, while controlling the pH within 4 to 5, to complete a second condensation. The reaction mixture was mixed with sodium chloride to precipitate crystals. The crystals were separated on a filter, washed and dried to obtain a triazine compound of the following formula in the free acid form. Examples 2 to 31 Example 1 was repeated, provided that the first and second condensation reactions were carried out using the compound of the formula (IV) as shown in a second column of the following table, cyanuric chloride or fluoride as shown in a third column, in which Cl and F mean cyanuric chloride and cyanuric fluoride, respectively, and the compound of the formula (III) as shown in a fourth column, thereby obtaining the corresponding triazine compound, which was used for dyeing cellulose fibers to give a dyed product of a shade as shown in a fifth column. Dyeing Example 1 The triazine compounds (each 0.3 part) obtained in Examples 1 to 31 were respectively dissolved in water (200 parts). Sodium sulfate (10 parts) and cotton (10 parts) was added thereto, and the dyebath was heated to 60°C. 20 Minutes thereafter, sodium carbonate (4 parts) was added thereto, and dyeing was continued for 1 hour at that temperature. Thereafter, the cotton taken out of the bath was washed with water and soaped to obtain a dyed product excellent in fastness properties with superior dye performance. Even when the dyebath conditions including temperatures, bath ratio and amount of the inorganic salt were varied to some extent, a dyed product of invariable quality was obtained with superior reproducibility. Dyeing Example 2 Composition of color paste Each triazine compound obtained in Examples 1 to 31 5 parts Urea 5 parts Sodium alginate (5%), thickener 50 parts Hot water 25 parts Sodium hydrogencarbonate 2 parts Balance (water) 13 parts Mercerized cotton broad cloth was printed with the color paste of the above composition, pre-dried, steamed at 100°C for 5 minutes, washed with hot water, soaped, again washed with hot water and dried, thereby obtaining a printed product excellent in fastness properties with superior dye performance. Dyeing Example 3 Each triazine compound obtained in Examples 1 to 31 (25 parts) was dissolved in hot water, and the solution was cooled to 25°C. 32.5% Aqueous sodium hydroxide solution (5.5 parts) and 50°Be′ water glass (150 parts) were added thereto, and water was added to make the whole 1000 parts at 25°C to obtain a padding liquor. Immediately thereafter, cotton cloth was padded with the padding liquor and batched up, and the cloth wrapped tightly with a polyethylene film was allowed to stand in a room kept at 20°C. Above manner was repeated to obtain a padded cotton cloth, which was then wrapped tightly with a polyethylene film, and allowed to stand in a room kept at 5°C. Both cloths were allowed to stand for 20 hours, and thereafter washed with cold water and then hot water, soaped with a boiling detergent, washed with cold water and then dried. There was observed almost no difference in their color shade and depth between the dyed products obtained after standing at 5°C and 20°C each for 20 hours. In this cold batch-up dyeing method, each triazine compound was found to have superior build-up property.
