Dyestuff A shown in the formula (I) is preferably one or more in the following compounds:
Dyestuff B shown in the formula (II) is preferably one or more in the following compounds:
Described composite active dye is that dyestuff A, one or more weight percentage of 1~99% are that 1~99% dyestuff B forms by one or more weight percentage.
Composite active dye of the present invention can prepare with ordinary method, for example generally uses single dyestuff A of mechanically mixing and B.This single dyestuff can powdery, the aqueous solution form of granular, resulting solution or each dyestuff exists, and wherein can add auxiliary agent commonly used, as Sodium sulfate anhydrous.min(99) etc.Single dyestuff A, B can describe it respectively as patent CN1103416, patent JP56-103249 with known method preparation.
The preparation that composite active dye of the present invention can be used as powdery or granular solid-state form, liquid form exists, they generally comprise water-soluble and the habitual electrolytic salt of fibre-reactive dyes particularly under solid-state form, such as sodium-chlor, Repone K and sodium sulfate etc., and can further comprise the auxiliary agent that commercial dye is habitual.
When single dyestuff A, B are mixed with the form assembly of resulting solution, separating composite active dye of the present invention from resulting solution can carry out with general known method, for example using ionogen (as sodium-chlor or Repone K) from reaction medium dyestuff to be saltoutd leaches, or with mixing solutions evaporation, spraying drying, at this moment, can add the commercialization usual auxiliaries, as Sodium sulfate anhydrous.min(99) (industrial sulphuric acid sodium) etc.
Composite active dye of the present invention is suitable for the dyeing and the stamp of filamentary materials such as most of hydroxyl or nitrogenous material, for example silk, leather, timber, tynex and trevira, cellulosic fibre material especially.Cellulosic fibre material if any native cellulose fibre as cotton, flax, fabric, hemp fibre, Mierocrystalline cellulose and regenerated cellulose.Composite active dye of the present invention also is suitable for the dyeing or the stamp of the BLENDED FABRIC of hydroxyl fiber, as mixture cotton and trevira or tynex.Dyestuff of the present invention is particularly suitable for dyeing or the stamp of cellulosic fibre material cotton.
Composite active dye of the present invention has high reaction activity, good fixation ability and dye uptake.Can dye or stamp to above fabric by the known utilisation technology of water-soluble dye, particularly fibre-reactive dyes, obtain bright Huang to hues of orange, sun-resistant fastness, fastness to rubbing, the fabulous dyeing and weaving thing of washing fastness.
(4) embodiment
Below in conjunction with specific embodiment the present invention is further described, but protection scope of the present invention is not limited to this.
Generally be with the form of its salt preparation and isolating according to the described compound of structural formula in an embodiment, preferred form is sodium salt or sylvite, and is used for dyeing with the form of its salt.Compound described in the embodiment can adopt known method, is synthesized with the form of free acid or the form of its salt similarly.Except as otherwise noted, following " part " is folding hundred weight parts.
Embodiment 1
Synthesizing of formula (I-1) dyestuff
At 61.1 parts of 7-(4-amino-2-urea groups-phenyl diazonium) naphthalene-1,3, the 6-trisulfonic acid receive and 400 parts of ice/water mixture in, adds 18.8 parts of cyanuric chlorides and pulled an oar 2 hours, 0~10 ℃ of controlled temperature, PH are less than 3, the hydrochloric acid of generation neutralizes by adding sodium bicarbonate.Drip in the above-mentioned reaction soln 18.8 parts of dissolvings good 2, the solution of 4-diamino benzene sulfonic acid and 150 parts of water is controlled PH5~7.5, the solution that generates is warming up to 32 ℃, and insulated and stirred 1.5 hours is surveyed terminal point with the TLC chromatography, terminal point to after be that coupling component cools to 15 ℃ with Generation Liquid, standby.30.3 part para-ester, promptly to (beta-sulfuric ester ethyl sulfonyl) aniline approach diazotization routinely in 150 portions of frozen water, in about 1.5 hours, this diazonium salt solution is added drop-wise to and carries out coupled reaction in the above-mentioned coupling component, 1~10 ℃ of controlled temperature, PH4~7, stirring reaction 3 hours.The dye solution desalination that generates is also dry, and what promptly get following formula (I-1) can dye cotton fibre flavous dyestuff.
