Description
Technical field
The present invention relates to a kind of reactive dye compositions and, in the tint applications of filamentary material, particularly, the present invention relates to a kind of navy blue reactive dye composition and the tint applications on filamentary material thereof.
Background technology
The present invention relates to a kind of navy blue reactive dye composition, by compound synergic, thereby significantly improve its tint applications performance and dyefastness.
One of component of the navy blue reactive dye composition the present invention relates to is a kind of copper-containing metal Jia Za class (Formazan) dyestuff.
Hoechst company in 1986 delivers patent US4607098 and discloses following structure Jia Za type reactive dyestuffs and synthetic method thereof.
This dye structure is different from Hoechst company and delivers the structure of the disclosed Jia Za of patent US4336190 type reactive dyestuffs in nineteen eighty-two.
The structure difference of dyestuff m and dyestuff n is the difference that it becomes number of rings.The former is the dicyclo type, and latter is tricyclic.This patent points out, dicyclo Xing Jia Za type reactive dyestuffs have good tint applications performance.Commendable, the synthetic cost of dyestuff m is far below dyestuff n.
Since tricyclic Jia Za type reactive dyestuffs self-discovery, be subject to the attention of dyestuff circle always.Numerous research shows ， Jia Za type reactive dyestuffs, beautiful in colour, is far superior to conventional azo reactive dye.Compare ， Jia Za type reactive dyestuffs with anthraquinone type with triphendioxazine type reactive dyestuffs and there is the better and same consistency of dying of other color and luster dyestuffs.
The further development research of dicyclo Xing Jia Za type reactive dyestuffs, be not subject to due attention.
Last century end, Korea S Kyung-In Synthetic Corporation delivered the new structure that patent US5858026 discloses dicyclo Xing Jia Za type reactive dyestuffs in 1999.Its general formula is:
Korean Patent KR20030094982 and KR20040031792 disclose dicyclo Xing Jia Za type reactive dye compositions.This binomial patent report, dicyclo Xing Jia Za type reactive dyestuffs and tricyclic Jia Za type reactive dyestuffs blending, or the inner diverse structure blending of dicyclo Xing Jia Za type reactive dyestuffs, can further improve application performance and some dyefastness of dyestuff.
Up to now, the further further investigation to dicyclo type first Za type reactive dyestuffs, not yet be seen in patent report.
The inventor thinks after having verified by lot of experiments the related content that Korean Patent KR 20030094982 and KR 20040031792 announce, the inner isomery blending of dicyclo Xing Jia Za type reactive dyestuffs and dicyclo Xing Jia Za type reactive dyestuffs and tricyclic Jia Za type reactive dyestuffs carry out blending, really can improve in varying degrees certain tint applications performance.
But practice shows, the reactive dye compositions that Korean Patent KR20030094982 and KR20040031792 provide or miscellany, as the commercial dye kind, the real difficulty of its overall application performance meets the requirement of current printing and dyeing industry.
The inventor is by research trial in earnest, find pleasantly surprisedly, in the miscellany formed at general formula (1) dyestuff and general formula (2-A) dyestuff and/or general formula (2-B) dyestuff, add a kind of disazo dyes kind of copper metal complex of the same type and carry out blending as the 3rd component, can obtain unexpected pleasurable effect.
The structure of the disazo dyes kind of the copper-containing metal that the inventor adopts is as shown in general formula (3).It is blue to grey black that the color and luster of this class dyestuff is.
The time that this class dyestuff is disclosed in patent early.At first the patent of delivering is:
GB?1162144(1969)(Hoechst)、DE?1544538(1970)(Hoechst)。Dyestuff is good at the light fastness excellence.Hewlett-Packard Commpany delivers the at first dye component using this class application as ink for ink-jet print of patent GB 2318798 (1997).Other patent is also announced this reactive dyestuffs kind can make ink for ink-jet print with matching stain, substantive dyestuff blending.
, though dyestuff has excellent dyefastness, there is defect in general formula (3) in dyeing keratin-fiber, and for example level-dyeing property and enhancing rate are to be improved.Bright and lustrous degree has much room for improvement.
The inventor's test practice shows, of the present invention by the dye composition navy blue reactive dye composition that blending forms by a certain percentage shown in dye composition shown in dye composition shown in one or more general formulas (1), one or more general formulas (2-A) or general formula (2-B) and one or more general formulas (3), take in the length of its component dyestuff concurrently, its application performance significantly increases and improves.
Navy blue reactive dye composition of the present invention is with low cost, have excellent dyefastness, adjustable coloured light and good enhancing rate, degree of fixation and other color and luster reactive dyestuffs are with the consistency of dying, therefore, there is wide development space as commercial dye.
The blending data of the copper-containing metal bi-azo active dye shown in general formula (3), can consult following patent:

The data of relevant prompting ternary mixture provided by the present invention or composition, be not seen in the patent report.
Summary of the invention
The inventor, by experimental study, is surprised to find the blue active dye compound of the blue active dye compound, one or more general formulas (2-A) or general formula (2-B) expression that contain one or more general formulas (1) and mean and the dark blue dye composition of the black-and-blue reactive dye compound that one or more general formulas (3) mean and has very excellent dyeing behavior and every fastness.
What be worth proposition is, the tint applications performance of navy blue reactive dye composition of the present invention and every dyefastness, take in the length that it forms the characteristic of dyestuff concurrently, make up some defect that it forms dyestuff, navy blue reactive dye composition of the present invention, not only keep its good dyefastness that forms dyestuff, and obvious improvement all occurs in its level-dyeing property, enhancing rate, consistency.Navy blue reactive dye composition of the present invention, cost of manufacture is cheap, can form three primary colors with conventional red, yellow dye and use.Can predict, navy blue reactive dye composition of the present invention has wide prospects for commercial application.
