Abstract
The invention discloses a dispersed azo dye mixture, a product thereof, and a use of the product in printing and dyeing of hydrophobic synthetic materials. The mixture and the product contain at least one compound represented by formula (I) and at least one compound represented by formula (II) and/or formula (III), and substituent groups in the above formulas are defined as in the specification. The mixture and the product are especially useful in the printing and dyeing of hydrophobic synthetic materials.
Description
Technical field
The present invention relates to dye field, is exactly a kind of Dispers ozoic dyestuff mixture and goods thereof and the purposes for printing hydrophobic synthetic materials thereof.
Background technology
The serial kind maximum as usage quantity in deep color dispersion dyes of blue-black, C.I. DISPERSE ORANGE 30 200 76 is because of its colour fastness excellence, and colorant match excellent property, normal and C.I. 63 ,DIS,PER,SE ,Vio,let, 63 93, C.I. EX-SF DISPERSE BLUE EX-SF 300 291:1 blending obtain the blue-black series dispersed dye of excellent property.But because C.I. DISPERSE ORANGE 30 200 76 under given conditions can cracking and produce harmful arylamine, human body is produced irritated, therefore by C.I. DISPERSE ORANGE 30 200 76 blending blue-black series dispersed dye be classified as prohibitive dye by European Union member countries, seek environment-friendly type, colour fastness excellence blue-black series dispersed dye become the task of top priority.Patent CN102702790A discloses and is undertaken composite by novel orange structure replacement C.I. DISPERSE ORANGE 30 200 76, can obtain new disperse black dye composition, but this disperse black dye composition particularly still has the space promoted further in washing fastness in dyeing behavior.Along with the minimizing of monogenetic dyestuff mechanical development and the limitation in deep colour dyeing thereof, the compound synergic between dyestuff and dyestuff has become trend and the emphasis of industry research in recent years.GB 1576063A discloses a kind of blue, find in research to adopt this blueness as black or navy colorant match component, there is very outstanding performance in dyeing behavior and washing fastness, can be used as a kind of novel black or navy dye goods, there is very good application prospect.
