Problems solved by technology

However, because C.I. Disperse Orange 76 will crack under certain conditions to produce aromatic amines that are harmful to the human body, causing allergies to the human body, the blue and black series of disperse dyes blended by C.I. Disperse Orange 76 have been listed as banned dyes by EU countries It has become a top priority to seek environmentally friendly blue-black series disperse dyes with excellent color fastness
Patent CN102702790A discloses that a new type of orange structure is used instead of C.I. Disperse Orange 76 for compounding to obtain a new disperse black dye composition, but the disperse black dye composition still has room for further improvement in terms of dyeing performance, especially in terms of washing fastness

Abstract

The invention provides a dark azo type disperse dye composition mainly including 20 to 85 parts by mass of a component A (I), 5 to 50 parts by mass of a component B (II), 1 to 45 parts by mass of a component C (III) and 1 to 45 parts by mass of a component D ((IV-1) and / or (IV-2)). When the dark azo type disperse dye composition is applied in dyeing of hydrophobic fiber materials, each dyeing property and the color fastness especially the washing fastness are prominent. The dark azo type disperse dye composition is especially suitable for dyeing of polyester materials, has the characteristics of wide pH dependent range (dyeing at a pH value of 3.5 to 9.5), high coloring capacity, excellent lifting force and the like.

Description

(1) Technical field [0001] The invention relates to a dark azo-type disperse dye composition, in particular to a blue to black disperse dye composition suitable for printing and dyeing hydrophobic fiber materials. (2) Background technology [0002] The blue-black series is the most used variety among the dark disperse dyes. CI Disperse Orange 76 is often mixed with CI Disperse Violet 93 and CI Disperse Blue 291:1 due to its excellent color fastness and excellent color matching performance. Blue and black series of disperse dyes. However, because CI Disperse Orange 76 will crack under certain conditions to produce aromatic amines harmful to the human body and cause allergies to the human body, the blue and black series of disperse dyes blended by CI Disperse Orange 76 have been listed as banned dyes by EU countries It has become an urgent task to seek environmentally friendly, blue-black series of disperse dyes with excellent color fastness. Patent CN102702790A discloses that a ...
