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

Abstract

The invention provides a composition of blue to black disperse dyes. The dyes mainly comprise the ingredients in parts by mass of 20-85 parts of at least one component A of which the structure is shown in the formula (I), 5-50 parts of at least one component B of which the structure is shown in the formula (II), and 1-55 parts of at least one component C of which the structure is shown in the formula (III). The composition of the disperse dyes disclosed by the invention can supply and dye in a micro-pelletized liquid state, a paste state or a powder state which is dried by a spray drying process and the like, and a granular state after being commercialized. When the composition of the disperse dyes disclosed by the invention dyes the hydrophobic fiber materials, each dye performance and the color fastness are excellent; and the blue to black fabrics (I), (II) and (III) can be obtained by adjusting the ratio of different components.

Description

(1) Technical field [0001] The invention relates to a blue to black 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] Blue-black series disperse dyes are the most widely used varieties of disperse dyes. C.I. Disperse Orange 76 is often blended with C.I. Disperse Violet 93 and C.I. Disperse Blue 291:1 to obtain excellent performance due to its excellent color fastness and color matching performance. Blue and black series disperse dyes. 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 ...
