Abstract

The invention discloses a high-fastness blue-to-black color disperse dye composition and a dye product. The high-fastness blue-to-black color disperse dye composition comprises an ingredient A and an ingredient B. The ingredient A comprises one or more of compounds shown in the formula (I) and / or formula (II). The ingredient B comprises one or more of compounds shown in the formula (III). The mass percentage content of the ingredient A is in a range of 30-90% and the mass percentage content of the ingredient B is in a range of 10-70%. The blue-to-black color disperse dye product contains the blue-to-black color disperse dye composition shown in the claim 1 and an assistant, and a weight ratio of the assistant to the blue-to-black color disperse dye composition is 0.2-5: 1. The high-fastness blue-to-black color disperse dye composition and dye product are used for hydrophobic fiber material dyeing and have the characteristics of good lifting force, sublimation resistance, wear resistance and excellent washing fastness.

Description

(1) Technical field [0001] The invention relates to a blue to black disperse dye composition and a dye product, in particular to a high fastness blue to black disperse dye composition and a dye product suitable for printing and dyeing hydrophobic fiber materials. (2) Background technology [0002] In the quality inspection of textile color fastness, color fastness to washing is an important inspection item, and its test results are directly related to the overall color fastness of the fabric. Some dyes with poor color fastness can also cause different degrees of damage to the human body, so different organizations and countries have formulated corresponding standards to strictly limit the color fastness grades of clothing and home textiles. AATCC is the standard of the American Dyestuffers Association, which is quite different from the Chinese national standard (GB / T series) and international standard (ISO series). For example, the color fastness to washing of the same produ...
