Abstract

The invention discloses a mesothermal disperse blue dye composition, which comprises by weight: 73%-99% of component A, 1%-25% of component B and 0%-2% of component C. Wherein, the component A is a compound as shown in formula (1), the component B is one or more of the compounds shown in formula (2), and the component C is one or more of the compounds shown in formula (3). The mesothermal disperse blue dye composition provided in the invention has bright color, good alkali resistance, good color fastness to light, and great lifting power, and is obviously higher than disperse blue 56# in terms of sublimation fastness and washing fastness. In addition, the mesothermal disperse blue dye composition has good comparability and strong color rendering capability, so that the usage amount of the dye can be obviously reduced, thus reducing cost.

Description

technical field [0001] The invention relates to a disperse dye composition, in particular to a mid-temperature disperse blue dye composition suitable for polyester fiber dyeing and printing. Background technique [0002] When dyed with anthraquinone type disperse blue 56#, the shade is bright, it can withstand weak alkali, and its light fastness is better, so it has become a widely used main color dye, but its color development is low, and it pollutes the environment. The cost is relatively high. high. Therefore, it is imperative to look for an environment-friendly blue disperse dye composition that is close to disperse blue 56# in shade and performance and can make up for the deficiency of disperse blue 56#. Contents of the invention [0003] The invention provides an environment-friendly disperse blue dye composition with medium temperature, bright color, good alkali resistance, good light fastness, high lifting power, high color giving power, low cost and good compatib...
