Abstract
The invention relates to a high-light-fastness disperse black dye composition which comprises substances disclosed as structural formulae (I)-(VI). The proportion of different components is regulated to obtain the dark-blue-to-black dyes with favorable tones, favorable dispersity, high light fastness and other favorable properties.
Description
technical field [0001] The invention belongs to the field of dyes, in particular to a high-solarization disperse black dye composition. Background technique [0002] With the rapid development of polyesterfiber and the improvement of people's living standards this year, people pay more attention to sun protection work such as outdoor activities and cars, so there is an urgent need for a dye product with high light fastness in the sun to meet people's needs . This product should have high light fastness and excellent compatibility, so as to meet the needs of automotive tarpaulins, curtains, sun umbrellas and other products. [0003] At present, the common disperse black on the market is mainly composed of conventional dyes such as disperse orange 288, disperse orange 61, and disperse dark blue 291. The advantages of such conventional dyes are that they are stable and easy to dye, but their fastness is poor. Contents of the invention [0004] The object of the present inv...
