preparation example 1

[0050] Take 1mol of 2-(4'-diethylamino-2'-hydroxybenzoyl)-benzoic acid and 1mol of 2-diethylamino-4-hydroxyl-6-methyl-pyrimidine in the presence of 10mol of acetic anhydride under reflux for 4 hours, cooled, the reactant was poured into ice water, neutralized with sodium hydroxide to produce a precipitate, filtered, washed with water, dried to obtain a crude product, then recrystallized in cyclohexane, and decolorized with activated carbon, The target product A1 was obtained with a yield of 95.4% and a melting point of 176-177°C.

[0051]

preparation example 2

[0053] In addition to replacing 2-diethylamino-4-hydroxyl-6-methyl-pyrimidine with 2-dimethylamino-4-hydroxyl-6-methyl-pyrimidine, it was prepared in the same manner as in Preparation Example 1 Example 2, to obtain compound A2 with a yield of 97.2% and a melting point of 182-183.5°C.

[0054]

preparation example 3

[0056] Divide by 2-(4'-dimethylamino-2'-hydroxybenzoyl)-benzoic acid replacing 2-(4'-diethylamino-2'-hydroxybenzoyl)-benzoic acid and divide by 2 -Dimethylamino-4-hydroxyl-6-methyl-pyrimidine replaced 2-diethylamino-4-hydroxyl-6-methyl-pyrimidine, and Preparation Example 3 was carried out in the same manner as Preparation Example 1, Compound A3 was obtained with a yield of 96.7% and a melting point of 179-180.4°C.

Abstract

The invention relates to a color-changing agent applicable to textile fabrics and in particular relates to a color-changing agent applicable to textile fabrics and a preparation method of the color-changing agent. The color-changing agent comprises a silicon-titanium sol body, a light stabilizer, an antioxidant and a color-changing dye. The color-changing agent applicable to textile fabrics is reversible in thermochromism performance, strong in fastness, excellent in heat and light stabilizer and good in industrial application prospect and potential.

Description

technical field [0001] The invention relates to a discoloration agent for textile fabrics, in particular to a discoloration agent for textile fabrics comprising silicon-titanium sol, light stabilizer, antioxidant and discoloration dye and its preparation method, which belongs to functional dye field. Background technique [0002] With the development of science and technology and the improvement of people's living standards, people's aesthetics have also changed, and they show different needs from traditional ones in clothing, food, housing, transportation and other aspects. The emergence of color-changing textiles meets people's individual needs. With the help of modern high-tech, the color or pattern of textiles shows a change from conventional "static" changes with changes in light, temperature, and dryness. For the looming "dynamic" effect. Since this color change is caused by the fabric being "automatically" changed by external stimuli, it is called an intelligent col...
