(Prior art) Usually, many of the various textile products and leather products are colored with pigments, and the coloring can be done using direct dyes or dyes depending on the nature of the substrate.
Acidic dyes, disperse dyes, reactive dyes, etc. are appropriately selected and used. When dyed fibers or dyed leather dyed with these dyes are exposed to sunlight or artificial light such as indoor fluorescent lights, the coloring pigments fade or change color.

557゜ (Problem to be solved by the invention) Recently, in this field, the level of demand for improving light fastness has been increasing, and the above-mentioned conventional technology is unable to meet the demand because it does not have a large effect on preventing fading. However, there are also cost constraints, and it is desired to develop higher performance photostabilizers and to make them more robust against light exposure through technology with lower running costs.

The problems to be solved by the present invention are, firstly, whether it is possible to significantly improve the light fastness of dyed pigments with simple operations and increase the added value of dyed fibers and dyed leather; 2. Although it has excellent physical properties such as clarity, heat resistance, and abrasion resistance, it has only poor light resistance, so it has not been used much in the past, but it has been put into practical use by adding a light stabilizer. The question is whether it is possible to improve the quality of dyes that can be used, expand the scope of use of these low-quality dyes, and contribute to reducing the cost of dyed products.

The light resistance of dyed leather and dyed fibers may be improved when treated with inorganic salts such as dichloride monochloride or cobalt chloride, but this is not due to the stabilization of dye molecules through metal chelation. This is a well-known fact. The photostabilizer according to the present invention is an anti-fading agent based on a new principle of deactivating active singlet oxygen, which is deeply involved in photobleaching of dyes, and has a different photostabilization mechanism from inorganic salts. It is.

Cotton fabrics dyed using dyes No. 37 and Direct Red 39 in a conventional manner (dyeing concentration: 3% 0.wf) were immersed in a light stabilizer solution for 10 minutes. After air-drying, the cotton cloth, which had been ironed to remove wrinkles, was exposed to carbon arc lamp light in a fading tester for 20 hours, and the color difference ΔE〆ab before and after the light irradiation was measured. Table 1 shows the results. Aromatic nickel sulfonic acid salt light stabilizers such as nickel benzenesulfonate, nickel tri-toluenesulfonate, nickel mesitylenesulfonate, nickel α-naphthalenesulfonate, and nickel 1,5-naphthalenedisulfonate according to the present invention. The color difference values of cotton dyed fabrics treated with organometallic complex-based light stabilizers such as di- and 2.7-kel dialkyldithiocarhamates and nickel bisdithiobenzyl are smaller than those of untreated standard dyed fabrics, and the color difference is smaller than that of untreated standard dyed fabrics. It can be seen that photobleaching of the dye is significantly suppressed.

(Margins below, continued on next page) Example 4 Dyed leather dyed with Acid Yellow 42 (standard dyeing concentration M) was treated with 2% Nisokel dialkyldithiocarhame F, nickel bisdithiobenzyl, and 2-mercaptohenzothiazole. After spraying an aqueous solution or an ethanol solution of Nisokel salt or Hensensulfonic acid nickel salt with a spray gun 2 to 8 times, the sample was irradiated with carbon arc lamp light for 10 to 30 hours. The change in [(△E'ab of treated dyed leather)/(△E'ab of standard dyed leather) x 100] was used as a guideline for evaluating the improvement of light fastness.
It is shown in Figure 1. As an example of the results, when treated with a 2% solution of 2-mercabutobenzothiazole disoquer salt 2.5.8 times, 47.

When other compounds were used, it was found that this value decreased as the number of sprays, that is, the amount of coating increased, and the light fastness was improved. In addition, these effects do not decrease even after 30 hours of prolonged light irradiation, indicating that these organic nickel complexes and aromatic sulfonic acid nickel salt compounds are extremely effective in improving the light fastness of dyed leather products. It appears to be effective. Furthermore, the texture of dyed leather treated with these nickel compounds was also improved, which shows how effective it is as a quality improver for dyed leather.

In addition, standard dyed leather (for comparison) was obtained by dyeing in a dye bath containing no light stabilizer. When the thus obtained dyed leather was irradiated with carbon arc lamp light for 10 hours, the color difference value ΔE'ab of the standard dyed leather was 8.4, whereas that obtained from the dyeing bath containing NBS or NMS was For dyed leather, the values were 4.9 and 3.5, respectively. That is, it is also possible to improve the light fastness of dyed leather by including a light stabilizer in the dyeing bath solution in advance and applying it at the same time as the dyeing process.

Regarding rubamic acid complexes, almost the same effect was observed even when the alkyl group was changed to a methyl group or an ethyl group, and even when the metal type of the complex was changed to zinc or cobalt, the light resistance was improved. Improvement can be obtained. If the light stabilizer of the present invention is processed, it is possible to further improve the quality of practical products, and although other pigment physical properties are conventionally excellent, only light resistance is insufficient, so it cannot be put into practical use. It is now possible to actually use low-quality and inexpensive dyes that were previously unavailable, and the effects of light stabilizers are truly great, such as the ability to select trendy colors and reduce costs.

Furthermore, as shown in Example 4, when the light stabilizer of the present invention is applied to dyed leather, it not only has the effect of preventing fading, but also has a secondary effect that delays hardening of the leather and maintains and improves texture characteristics. The present invention makes a great contribution to this field, as it exhibits various effects.
