発し、その改善が望まれていた。In addition, these fluorescent whitened polyamide fiber products come into contact with various wrapping papers and films during distribution and use, becoming contaminated and yellowing, or exposed to nitrogen oxides (NOx) in the atmosphere. Discoloration frequently occurs due to such factors, and an improvement has been desired.

と見なされる。The mechanism of this action is unknown, but it is presumed to be due to the chemical structure of these compounds, in which the sulfonic acid groups in the compounds adsorb to the terminal amino groups of the polyamide fabric through ionic bonds, and due to the synergistic action of both compounds. It is considered to be an indication of effectiveness.

良好であるが８度が乏しい。That is, when a polyamide fabric is treated and adsorbed with the compound (1) alone, it is possible to impart better light resistance of 8 degrees than when treated with a conventional fluorescent brightener, but it is insufficient. , and the yellowing prevention property is poor. On the other hand, when the compound (2) is treated and adsorbed alone, the yellowing prevention property is good but the 8 degree is poor.

著しく低下させる。Furthermore, when a commonly used fluorescent brightener is used instead of compound (1) used in the present invention and treated in combination with compound (2) used in the present invention, the yellowing prevention property is improved. However, when the 8 degree and light resistance are insufficient, and on the other hand, a commonly used anti-yellowing treatment agent is used instead of the compound (2) and treated in combination with the compound (1). is 8 degrees and the light resistance is slightly improved, but it is insufficient.
Moreover, when a water repellent treatment is applied as a subsequent processing, the water repellency is significantly reduced.
