合成了2-羟基-4-甲氧基二苯甲酮-5-磺酸镍盐（MS-Ni）及其衍生物（DS-Ni），它们是含单线态氧猝灭基团的二苯甲酮型紫外线吸收剂，并研究了它们对某些染料在溶液中和固体上紫外光褪色的影响。测定了靛蓝染料（C. I.还原蓝1）、蒽醌染料（C. I.分散红15）和偶氮染料（C. I.酸性橙子20）在MS-Ni或DS-Ni存在下，无论是在溶液中还是在固体中，都有明显的缓蚀作用，而曙红（C. I.酸性红87）在固体上几乎不被抑制。研究了对甲苯磺酸镍和2，6-二叔丁基苯酚对染料光稳定性的影响。
Nickel salt of 2-hydroxy-4-methoxybenzophenone-5-sulfonic acid (MS-Ni) and its derivative (DS-Ni), benzophenone type UV absorber containing singlet oxygen quenching group, have been synthesized and its effects were examined on the photofading of some dyes in solution and on a solid with a UV irradiation. The rates of photofading of indigoid dye (C. I. Vat Blue 1), anthraquinonoid dye (C. I. Disperse Red 15) and azo dye (C. I. Acid Orange 20) were remarkably retarded in the presence of MS-Ni or DS-Ni not only in solution but also in a solid state, but that of Eosine (C. I. Acid Red 87) on a solid was suppressed scarcely. The effects of added Nickel p-toluenesulfonate and 2, 6-di-t-butylphenol on the photo-stability of dyes were also examined.
