Color formers are extensively used in thermochromic systems for textiles, but their light fastness properties are poor. The improvement of light fastness is therefore being sought at the present time. Various kinds of stabilizers have been synthesized to prolong the life of colored species derived from color formers. The retarding effect of these compounds towards photofading was investigated on cellulose. It was found that the UV absorbers bearing the groups capable of acting as an amphoteric counter-ion play very important role in improving the light fastness of colorants for thermochromic textiles.Interest in the chemistry of natural colors has also increased in recent years, particularly with the increased use of naturally occurring pigments. Various kinds of phenyl ester compounds were synthesized and their protective effects against photofading of natural colors, Safflower Red Carthamin and Gardenia Blue, were examined on solid states. The application of simple UV absorbing compounds was not necessarily useful for improving the light fastness of natural colors. However, Phenyl ester UV absorbers bearing a singlet oxygen quencher, nickel sulfonate group, almost perfectly suppressed the photofading rates of these colors.Protection of the environment and human health is now perceived as more important than the profitability and efficiency of a business. The antimicrobial activity of these UV absorbing materials was therefore investigated. None of UV cutting materials developed in this study showed activity against either bacteria. Accordingly, the successful technique for improving light fastness of natural colors discovered here was safe for the environment and human health.

成色剂广泛应用于纺织品的热致变色体系，但其耐晒牢度性能较差。因此，目前正在寻求提高耐晒牢度的方法。合成了多种稳定剂，以延长成色剂衍生的有色物的寿命。考察了这些化合物对纤维素光褪色的延缓作用。研究发现，含有两性反离子基团的紫外线吸收剂在提高热致变色织物着色剂的耐光性方面起着非常重要的作用。近年来，人们对天然色素化学的兴趣也有所增加，特别是随着天然色素的使用增加。合成了多种苯酯类化合物，并考察了它们对天然色素红花红色素和栀子蓝在固态条件下的光褪色保护作用。应用简单的紫外线吸收化合物并不一定有助于提高天然色素的耐晒牢度。然而，含有单线态氧猝灭剂镍磺酸盐基团的苯酯紫外线吸收剂几乎完全抑制了这些颜色的光褪色速率。保护环境和人类健康现在被认为比企业的盈利和效率更重要。因此，我们研究了这些紫外线吸收材料的抗菌活性。在这项研究中开发的紫外线切割材料没有显示出对这两种细菌的活性。因此，这里发现的提高天然色素耐光性的成功技术对环境和人类健康是安全的。
