Evaluation and Development of UV Ray Blocking Wears for Outdoor Sports
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.27 Vol.27】
Various kinds of phenyl ester compounds were synthesized and their uv-visible absorption spectra were measured in ethanol. Their protective effects against photofading of Crystal Violet, Rose Bengal and Orange I were also examined in cellulose acetate film. The application of simple uv absorbing compounds is not necessarily useful for improving the light fastness of dyes. Phenyl ester uv absorbers bearing a singlet oxygen quencher, however, almost perfectly suppress photofading rate of these dyes. The introduction of a singlet oxygen quenching group into the uv absorber plays a very important role in improving the light fastness of dyes. These new stabilizers have further uv-blocking property and are safe for the environment and human health.
