[Uses]

2-(2'-Hydroxy-4'-benzoyloxyphenyl)-5-chlorobenzotriazole is characterized by its large molecular weight, low volatility, resistance to extraction, and ease of processing. It boasts high UV protection efficiency, with a UV molar extinction coefficient 2.6 times that of benzophenone-based absorbers and 1.8 times that of traditional benzotriazole (alkylphenol-substituted derivative) absorbers. This material exhibits strong adsorption properties, particularly for microfibers, surpassing the performance of triazine-based absorbers. It also demonstrates excellent performance on polyester fibers.
