2-Hydroxybenzophenone derivatives substituted in the 4′-position by a thioether moiety exhibit enhanced absorption in the UV at longer wavelength. Compositions comprising organic material subject to actinic degradation are beneficially stabilized with such derivatives.
2-羟基苯并苯酮的4'-位置上带有硫醚基团衍生物在较长的紫外波长下具有增强的吸收作用。包含易受辐射降解的有机物质的组合物用此类衍生物进行稳定化处理是有益的。
