Thioether substituted hydroxybenzophenones and stabilized compositions |
| 摘要 |
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.
