Methyl oxirane dibenzoylresorcinol UV absorbers |
摘要 |
An epoxylated DBR, dibenzoylresorcinol and various derivatives thereof have been prepared to show usefulness in coatings due to compatibility and solubility. Such coatings can be acrylics, epoxies, or silicone hardcoats which are thermally or photo cured thermoset, or thermoplastic coating materials in a variety of solvent types. The disclosed UV absorber also has the advantage of a higher molecular weight and lower volatility than DBR alone thus providing processing advantages.
