阅读说明：本技术 浅色松香酯组合物及其制备方法 (Light-colored rosin ester composition and preparation method thereof ) 是由 M·C·沙普曼 于 2018-06-30 设计创作，主要内容包括：公开了浅色或低色松香或松香酯组合物。通过使用助催化剂,得到了颜色显著改善的低色松香或松香酯。在一个实施方案中,助催化剂的三线态形成量子产率(Φ<Sub>T</Sub>)大于0.5,且三线态寿命(τ<Sub>T</Sub>)大于0.5微秒。在另一个实施方案中,助催化剂选自吖啶酮、蒽酮、9-芴酮、噻吨酮、氧杂蒽酮、衍生物或其组合。(Light or low color rosin or rosin ester compositions are disclosed. By using the cocatalyst, a low-color rosin or rosin ester with a significantly improved color is obtained. In one embodiment, the triplet-forming quantum yield (Φ) of the promoter T ) Greater than 0.5 and triplet lifetime (τ) T ) Greater than 0.5 microseconds. In another embodiment, the co-catalyst is selected from the group consisting of acridone, anthrone, 9-fluorenone, thioxanthone, xanthone, derivatives, or combinations thereof.)
