  The present invention relates to photocurable compositions, comprising a limonene-based (meth)acrylate (A) obtainable by reacting a) 1 equivalent of a compound of formula especially with 1 to 3 equivalents of a compound of formula in the presence of a catalyst and an inhibitor at elevated temperature and its use in a photopolymerization 3D printing process. The limonene-based (meth)acrylate (A) significantly increases stiffness and glass transition temperatures of photo-cured acrylate compositions. While such effects are usually achieved with the use of aromatic or bisphenol A based compounds, the limonene-based (meth)acrylate (A) offers a sustainable alternative at much lower viscosity.

  本发明涉及光固化组合物，该组合物包含柠檬烯基 (甲基) 丙烯酸酯 (A)，可通过反应 a) 1 个当量的式化合物 特别是 与 1 至 3 个当量的式化合物反应 在催化剂和抑制剂存在下，在高温下进行光聚合 3D 打印工艺。柠檬烯基（甲基）丙烯酸酯（A）可显著提高光固化丙烯酸酯组合物的硬度和玻璃化转变温度。通常使用芳香族或双酚 A 类化合物可以达到这种效果，而柠檬烯基（甲基）丙烯酸酯（A）则提供了一种粘度低得多的可持续替代品。

  The present invention relates to prepolymers of formula a process for the production of the prepolymers, photocurable compositions, comprising the prepolymers of formula (I) and their use in a photopolymerization 3D printing process. In contrast to usual urethane (meth)acrylates. The prepolymers of formula (I) can be prepared without using toxic isocyanates and exhibit pending hydroxyl groups along their molecule backbone which allow for the introduction of further side chains or side groups to improve, for example, the interaction with inorganic fillers.

  本发明涉及式如下的预聚物 式 (I) 的预聚物的生产工艺、光固化组合物（包括式 (I) 的预聚物）及其在光聚合 3D 打印工艺中的用途。与通常的聚氨酯（甲基）丙烯酸酯不同。式（I）的预聚物无需使用有毒的异氰酸酯即可制备，其分子骨架上的羟基尚未完全形成，因此可以引入更多的侧链或侧基，以改善与无机填料等的相互作用。
