    摘要： The present invention involves the design of a radiation curable organic pre polymer resin material based on urethane acrylic linkage synthesized from the natural renewable resource cardanol or a derivative thereof, for coating application. These new molecules have a faster and better curing rate compared to the starting renewable resource—cardanol. This is brought about by the hydrogen bonding of the urethane linkage which leads to a pre organization of the molecules in such a way as to bring the cross linkable double bonds closer to each other. The present invention also involves a UV curable formulation of the above mentioned resins along with 2-10 parts by weight of a photopolymerization initiator. The resin, either in a formulation or alone turns into a cross linked film upon photopolymerization in presence of photoinitiator under a UV curable radiation source like a mercury vapor pressure lamp.

    摘要翻译： 本发明涉及一种基于由天然可再生资源腰果酚或其衍生物合成的氨基甲酸酯丙烯酸连接物用于涂布应用的可辐射固化的有机预聚物树脂材料的设计。 与起始的可再生资源 - 腰果醇相比，这些新分子具有更快和更好的固化速率。 这是通过氨基甲酸酯键的氢键引起的，这导致分子的预组织，使得可交联的双键更接近彼此。 本发明还涉及上述树脂的UV固化制剂以及2-10重量份的光聚合引发剂。 在紫外光固化辐射源如水银蒸汽压力灯下，在光引发剂存在下光聚合时，制剂中的树脂或单独的树脂变成交联膜。
