Abstract: UV-curable photosensitive coating technology has special requirements to the object being cured，the curing depth and adhesives，especially for that applied in high-speed automated production lines. On the basis of defect analysis of this technology，the present paper reports the preparation of UV-curable epoxy-acrylic photosensitive resin using epoxy resin and acrylic acid as starting materials，triphenylphosphine as catalyst，and p-benzenediol as inhibitor. Then epoxy-acrylate photosensitive coating was compounded by mixing the resin，reactive diluent and photosensitizer. Influences of the mole ratio，the feeding mode and temperature on resin synthesis，as well as the impact of sensitizer on coating behabiour are also discussed.

摘要： 紫外光固化光敏涂料技术对被固化对象、固化深度和胶黏剂都有一定的要求，因此不能很好地适应高速自动化生产线的要求。本研究以三苯基磷为催化剂、双酚A型环氧树脂和丙烯酸为反应原料制得了环氧丙烯酸光敏树脂，再与活性稀释剂、光敏剂配制成环氧丙烯酸酯光敏涂料。对环氧树脂和丙烯酸的摩尔比、温度、投料方式等因素对合成反应的影响进行了深入研究，对光敏剂对涂料性能的影响也进行了分析，并且得出了合理的使用条件，为紫外光固化光敏涂料技术的应用发展提供了一个新思路。
