  Provided is a Michael addition product prepared from a multifunctional acryl monomer having multiple hydroxyl groups allowing introduction of acryl functional groups, as a Michael acceptor, and a Michael donor. The Michael addition product is a novel multifunctional compound having an oligomer and a photoinitiator moiety in the molecule. Since it can be cured under a standard UV curing condition without having to add a photoinitiator, it is reduced to air pollution or health problem. Therefore the superior physical properties were obtained by cured coatings without surface tackiness. In addition, its hydroxyl groups allow, through isocyanate bonding or introduction of acryl groups, 3-dimensional crosslinking and molecular and compositional design for improving expandability, friction, and reactivity and hydrophilicity for self-adhesion, hardness of cured film, or the like. Consequently, a very useful, multifunctional or water-dispersible coating composition may be prepared.

  提供的是从具有多个羟基的多功能丙烯酸单体制备的Michael加成产物，允许引入丙烯酸功能团作为Michael受体和Michael给体。该Michael加成产物是一种新颖的多功能化合物，在分子中具有寡聚体和光引发剂基团。由于它可以在标准紫外光固化条件下固化，无需添加光引发剂，因此减少了空气污染或健康问题。因此，通过固化涂层获得了优越的物理性能，而无需表面粘性。此外，其羟基通过异氰酸酯键合或引入丙烯基，允许进行三维交联和分子和组成设计，以改善可扩展性、摩擦、反应性和亲水性，用于自粘附、固化膜的硬度等。因此，可以制备非常有用的多功能或水分散性涂料组合物。
