  The present invention provides a photocurable composition prepared using mercapto benzophenone compounds as key raw materials. The present invention aims to solve the problems existing in the prior photo-curing technology that low-molecular photoinitiators are easy to remain and migrate, while macromolecular photoinitiators has low initiation efficiency due to a low content of effective components and also has the problem of certain migration. The photocurable composition in the present invention can be easily prepared and has high addition efficiency with ethylenically unsaturated compounds, and the photocurable composition obtained by addition has no residual mercapto and has features of high initiation activity and zero migration rates when it is used in photocurable coatings, binder and ink formula.

  本发明提供了一种以巯基二苯甲酮化合物为主要原料制备的光固化组合物。本发明旨在解决现有光固化技术中存在的低分子光引发剂容易残留和迁移，而大分子光引发剂由于有效成分含量低，引发效率低，同时还存在一定的迁移问题。本发明中的光固化组合物制备简便，与乙烯基不饱和化合物的加成效率高，加成得到的光固化组合物无巯基残留，用于光固化涂料、粘结剂和油墨配方时，具有高引发活性和零迁移率的特点。
