光引发剂的新发展为辐射固化技术的进一步推广奠定了基础。介绍了三种不同的方法：双酰基氧化膦光引发剂与合适的稳定剂包的优化组合允许在户外使用中具有优异性能的透明涂料的UV固化。新肟酯衍生物的设计允许引入用于滤色器抗蚀剂应用的新定制光引发剂，其显著改善滤色器的颜色质量。一种新型的光引发剂能够释放出强胺碱，为将辐射固化扩展到通过碱催化过程交联的树脂类型开辟了新的机会。
New developments of photoinitiators are the base for the further extension of the radiation curing technology. Three different approaches are presented: The optimized combination of a bisacylphosphine oxide photoinitiator with a suitable stabilizer package allows the UV curing of clear coatings with an excellent performance in outdoor use. The design of new oxime ester derivatives allowed the introduction of a new tailor-made photoinitiator for color filter resists applications that considerably improves the color quality of the color filter. A novel photoinitiator class capable of releasing strong amine bases opens new opportunities for expanding radiation curing into resins types that crosslink by base-catalyzed processes.
