Abstract: Uv-curing technology was widely used in many fields including paints, printing inks and adhesives for its great benefits in low energy consuming and environment protection. Photoinitiator played the most important role in Uv-curing system, its exploitation and development had a significant impact on the progress of UV curing products. The classification. character and synthetic method of traditional photoinitiator were summarized in this article, and the developing direction of photoinitiator was pointed out. The advantages, character and synthetic method of new photoinitiator were also introduced.

Key words: Uv-curing, aromatic diazonium salt, aromatic ketone, acvl-phosphine oxide, aromaticonium salt, two-photon
