Low migration and high performance thioxanthone based photoinitiators

Recent Advances in Photoredox Catalysts

“…Thioxanthone is a historical photoinitiator that was studied at the early stage of photopolymerization [23][24][25][26][27][28]. In as early as 1967, Davidson and Lambeth proposed a generation of initiating radicals via the photoreduction of thioxanthone with aliphatic tertiary amines [29].…”
