In this paper, visible light photoinitiating systems are developed for Free Radical Photopolymerization FRP. The use of borate salts as coinitiators was found to yield high rate of polymerization as well as high final conversion when combined with a dye abosrbing in the UV-visible range. The mechanism of reaction was investigated by laser flash photolysis. The mechanism is discussed in terms of photoinduced electron transfer and fast dissociation of borate radical.
