This compound behaves as a strong acid (AH) with an associated basic form (A(-)) that does not inhibit the propagation of the cationic polymerization. Remarkably, A(-) is characterized by a strong visible light absorption and can also photosensitize iodonium salt decomposition. A new iodonium salt based on A(-)as a counter-anion is proposed. This latter compound exhibits unusual properties: (i) excellent absorption in the 300-700 nm wavelength range and (ii) a free radical initiating ability for lambda > 300 nm. The chemical mechanisms are investigated by ESR, fluorescence and steady state photolysis experiments. Show less
