Abstract

The excited state interactions occurring in a three- component system which can be used under visible laser light excitation and based on a derived dye thioxanthene derived dye TXD, an amine and an additive such as diphenyliodonium salt wee investigated through time-resolved absorption spectroscopy, spectrofluorometry and steady state photolysis. The rate constants of the various chemical processes taking place in the initiation step were measured. An overall photoinitiation mechanism is proposed. A sensitivity of 0.3 mJ cm^-2 obtained under laser scanning exposition is also reported.
