Description
Summary:A study was conducted of the excited states of the combination eosine/amine/iodonium salt through time‐resolved laser spectroscopy, of the photolysis products formed under light exposure, and of the rates of polymerization. It allows the process to be precised and discussed. It is apparent that the iodonium salt has no effect on the initiation step of the polymerization reaction but sharply decreases the termination reactions. The formation of a complex between eosine and the iodonium salt is suggested; this complex is destroyed in the presence of amine.
