Abstract
Disclosed is a photooxidizable initiator composition comprising a fluorone initiator and a coinitiator which is capable of accepting an electron from the fluorone upon excitation of the fluorone by actinic radiation, wherein the composition produces free radicals which initiate free radical reactions; and photohardenable compositions which comprise a free radical polymerizable compound, a fluorone initiator and a coinitiator capable of accepting an electron from the fluorone upon exposure of the composition to actinic radiation, and producing free radicals which initiate free radical polymerization.
