Abstract:
    Photocurable, addition polymerizable compositions contain an epoxy resin and a photoinitiator system containing (a) an epoxy resin and (b) a photoinitiator system comprising: (i) an iodonium salt; (ii) a visible light sensitizer; and (iii) an electron donor compound, wherein the photoinitiator system has a photoinduced potential of at least about 0mV relative to a standard solution of 2.9X10-5 moles/g diphenyl iodonium hexafluoroantimonate and 1.5X10
Time: 10
