ABSTRACT:
A novel initiator for photopolymerization is provided, which can polymerize cationically polymerizable organic material by only irradiating at wavelength of 200-500 nm without specific sensitizer and/or post-curing even when it is used at comparatively small amount, whereby the obtained cured product has good physical properties and electric properties. The initiator for photopolymerization of cationically polymerizable organic material according to the present invention comprises a composite obtainable from a reaction between (a) charge transfer complex consisting of biscyclopentadienyl iron derivative and quinoid and (b) at least one salt selected from a group consisting of tetrafluoroborates, hexafluorophosphates and hexafluoroantimonates.
