More Information
Summary:PURPOSE:To provide the titled composition obtained by separately packaging a polymerizable ethylenic unsaturated compound, a photo-polymerization initiator and a reducing agent as one package and a filler and an organic peroxide as the other package, usable by mixing the separately packaged components with each other in use and uniformly curable to deep part by the irradiation of visible light for a short time. CONSTITUTION:(A) A composition composed mainly of (A1) a polymerizable ethylenic unsaturated initiator such as alpha-diketone compound (e.g. camphor- quinone), a ketal compound (e.g. benzylmethyl ketal), an anthraquinone compound or a thioxanthone compound and (A3) a reducing agent which can reduce a photo-sensitizer in excited state but cannot reduce the sensitizer in unexcited state (e.g. triethanolamine) and (B) a composition composed mainly of a filler and an organic peroxide (e.g. benzoyl peroxide) are separately packaged and both packaged components are mixed with each other in use.
