Visible light polymerization initiator and visible light polymerizable composition

摘要

PROBLEM TO BE SOLVED: To obtain a visible-rays-induced polymerization initiator having improved sensitivity to the visible rays and safety and giving a polymerizable composition excellent in adhesion to substrates by mixing a coumarin dye with a specified photic acid generator and an aryl borate compound. ;SOLUTION: This visible-rays-induced polymerization initiator is obtained by mixing 0.00001-50wt.% coumarin dye of formula I [wherein R₁ to R₃ are each H, a halogen, an alkyl, an alkoxyl, amino, an alkylamino or an alkenylamino; A is H, cyano or an alkyl; and B is H, an aryl, a 5-9C heterocyclic ring or a group of formula II (wherein Z is a 1-4C alkyl or alkenyl or 3'-coumarino)] with 0.005-95wt.% photic acid generator being at least either a halomethyl-substituted S-triazine derivative or a diphenyliodonium chloride and 0.01-95wt.% aryl borate compound. The visible-rays-induced-polymerizable composition is obtained by mixing 0.01-10 pts.wt., per 100 pts.wt total polymerizable monomer of the composition, this initiator and a polymerizable monomer containing a (meth)acrylate nonomer.;COPYRIGHT: (C)1997,JPO
