ACID-PRODUCING TYPE VISIBLE LIGHT POLYMERIZATION INITIATOR AND PHOTOPOLYMERIZATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an acid-producing type visible light polymerization initiator which is irradiated with visible light to produce an acid without using ultraviolet light, and to provide a photopolymerization method for polymerizing a cation-polymerizable functional group-having monomer or prepolymer in the presence of the acid-producing type visible light polymerization initiator.;SOLUTION: This acid-producing type visible light polymerization initiator contains a p-benzoquinonylsulfanyl derivative and a sulfonium salt- or iodonium salt-based photo acid-producing agent as essential components. This photopolymerization method is characterized by irradiating a cation-polymerizable functional group-containing compound with visible light in the coexistence of the acid-producing type visible light polymerization initiator.;COPYRIGHT: (C)2004,JPO
