Cationically polymerizable adhesive composition

摘要

An adhesive composition that includes a mixture of a cationically polymerizable component, an acidic component, and an initiator is provided. Preferably, the initiator comprises an iodonium salt, a visible light sensitizer, and an electron donor compound, wherein the initiator has a photoinduced potential greater than or equal to that of N,N-dimethylaniline in a standard solution of 2.9x10<-5> moles/g diphenyl iodonium hexafluoroantimonate and 1.5x10<-5> moles/g camphorquinone in 2-butanone. This adhesive composition is cationically polymerizable and is able to bond to hard tissue and cationic restorative materials upon curing.
