CATIONICALLY POLYMERIZABLE ADHESIVE COMPOSITION CONTAINING AN ACIDIC COMPONENT

An adhesive composition that includes a mixture of a canonically 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 pote...

Beschreibung
Zusammenfassung:	An adhesive composition that includes a mixture of a canonically 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 1.5x 10-5 moles/g camphorquinone in 2-butanone. Thi s adhesive composition is cationically polymerizable and is able to bond to hard tissue and cationic restorative materials upon curing.
