Primer composition and curable composition

摘要

A curable composition comprising a polymerizable monomer having an acidic group in its molecule and an initiator. The composition has a viscosity in the range of from 100 to 30,000 cP at 37.5 DEG C. and may have additionally contain other polymerizable monomer and/or a filler. The composition is applied to a tooth surface directly or after applying a primer composition. There is also provided the primer composition which comprises a polymerizable monomer having an acidic group and a solvent.
