Abstract
Provided is a polymerization initiator, which has an excellent curing rate and is an alternative to a polymerization initiator system using a benzoyl peroxide-aromatic amine compound, a curable composition containing the polymerization initiator, a dental material and dental filler material containing the composition, and a kit for preparing the curable composition. The polymerization initiator contains one or more compounds (A) selected from the group consisting of a pyrazolidinedione compound and/or pyrazolidine(di)thione compound (A1), a salt (A2) of the compound (A1), and a malonate compound (A3).
Claims5
A kit for preparing a curable composition, comprising
- a first pack containing a compound (A) selected from the group consisting of a pyrazolidinedione compound and/or pyrazolidine (di) thione compound (A1), and a salt (A2) of the compound (A1), and
- a second pack containing a transition metal compound (B),
- wherein at least one of the first pack and the second pack contains a polymerizable monomer (C) and a peroxide (D).
