Abstract

A single-component dental photopolymerizable composition is provided that includes a (meth)acrylate compound, a vanadium compound, an α-diketone compound, and a tertiary aromatic amine compound.

Claims

1. A single-component dental photopolymerizable composition comprising:

a (meth)acrylate compound, a vanadium compound, an α

-diketone compound, and a tertiary aromatic amine compound.

2. The single-component dental photopolymerizable composition according to claim 1, wherein a content of the vanadium compound in the single-component dental photopolymerizable composition is greater than or equal to 0.001 mass % and less than or equal to 1 mass %.

3. The single-component dental photopolymerizable composition according to claim 1, further comprising a filler.

4. The single-component dental photopolymerizable composition according to claim 1, wherein the single-component dental photopolymerizable composition is used as a composite resin for abutment construction.

5. A photopolymerization initiator comprising:

a vanadium compound, an α

-diketone compound, and a tertiary aromatic amine compound.
