Document Type and Number:
Japanese Patent JP2020147603
Kind Code:
A
Abstract:
To provide a dental visible light polymerizable composition having sufficient mechanical strength and low shrinkage stress during curing.SOLUTION: There is provided a dental visible light polymerizable composition comprising (a) a (meth) acrylic group-containing polymerizable monomer containing a bifunctional aromatic (meth) acrylic group-containing polymerizable monomer and/or a bifunctional aliphatic (meth) acrylic group-containing polymerizable monomer; (b) a polymerization initiator selected from any of a polymerization initiator consisting of a combination of (b1) α-diketone compound and (b2) amine compound or (b3) a single molecule cleavage type photopolymerization initiator; and (c) a compound having a quinone structure other than the α-diketone compound such as 1,4-naphthoquinone compound, which functions as a chain transfer agent and a radical generator. The total compounding amount of the above (c), the above (b1) or (b3) with respect to 100 parts by mass of the above (a) is 0.2 to 2.0 parts by mass.SELECTED DRAWING: None
