1. A dental polymerizable composition comprising:
a first agent containing a (meth)acrylate, a thiourea derivative, vanadyl acetylacetonate, and a β-diketone; and
a second agent containing a (meth)acrylate and an organic peroxide, wherein
the β-diketone is either acetylacetone, 1-phenyl-1,3-butanedione, or both,
a content of the β-diketone in the first agent is 0.45% by mass or more and 0.9% by mass or less, and
a content of vanadyl acetylacetonate in the first agent is 0.012% by mass or more and 0.024% by mass or less.
