    Abstract: The invention provides a radically polymerizable resin composition capable of suppressing shrinkage while maintaining strength by adding an appropriate amount of an expansive additive to the radically polymerizable resin composition causing curing shrinkage by a decrease in the free volume of a liquid component during curing. The radically polymerizable resin composition comprises a radically polymerizable compound (A), an expansive additive (B), a radical polymerization initiator (C), and an aggregate (D). The aggregate (D) contains cement. The aggregate (D) is 330 to 800 parts by mass with respect to 100 parts by mass of the radically polymerizable compound (A).

    Abstract: A curing accelerator can exhibit good curing acceleration performance and is excellent in storage stability, while maintaining sufficient pot life in a curing reaction of radical-polymerizable resins, and a radical-polymerizable resin composition uses the curing accelerator. The curing accelerator for radical-polymerizable resins includes a metal-containing compound (A), a thiol compound (B) and an aprotic solvent (C) having a dielectric constant of 10 or less, wherein the metal-containing compound (A) is one or more compounds selected from a metal soap (A1) and a β-diketone skeleton-having metal complex (A2), the thiol compound (B) is one or more compounds selected from a mono-functional primary thiol compound (B1), a secondary thiol compound (B2) and a tertiary thiol compound (B3), and the content of the aprotic solvent (C) is 10 to 1,000 parts by mass relative to 100 parts by mass of the total of the metal-containing compound (A) and the thiol compound (B).
