Claim 0:
1. A polymerizable composition for a dental material, the polymerizable composition comprising:
one selected from the group consisting of allyl compound (A) and an oligomer of allyl compound (A),
(meth)acrylate compound (B), and
optionally a polymerization initiator,
wherein the allyl compound (A) includes compound (A1) represented by general formula (A1) below or compound (A2) represented by general formula (A2) below:, wherein m is an integer of 2 to 8, each group R1 is a hydrogen atom or a methyl group, groups R1 are the same or different, n is an integer of 0 or 1, X is an m-valent C2-100 hydrocarbon group optionally having a substituent and optionally containing a heteroatom,, wherein l is an integer of 1 to 8, each group R10 is a hydrogen atom or a methyl group, groups R10 are the same or different;, if l is 2 to 8, then Y is an l-valent C2-100 hydrocarbon group optionally having a substituent and optionally containing a heteroatom, and, if l is 1, then Y is a group represented by general formula (Y1) below:, wherein R11 is a hydrogen atom or a methyl group, h is an integer of 0 or 1, and the dashed line part represents a bonding position to the group in the parentheses in formula (A2),
wherein the polymerization initiator comprises at least one selected from a room-temperature polymerization initiator, a thermal polymerization initiator and a photopolymerization initiator,
the room-temperature polymerization initiator is at least one selected from an organic peroxide/amine systems, a cumene hydroperoxide/thiourea system, an ascorbic acid/Cu2+ salt system, an organic peroxide/amine/sulfinic acid, tributylborane, and organic sulfinic acid,
the thermal polymerization initiator is at least one selected from a peroxide and an azo compound.
