Abstract: A two-agent type composition consisting of first agent and second agent, wherein: first agent contains an elastomer, a first and second acrylic component, a second acrylic component, and a polymerization initiator; second agent contains condensate of amine and aldehyde, third acrylic component, and reducing agent; the first acrylic component is (meth)acrylate or (meth)acrylic acid, containing two or more hydroxyl groups bonded to a carbon atom in one molecule, or containing one or more functional groups of one or more kind of functional groups selected from group consisting of an amide group, a cyclic amide group, a sulfoxide group, a ketone group, an aldehyde group, a sulfo group, a sulfino group, a phosphonic group, a sulfobetaine group, a carbobetaine group, and a phosphobetaine group in one molecule; second acrylic component is a (meth)acrylate or (meth)acrylic acid other than first acrylic component; and the third acrylic component is (meth)acrylate or (meth)acrylic acid.

Abstract: A composition having excellent curability and adhesive bonding ability is provided. A composition, comprising the following components (1) to (5): (1) a polymerizable vinyl monomer containing 10 to 70 parts by mass of (1-1), 10 to 60 parts by mass of (1-2), and 10 to 60 parts by mass of (1-3) based on 100 parts by mass of (1) the polymerizable vinyl monomer, in which (1-1) is a (meth)acrylic monomer represented by the formula (A) Formula (A) Z—O—R1 (wherein, Z represents a (meth)acryloyl group, and R1 represents an alkyl group.), (1-2) is a (meth)acrylic monomer represented by the formula (B) (wherein, Z and Z′ represent a (meth)acryloyl group, and R2 and R2′ represent an alkylene group; R2 and R2′ may be the same as or different from one another; R3 and R3′ represent a hydrogen atom, or an alkyl group having 1 to 4 carbon atoms; R3 and R3′ may be the same as or different from one another; m and n represent an average number of moles of alkylene oxide added (proportion of alkylene oxide added)), (1-3) is a (meth)acrylic monomer that is a (meth)acrylic acid ester of a polyhydric alcohol; (2) a thermal radical polymerization initiator; (3) a photo-radical polymerization initiator; (4) an aromatic amine and/or pyridine derivative; and (5) an organic metal salt,
