Abstract

A composition is provided which includes a polymerizable compound (A) which includes a (meth)acryloyl group and an isocyanate group in a molecule thereof; and a reaction accelerator (B) which is a compound including a (meth)acryloyl group and a halogenated carbamoyl group in a molecule.

First claim

1 . A composition comprising:
a polymerizable compound (A) which includes a (meth)acryloyl group and an isocyanate group in a molecule thereof; and a reaction accelerator (B) which is a compound including a (meth)acryloyl group and a halogenated carbamoyl group in a molecule thereof.

2 . The composition according to claim 1 , wherein the amount of the reaction accelerator (B) is in a range of 5 ppm by mass to 20000 ppm by mass with respect to the amount of the polymerizable compound (A).

3 . The composition according to claim 1 , wherein the amount of the reaction accelerator (B) is in a range of 5 ppm by mass to 8000 ppm by mass with respect to the amount of the polymerizable compound (A).

4 . The compound according to claim 1 , wherein the polymerizable compound (A) is a compound represented by the following general formula (1) or (1′)

wherein, in the formula, R 1 and R 2 each independently represent a hydrogen atom or a methyl group, R 3 represents an alkylene group which may include a substituent and has 1 to 10 carbon atoms or a group formed by substituting a single bond between carbon atoms of the alkylene group with a bond selected from a group consisting of an ether bond, an ester bond, and a phenylene bond, and two R 1 's in the formula (1′) may be the same as or different from each other and two R 3 's may be the same as or different from each other.

5 . The composition according to claim 1 , wherein the reaction accelerator (B) is a compound represented by the following general formula (2) or (2′)

wherein, in the formula, R 1 and R 2 each independently represent a hydrogen atom or a methyl group, R 3 represents an alkylene group which may include a substituent and has 1 to 10 carbon atoms or a group formed by substituting a single bond between carbon atoms of the alkylene group with a bond selected from a group consisting of an ether bond, an ester bond, and a phenylene bond, X represents a fluorine atom, a chlorine atom, a bromine atom, or an iodine atom, and two R 1 's in the formula (2′) may be the same as or different from each other and two R 3 's may be the same as or different from each other.

6 . The composition according to claim 5 ,
wherein the polymerizable compound (A) contains a compound represented by the formula (1) or (1′), and the reaction accelerator (B) contains a compound which is represented by the formula (2) or (2′) and in which R 1 , R 2 , and R 3 in the formula (2) or (2′) respectively have the same definitions as those for R 1 , R 2 , and R 3 of the polymerizable compound (A).

7 . The composition according to claim 1 , further comprising a compound which includes an active hydrogen-containing group.

8 . The composition according to claim 7 , wherein the active hydrogen-containing group is at least one selected from a group consisting of a hydroxyl group, a mercapto group, a carboxyl group, and an amino group.

9 . A curable composition which comprises a polymerizable compound which is formed by reacting the polymerizable compound (A) with the compound including the active hydrogen-containing group in the composition according to claim 8 , wherein the polymerizable compound includes a (meth)acryloyl group and at least one selected from a group consisting of a urethane bond, a thiourethane bond, an amide bond, and a urea bond in a molecule thereof.

10 . A method of producing a curable composition comprising:
reacting the polymerizable compound (A) with the compound including the active hydrogen-containing group in the composition according to claim 8 to obtain a curable composition which includes a polymerizable compound which has a (meth)acryloyl group and at least one selected from a group consisting of a urethane bond, a thiourethane bond, an amide bond, and a urea bond in a molecule thereof.

11 . A cured product which is formed by curing the curable composition according to claim 9 .

12 . The composition according to claim 2 , wherein the amount of the reaction accelerator (B) is in a range of 5 ppm by mass to 8000 ppm by mass with respect to the amount of the polymerizable compound (A).
