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

The invention claimed is:

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,
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).

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 8000 ppm by mass with respect to the amount of the polymerizable compound (A).

3. The composition 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 the 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.

4. 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 the 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.

5. The composition according to claim 4 ,
wherein the polymerizable compound (A) contains a compound represented by the following 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 the 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, and
in the case where the polymerizable compound (A) contains a compound represented by the formula (1), the reaction accelerator (B) contains a compound which is represented by the formula (2) and in which R1, R2, and R3 in the formula (2) are respectively the same as R1, R2, and R3 included in the polymerizable compound (A),
in the case where the polymerizable compound (A) contains a compound represented by the formula (1′), the reaction accelerator (B) contains a compound which is represented by the formula (2′) and in which R1, R2, and R3 in the formula (2′) are respectively the same as R1, R2, and R3 included in the polymerizable compound.

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

7. The composition according to claim 6 , wherein the active hydrogen-containing group is at least one selected from the group consisting of a hydroxyl group, a mercapto group, a carboxyl group, and an amino group.
