Abstract

Provided is a curable-type composition, including a methylene malonate compound, a Lewis acidic compound, and a photo base generator.

First claim

What is claimed is:

1. A curable-type composition, comprising:
a methylene malonate compound;
a Lewis acidic compound; and
a photo base generator.

2. The curable-type composition according to claim 1 , wherein the methylene malonate compound is a compound represented by the following Formula (1) or Formula (2):

wherein, in Formula (1) and Formula (2), each of X 1 to X 4 independently represents O, NR, or C(R) 2, wherein each R independently represents a hydrogen atom, an alkyl group, or an aryl group, R 1 and R 2 each independently represent an alkyl group or an aryl group, and R 3 represents an alkylene group, an arylene group, or a group that is a combination of two or more thereof.

3. The curable-type composition according to claim 1 , wherein the Lewis acidic compound comprises a Lewis acidic compound having a metal cation.

4. The curable-type composition according to claim 1 , wherein the Lewis acidic compound comprises a Lewis acidic compound having at least one metal cation selected from the group consisting of Fe 2+ , Cu 2+ , Zn 2+ , Ag + , Yb 3+ , and Ti 4+ .

5. The curable-type composition according to claim 1 , wherein the Lewis acidic compound comprises a Lewis acidic compound having at least one counter anion selected from the group consisting of a trifluoromethanesulfonic anion, a tert-butoxide anion, an acetylacetonate anion, a chloride ion, and a bromide ion.

6. The curable-type composition according to claim 1 , wherein a content of the Lewis acidic compound is from 0.001 parts by mass to 1.0 part by mass with respect to a content of the methylene malonate compound of 100 parts by mass.

7. The curable-type composition according to claim 1 , wherein each of X 1 to X 4 independently represents O or NR.

8. The curable-type composition according to claim 1 , wherein each of X 1 to X 4 represents O.

9. The curable-type composition according to claim 1 , wherein R 1 and R 2 each independently represent an alkyl group.

10. The curable-type composition according to claim 1 , wherein R 3 represents an alkylene group.

11. The curable-type composition according to claim 1 , the composition comprising the compound represented by Formula (1).

12. The curable-type composition according to claim 1 , wherein the photo base generator comprises a compound that generates an amine compound in response to light.

13. A method of producing an adhered product, the method comprising:
applying the curable-type composition according to claim 1 to a surface of a first adherend;
affixing the surface of the first adherend, to which the curable-type composition has been applied, to a second adherend; and
irradiating the curable-type composition between the first adherend and the second adherend with light from a side of an adherend having light transparency, wherein at least one of the first adherend or the second adherend is the adherend having light transparency.

14. A two-component curable-type composition set, comprising:
a composition A that comprises a methylene malonate compound and a photo base generator; and
a composition B that comprises a Lewis acidic compound.

15. The two-component curable-type composition set according to claim 14 , wherein the methylene malonate compound is a compound represented by the following Formula (1) or Formula (2):

wherein, in Formula (1) and Formula (2), each of X 1 to X 4 independently represents O, NR, or C(R) 2 , wherein each R independently represents a hydrogen atom, an alkyl group, or an aryl group, R 1 and R 2 each independently represent an alkyl group or an aryl group, and R 3 represents an alkylene group, an arylene group, or a group that is a combination of two or more thereof.

16. A method of producing an adhered product, the method comprising:
applying a composition B that comprises a Lewis acidic compound to a surface of a first adherend;
applying a composition A that comprises a methylene malonate compound and a photo base generator, to the surface of the first adherend or a surface of a second adherend;
affixing the surface of the first adherend to which the composition B has been applied, to the surface of the second adherend to which the composition A has been applied, or affixing the surface of the first adherend to which the composition A and the composition B have been applied, to the surface of the second adherend; and
irradiating the curable-type composition between the first adherend and the second adherend with light from a side of an adherend having light transparency, wherein at least one of the first adherend or the second adherend is the adherend having light transparency.

17. The method of producing an adhered product according to claim 16 , wherein the methylene malonate compound is a compound represented by the following Formula (1) or Formula (2):

wherein, in Formula (1) and Formula (2), each of X 1 to X 4 independently represents O, NR, or C(R) 2, wherein each R independently represents a hydrogen atom, an alkyl group, or an aryl group, R 1 and R 2 each independently represent an alkyl group or an aryl group, and R 3 represents an alkylene group, an arylene group, or a group that is a combination of two or more thereof.
