Abstract

A curable composition capable of manufacturing a cured product having a high refractive index is provided. The curable composition contains a polymerizable compound represented by formula (1) and inorganic particles. In formula (1), L a represents a divalent linking group, and the divalent linking group includes at least one of a divalent aromatic group, a divalent polycyclic aliphatic group and an alkylene group having an aromatic group, Ar represents an aromatic group, and R represents an aromatic group optionally having one or more substituents or a polycyclic aliphatic group optionally having one or more substituents.

First claim

The invention claimed is:

1. A curable composition comprising:
a polymerizable compound represented by formula (1):

where La represents a divalent linking group, and the divalent linking group includes at least one of a divalent aromatic group, a divalent polycyclic aliphatic group and an alkylene group having at least an aromatic group,
Ar represents an aromatic group, and
R represents an aromatic group optionally having one or more substituents or a polycyclic aliphatic group optionally having one or more substituents; and

inorganic particles.

2. The curable compound according to claim 1 , wherein the polymerizable compound represented by formula (1) is a polymerizable compound represented by formula (2):

where Lb represents a divalent aromatic hydrocarbon group or COO—,
Lc represents a single bond, an alkylene group having at least a hydroxy group, an alkylene group having at least an aromatic group, or a divalent polycyclic aliphatic group, and when Lb is —COO—, Lc represents an alkylene group having at least an aromatic group or a divalent polycyclic aliphatic group, and
definitions of Ar and R in formula (2) are identical to definitions of Ar and R in formula (1), respectively.

3. The curable composition according to claim 2 , wherein the polymerizable compound represented by formula (2) satisfies at least one of following requirements 1 and 2:
requirement 1: Lc represents an alkylene group having a hydroxy group;
requirement 2: R represents a polycyclic aliphatic group having a hydroxy group.

4. The curable composition according to claim 1 , wherein the inorganic particles comprise at least one type selected from the group consisting of metal oxide particles and metal sulfide particles.

5. A cured product obtained by curing the curable composition according to claim 1 .

6. An optical member obtained by curing the curable composition according to claim 1 .

7. A polymerizable compound represented by formula (2):

where Lb represents a divalent aromatic hydrocarbon group or COO—,
Lc represents a single bond, an alkylene group having at least a hydroxy group, an alkylene group having at least an aromatic group, or a divalent polycyclic aliphatic group, and when Lb is —COO—, Lc represents an alkylene group having at least an aromatic group or a divalent polycyclic aliphatic group,
Ar represents an aromatic group, and
R represents an aromatic group optionally having one or more substituents or a polycyclic aliphatic group optionally having one or more substituents.

8. The polymerizable compound according to claim 7 , satisfying at least one of following requirements 1 and 2:
requirement 1: Lc represents an alkylene group having a hydroxy group;
requirement 2: R represents a polycyclic aliphatic group having a hydroxy group.

9. The curable composition according to claim 2 , wherein the inorganic particles comprise at least one type selected from the group consisting of metal oxide particles and metal sulfide particles.

10. The curable composition according to claim 3 , wherein the inorganic particles comprise at least one type selected from the group consisting of metal oxide particles and metal sulfide particles.

11. A cured product obtained by curing the curable composition according to claim 2 .

12. A cured product obtained by curing the curable composition according to claim 3 .

13. A cured product obtained by curing the curable composition according to claim 4 .

14. A cured product obtained by curing the curable composition according to claim 9 .

15. A cured product obtained by curing the curable composition according to claim 10 .

16. An optical member obtained by curing the curable composition according to claim 2 .

17. An optical member obtained by curing the curable composition according to claim 3 .

18. An optical member obtained by curing the curable composition according to claim 4 .

19. An optical member obtained by curing the curable composition according to claim 9 .
