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

1 . A curable composition comprising:
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 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).

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

(In formula (2), L b represents a divalent aromatic hydrocarbon group or —COO—;
L c 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 L b is —COO—, L c 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: L c 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 (1):

(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 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).

8 . The polymerizable compound according to claim 7 which is represented by formula (2):

(In formula (2), L b represents a divalent aromatic hydrocarbon group or —COO—;
L c 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 L b is —COO—, L c 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).

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

10 . 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.

11 . 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.

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

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

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

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