Abstract

Provided are a curable composition including a compound represented by General Formula (1) or (2), a cured product, an optical material, and a diffractive optical element, each of which uses the curable composition, and a compound represented by General Formula (1) or (2).

In the formulae, Q 1 represents a group represented by Formula (q1a) or (q1b), Q 2 represents a group represented by Formula (q2), and Q 3 represents a group represented by Formula (q3).

In the formulae, R 1 represents a (meth)acryloyl group, a vinyl group, or an allyl group. * represents a bonding site.

First claim

What is claimed is:

1 . A curable composition comprising:
a compound represented by General Formula (1) or (2),

in the formulae, Q 1 represents a group represented by Formula (q1a) or (q1b), Q 2 represents a group represented by Formula (q2), and Q 3 represents a group represented by Formula (q3),

in the formulae, R 1 represents a (meth)acryloyl group, a vinyl group, or an allyl group, and * represents a bonding site.

2 . The curable composition according to claim 1 ,
wherein the compound represented by General Formula (1) or (2) includes at least one of a compound in which substitution positions of the substituents (Q 1 and Q 3 ) in General Formula (1) are (1,5) positions, (1,6) positions, (2,7) positions, (5,1) positions, (6,1) positions, or (7,2) positions of a naphthalene ring, or a compound in which substitution positions of the substituents (Q 2 and Q 3 ) in General Formula (2) are (1,5) positions, (1,6) positions, (2,7) positions, (5,1) positions, (6,1) positions, or (7,2) positions of a naphthalene ring.

3 . The curable composition according to claim 2 ,
wherein the compound represented by General Formula (1) or (2) includes at least one compound represented by any of General Formulae (3) to (6),

in the formulae, R 1 has the same definition as R 1 described above, and R 2 represents a hydrogen atom or a methylsulfanyl group.

4 . The curable composition according to claim 1 , further comprising:
a compound represented by General Formula (7),

in the formula, Q 4 and Q 5 represent a group represented by any of Formula (q1a), (q1b), (q2), or (q3), provided that one of Q 4 and Q 5 is a group represented by any of Formula (q1a), (q1b), or (q2) and the other is not a group represented by Formula (q3),

in the formulae, R 1 represents a (meth)acryloyl group, a vinyl group, or an allyl group, and * represents a bonding site.

5 . The curable composition according to claim 1 ,
wherein the curable composition is for imprinting.

6 . A cured product obtained from the curable composition according to claim 1 .

7 . An optical material comprising:
the cured product according to claim 6 .

8 . A diffractive optical element which is formed of the cured product according to claim 6 , comprising:
a surface having a diffraction grating shape.

9 . A compound represented by General Formula (1) or (2),

in the formulae, Q 1 represents a group represented by Formula (q1a) or (q1b), Q 2 represents a group represented by Formula (q2), and Q 3 represents a group represented by Formula (q3),

in the formulae, R 1 represents a (meth)acryloyl group, a vinyl group, or an allyl group, and * represents a bonding site.
