## Abstract

An object of the present invention is to provide a cyclohexene oxide compound that gives a cured resin having a low refractive index and excellent transparency, curability, mold release properties, and mechanical properties, and that can be used as a component of an actinic radiation curing composition and/or heat curing composition. The present invention is a cyclohexene oxide compound having a cyclohexyl group or a long-chain alkyl group, represented by Formula (1) below (in Formula (1), A denotes a cyclohexyl group, Formula (2) below, or an optionally branched alkyl group having 8 to 16 carbons) (in Formula (2), R1 denotes a hydrogen atom or an optionally branched alkyl group having 1 to 4 carbons and R2 denotes a hydrogen atom or an optionally branched alkyl group having 1 to 4 carbons).

## Claims

### Claim 1

An actinic radiation curing composition and/or heat curing composition comprising a cyclohexene oxide compound represented by Formula (1) below and a cationic polymerization initiator,
wherein A denotes a cyclohexyl group, Formula (2) below, or a branched alkyl group having 8 to 16 carbons,
wherein R1 denotes a hydrogen atom or an optionally branched alkyl group having 1 to 4 carbons and R2 denotes a hydrogen atom or an optionally branched alkyl group having 1 to 4 carbons.

### Claim 2 (depends on 1)

A cured material formed by irradiating with actinic radiation and/or heating the curing composition according to claim 1.

### Claim 3 (depends on 1)

The actinic radiation curing composition according to claim 1, wherein the cationic polymerization initiator is a actinic radiation-latent cationic polymerization initiator.

### Claim 4 (depends on 1)

The heat curing composition according to claim 1, wherein the cationic polymerization initiator is a thermo-latent cationic polymerization initiator.
