Abstract

Official abstract text for this publication.

According to the present invention, a curable composition can be provided, said composition being characterized by comprising: (A) an episulfide compound; and (B) a photobase generator comprising an organoboron compound represented by general formula (1) below: (In general formula (1), R 1 , R 2 , R 3 , R 4 and R 5 may be the same as or different from one another and independently represent an alkyl group having 1 to 8 carbon atoms; and Ar 1 , Ar 2 and Ar 3 may be the same as or different from one another and independently represent a group selected from the group consisting of a phenyl group, a naphthyl group, an anthracenyl group and a phenanthryl group, each of which may have a substituent selected from the group consisting of an alkyl group, an aryl group, an alkenyl group, a cycloalkyl group and a heterocyclic group.)

First claim

Opening claim text (preview).

The invention claimed is: 1. A curable composition comprising: (A) an episulfide compound; and (B) a photobase generator comprising an organoboron compound represented by general formula (1) below: wherein in general formula (1): R 1 , R 2 , R 3 , R 4 and R 5 may be the same as or different from one another and independently represent an alkyl group having 1 to 8 carbon atoms; and Ar 1 , Ar 2 and Ar 3 may be the same as or different from one another and independently represent a group selected from the group consisting of a phenyl group, a naphthyl group, an anthracenyl group and a phenanthryl group, each of which may have a substituent selected from the group consisting of an alkyl group, an aryl group, an alkenyl group, a cycloalkyl group and a heterocyclic group, wherein (A) the episulfide compound is a compound represented by general formula (2) below: wherein in general formula (2), m represents an integer from 0 to 4 and n represents an integer from 0 to 2, and wherein the ratio of (A) the episulfide compound in the curable composition is 30 to 99.9% by mass. 2. The curable composition according to claim 1 , wherein the compound represented by general formula (2) is bis(β-epithiopropyl)sulfide. 3. The curable composition according to claim 1 , further comprising (C) a sensitizer. 4. The curable composition according to claim 1 , further comprising (D) a thiol compound. 5. A method for producing a cured product, which comprises curing the curable composition according to claim 1 by ultraviolet or visible-light irradiation. 6. A cured product obtained by the production method according to claim 5 . 7. An optical material comprising the cured product according to claim 6 . 8. An optical adhesive comprising the curable composition according to claim 1 . 9. An optical material, wherein a microstructure is formed on the surface of a substrate, and wherein the curable composition according to claim 1 is used for forming the microstructure.
