Abstract

Provided is a photosensitive resin composition that is, after being applied to an adherend surface, rapidly cured by photoirradiation to form a cured product having excellent light-shielding ability and adhesiveness. The present invention relates to a photosensitive resin composition that includes components as follows:
(A) a cationically polymerizable compound at least including a compound containing an alicyclic epoxy group and devoid of ester bonds; (B) a photo-cationic polymerization initiator including a cationic moiety and an anionic moiety containing a boron atom; and (C) a light-shielding material.

First claim

The invention claimed is:

1. A photosensitive resin composition comprising components as follows:
(A) a cationically polymerizable compound at least comprising a compound containing an alicyclic epoxy group and devoid of ester bonds;
(B) a photo-cationic polymerization initiator including a cationic moiety and an anionic moiety containing a boron atom;
(C) a light-shielding material; and
(D) a hydroxyl-containing compound having a molecular weight of 500 or more, wherein the component (D) comprises at least one of a hydroxyl-containing compound having a polycarbonate skeleton in the molecule, a hydroxyl-containing compound having a polyester skeleton in the molecule, or a hydroxyl-containing compound having a polydiene skeleton in the molecule.

2. The photosensitive resin composition according to claim 1 , wherein the compound containing an alicyclic epoxy group and devoid of ester bonds in the component (A) is a compound represented by Formula (a-1):

wherein R 1 to R 18 are identical or different and are independently selected from the group consisting of a hydrogen atom, a halogen atom, a hydrocarbon group optionally containing at least one of oxygen and halogen, and an optionally substituted alkoxy group; and X is selected from a single bond and a linkage group, excluding ester-bond-containing linkage groups.

3. The photosensitive resin composition according to claim 2 , wherein the anionic moiety of the component (B) is an anion represented by Formula (1):
[Chem. 2]
[(R) n BF 4−n ] −   (1)

wherein R represents a monovalent hydrocarbon group or a monovalent fluorinated hydrocarbon group; and n represents an integer from 1 to 4.

4. The photosensitive resin composition according to claim 2 , wherein the anionic moiety of the component (B) is an anion represented by Formula (2):

wherein X1 to X4 are identical or different, each represent an integer from 0 to 5, and the total of all of X1 to X4 is one or more.

5. The photosensitive resin composition according to claim 2 , wherein the component (C) is a carbon black.

6. A cured product of the photosensitive resin composition according to claim 2 .

7. The photosensitive resin composition according to claim 1 , wherein the anionic moiety of the component (B) is an anion represented by Formula (1):
[Chem. 2]
[(R) n BF 4−n ] −   (1)

wherein R represents a monovalent hydrocarbon group or a monovalent fluorinated hydrocarbon group; and n represents an integer from 1 to 4.

8. The photosensitive resin composition according to claim 7 , wherein the anionic moiety of the component (B) is an anion represented by Formula (2):

wherein X1 to X4 are identical or different, each represent an integer from 0 to 5, and the total of all of X1 to X4 is one or more.

9. The photosensitive resin composition according to claim 7 , wherein the component (C) is a carbon black.

10. A cured product of the photosensitive resin composition according to claim 7 .

11. The photosensitive resin composition according to claim 1 , wherein the anionic moiety of the component (B) is an anion represented by Formula (2):

wherein X1 to X4 are identical or different, each represent an integer from 0 to 5, and the total of all of X1 to X4 is one or more.

12. The photosensitive resin composition according to claim 11 , wherein the component (C) is a carbon black.

13. A cured product of the photosensitive resin composition according to claim 11 .

14. The photosensitive resin composition according to claim 1 , wherein the component (C) is a carbon black.

15. A cured product of the photosensitive resin composition according to claim 14 .

16. A cured product of the photosensitive resin composition according to claim 1 .

17. An optical component comprising the cured product according to claim 16 .
