Abstract

A novel compound having satisfactory sensitivity (base generating performance), a photosensitive resin composition containing the compound as a photo-initiator, and a cured product of the composition are provided. Specifically, a compound represented by general formula (1) (compound (1)), a photosensitive resin composition containing (A) a photo-initiator including at least one compound (1) and (B) a photosensitive resin are provided. Preferred are the compound (1) in which R 1 is an unsubstituted or substituted C6-C20 aromatic hydrocarbon group, the compound (1) in which at least one of R 5 , R 6 , R 7 , R 8 , R 9 , R 10 , and R 11 is nitro, and the compound (1) in which n is 0.

The symbols in general formula (1) are as defined in the description.

First claim

The invention claimed is:

1. A compound represented by general formula (1):

wherein R 1 represents an unsubstituted or substituted aliphatic hydrocarbon group having 1 to 20 carbon atoms or an unsubstituted or substituted aromatic hydrocarbon group having 6 to 20 carbon atoms,
R 2 and R 3 are taken together to form a ring containing a nitrogen atom and a carbon atom,
R 4 represents an unsubstituted or substituted aliphatic hydrocarbon group having 1 to 20 carbon atoms, an unsubstituted or substituted aromatic hydrocarbon group having 6 to 20 carbon atoms, or an unsubstituted or substituted heterocyclic group having 2 to 20 carbon atoms,
R 5 , R 6 , R 7 , R 8 , R 9 , and R 11 each independently represent a hydrogen atom, a cyano group, a halogen atom, or an unsubstituted aliphatic hydrocarbon group having 1 to 20 carbon atoms, and
R 10 is a nitro group.

2. The compound according to claim 1 , wherein R 1 in general formula (1) is an unsubstituted or substituted aromatic hydrocarbon group having 6 to 20 carbon atoms.

3. The compound according to claim 1 , selected from the group consisting of:

4. The compound according to claim 1 , wherein R 1 in general formula (1) is a substituted or unsubstituted phenyl group.

5. A photosensitive resin composition comprising
(A) a photo-initiator comprising at least one compound represented by general formula (1):

wherein R 1 represents an unsubstituted or substituted aliphatic hydrocarbon group having 1 to 20 carbon atoms, or an unsubstituted or substituted aromatic hydrocarbon group having 6 to 20 carbon atoms,
R 2 and R 3 are taken together to form a ring containing a nitrogen atom and a carbon atom,
R 4 represents an unsubstituted or substituted aliphatic hydrocarbon group having 1 to 20 carbon atoms, an unsubstituted or substituted aromatic hydrocarbon group having 6 to 20 carbon atoms, or an unsubstituted or substituted heterocyclic group having 2 to 20 carbon atoms,
R 5 , R 6 , R 7 , R 8 , R 9 , and R 11 each independently represent a hydrogen atom, a cyano group, a halogen atom, or an unsubstituted aliphatic hydrocarbon group having 1 to 20 carbon atoms, and
R 10 is a nitro group; and

(B) a photosensitive resin.

6. The photosensitive resin composition according to claim 5 , wherein R 1 in general formula (1) is a substituted or unsubstituted phenyl group.

7. A cured product obtained by irradiating the photosensitive resin composition according to claim 5 with energy rays.
