Abstract

An epoxy (meth)acrylate compound represented by general formula (1): where at least one of R 1 to R 5 has a structure represented by formula (2): * denotes the bonding position to a carbon atom that constitutes the benzene ring to which R 1 to R 5 are bonded in formula (1), R 7 denotes a hydrogen atom or a methyl group, the remainder of R 1 to R 5 are each independently selected from the group consisting of hydrogen atoms, alkyl groups and alkoxy groups having 1-6 carbon atoms, and R 6 denotes a hydrogen atom or a methyl group. In the epoxy (meth)acrylate compound, the content of halogen atoms is 100 ppm by mass or less. A curable composition for forming a protective film for an electrically conductive pattern obtained by mixing the epoxy (meth)acrylate compound with a photopolymerization initiator and at least one type of monomer or oligomer that contains a (meth)acryloyl group.

Claims (8)

1. An epoxy (meth)acrylate compound represented by Formula (1), and having a halogen atom content of 100 ppm by mass or less:

(wherein, at least one of R 1 to R 5 has a structure represented by Formula (2); the remainders of R 1 to R 5 are each independently selected from a group consisting of a hydrogen atom, at alkyl group having 1 to 6 carbon atoms; and an alkoxy group having 1 to 6 carbon atoms; and R 6 represents a hydrogen atom or a methyl group),

(wherein, * represents a bonding position to a carbon atom that constitutes the benzene ring to which R 1 to R 5 are bonded in Formula (1); and R 7 represents a hydrogen atom or a methyl group).

2. An epoxy (meth)acrylate compound according claim 1 , wherein the epoxy (meth)acrylate compound is a compound represented by Formula (3) or Formula (4):

(wherein, R 8 represents a hydrogen atom or a methyl group),

(wherein, R 9 represents a hydrogen atom or a methyl group).

3. A curable composition comprising: an epoxy (meth)acrylate compound according to claim 1 , at least one of monomers and oligomers containing a (meth)acryloyl group, and a photopolymerization initiator.

4. A curable composition comprising: an epoxy (meth)acrylate compound according to claim 2 , at least one of monomers and oligomers containing a (meth)acryloyl group, and a photopolymerization initiator.
