|1. (WO2018021224) EPOXY (METH)ACRYLATE COMPOUND AND CURABLE COMPOSITION CONTAINING SAME|
|Applicants:||SHOWA DENKO K.K.
|Title:||EPOXY (METH)ACRYLATE COMPOUND AND CURABLE COMPOSITION CONTAINING SAME|
[Problem] To provide an epoxy (meth)acrylate compound that serves as a material for a protective film that is unlikely to cause migration to an electrically conductive pattern, and a curable composition containing the epoxy (meth)acrylate compound. [Solution] Provided is an epoxy (meth)acrylate compound which is characterized by being represented by general formula (1) and in which the content of halogen atoms, which are impurities, is 100 ppm by mass or less. In addition, provided is a curable composition for forming a protective film for an electrically conductive pattern, the curable composition being obtained by mixing this epoxy (meth)acrylate compound with a photopolymerization initiator and at least one type of monomer or oligomer that contains a (meth)acryloyl group. Formula (1) (At least one of R1 to R5 has a structure represented by formula (2), and the remainder of R1 to R5 are each independently selected from the group consisting of hydrogen atoms and alkyl groups and alkoxy groups having 1-6 carbon atoms. R6 denotes a hydrogen atom or a methyl group.) Formula (2) (＊ denotes the bonding position to a carbon atom that constitutes the benzene ring to which R1 to R5 are bonded in formula (1), and R7 denotes a hydrogen atom or a methyl group.)
