Document Type and Number:
Japanese Patent JP7452265
Kind Code:
B2
Abstract:
To provide an adhesive that contains epoxy resin and can form a cured product to exhibit high elongation at -40°C.SOLUTION: An adhesive contains an acryl monomer having two or more (meth)acryloyl groups, epoxy resin having two or more epoxy groups, and a curing agent containing a compound having a nucleophilic reactive group reactable with an epoxy group and/or a (meth)acryloyl group, and a block copolymer elastomer. The block copolymer elastomer has a first block including a monomer unit derived from a first monomer to form a homopolymer having a glass transition temperature of 80°C or higher when polymerized alone, and a second block including a monomer unit derived from a second monomer to form a homopolymer having a glass transition temperature of -30°C or lower when polymerized alone.SELECTED DRAWING: None
