Patent number: 10611934Abstract: A permanent adhesive composition for image sensors which provides an adhesive layer having excellent heat resistance and thermal shock resistance, and a bonding method and laminate using the permanent adhesive composition. The permanent adhesive composition for image sensors contains a thermosetting or photocurable resin containing a specific bifunctional (meth)acrylic acid ester-derived structural unit, a polymerizable monomer, and an antioxidant, and used to bond together a substrate and a support for the substrate. The bonding method includes bonding together a substrate and a support for the substrate using the permanent adhesive composition. The laminate is provided with a substrate, a support for the substrate, and an adhesive layer for bonding the substrate and the support together, and the adhesive layer is formed of the permanent adhesive composition.Type: GrantFiled: December 21, 2016Date of Patent: April 7, 2020Assignees: TOKYO OHKA KOGYO CO., LTD., NIPPON STEEL CHEMICAL & MATERIAL CO., LTD.Inventors: Tokunori Yamadaya, Hiroaki Takeuchi, Masatoshi Maeda, Kentaro Hayashi, Masayoshi Isozaki
