A composition for forming a separation layer that separates a support base that transmits light from a laminate including the support base, a substrate, the separation layer and an adhesive layer between the support base and the substrate by irradiating the separation layer with light from the support base side and modifying the separation layer. The composition contains a resin component which has a phenol skeleton.

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.
