The invention relates to a composition for forming an adhesive layer, an adhesive layer, a manufacturing method for the adhesive layer, a composite material, a sheet, a heat dissipation member, an electronic device, a battery, a capacitor, an automobile component and a machine mechanism component, and the composition for forming the adhesive layer contains a polyvinyl acetal resin and a compound having an oxazoline group.

The present invention is to provide an adhesive composition which comprises a copolymer A which contains a recurring unit having a cyclic ether structure and a recurring unit having a benzophenone structure, and a copolymer B which contains a recurring unit having a betaine structure and a recurring unit having a hydroxyl group, a cured product thereof, and a method for producing the cured product. The adhesive composition of the present invention is capable of curing in water, has high hydrophilicity, and is capable of forming a cured product having an excellent ability to inhibit adhesion of biological substances.

Disclosed are curable adhesive compositions comprising hydroxyl functional polymers and silane functionalized resins. Such adhesive compositions are capable of providing unexpected properties for various uses and end products. The adhesive may be used for woodworking, automotive, textile, appliances, electronics, bookbinding, and packaging. Suitable substrates can be metal, polymer film, plastics, wood, glass, ceramic, paper, and concrete.
