Abstract

See full text

Provided are an adhesive composition that is halogen-free and that can satisfy flame retardancy without impairing adhesiveness or solder heat resistance, and a laminate and a flexible printed wiring board using the same. The adhesive resin composition contains an epoxy resin; a thermoplastic resin; a benzoxazine compound; a halogen-free flame retardant; and a curing agent, in which at least one of the epoxy resin and the thermoplastic resin contains a phosphorus-containing resin, and the phosphorus content in the solid portion of the adhesive resin composition is 2.5% by mass or more. Preferably, a phosphorus-containing epoxy resin is used as the epoxy resin, a thermoplastic resin containing 10% to 70% by mass of a phosphorus-containing polyester is used as the thermoplastic resin, and the amount of benzoxazine is 5 to 25 parts by mass and the amount of halogen-free flame retardant is 1 to 30 parts by mass per 100 parts of the resins.
