摘要： To provide an active-energy-ray-curable resin composition that exhibits high bonding strength even to plastic films that are difficult to bond such as untreated PET films, fluorine-based films, and polycarbonate films, which are referred to as difficult-to-bond films, and that can maintain the bonding strength even under wet heat conditions; an adhesive including the resin composition; and a laminate film obtained by using the adhesive. The essential components contained are a (meth)acrylate compound (A), a polyester resin (B), and a polymerization initiator (D), the (meth)acrylate compound (A) having a weight-average molecular weight (Mw) in a range of 5,000 to 30,000 and including, in a molecular structure, a (meth)acryloyl group and a polyester moiety, and the polyester resin (B) having an acid value in a range of 40 to 90 mgKOH/g.
