Abstract: There is provided a water-based resin composition that contains a polymer (A) containing, as essential raw materials, a hydrogenated polybutadiene (a1) with an iodine value in the range of 5 to 25, a monomer (a2) with an acid group, and a monomer (a3) with a hydroxy group, a basic compound (B), and an aqueous medium (C), wherein the hydrogenated polybutadiene (a1) constitutes 4% to 38% by mass of the raw materials of the polymer (A), and the polymer (A) has an acid value in the range of 10 to 65 mgKOH/g. A water-based resin composition of the present invention has high storage stability and forms a coating film with good physical properties, such as high adhesiveness to various substrates and high blocking resistance, and is therefore suitably used in a water-based paint.

Abstract: 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.
