The present invention is an aqueous solution that can be used as a primer that greatly improves the adhesion between the substrate and the cured coating film of the active energy ray-curable composition, even if it is a difficult-to-adhere substrate such as a polyester film. It is an object to provide a resin composition. In the present invention, an aqueous resin composition comprising a composite resin containing a vinyl ester resin and a urethane resin having an aromatic ring, an aqueous resin, and an aqueous medium, wherein the vinyl ester resin is a novolac epoxy resin and A reaction product of at least one epoxy resin selected from the group consisting of bisphenol-type epoxy resins and a compound having an acid group and a polymerizable unsaturated group, wherein the urethane resin is a polyol having an aromatic ring and a hydrophilic group An aqueous resin composition is used, which is a reaction product of a polyol containing a polyol having a polyisocyanate. |
