(57) [Problem] To provide a strong adhesive force by combining an organic primer and a water-based adhesive for hardly adherent plastics. [Constitution] Polyvinyl alcohol (PVA), polyvinyl acetate (PVA) c) forming a primer thin film comprising at least one or more selected from polyvinyl butyral (PVB) and polyacrylic acid, and then forming a polyvinyl alcohol, polyvinyl acetate, acryl / vinyl acetate copolymer, Aqueous adhesive comprising at least one or more selected from acrylic / silicone copolymer, ethylene / vinyl alcohol copolymer (EVOH), ethylene / vinyl acetate copolymer (EVA), and styrene / acrylic copolymer Thereby, a structure having a strong adhesive force can be obtained when the primer-treated hardly-adhesive plastic members are bonded to each other or when the easily-adhesive plastic members are bonded to each other. |
