<p>[Problem to be solved] This invention provides a laminated adhesive film excellent in the adhesive property to a metal layer, especially excellent in the adhesive property to a metalized layer, the adhesive property after a heat and wet test and the adhesive property after solvent tests using various chemicals. [Solution] A laminated adhesive thermoplastic resin film, comprising a laminated layer containing two polyester resins different from each other in glass transition temperature and a melamine-based crosslinking agent (C) as main components and having a surface energy of 48 to 55 mN/m, formed at least on one surface of the thermoplastic resin film, wherein the glass transition temperature of the polyester resin (A) higher in glass transition temperature is 110°C or higher; the glass transition temperature of the polyester resin (B) lower in glass transition temperature is 60°C to lower than 110°C; and the amount of the melamine-based crosslinking agent (C) is 75 to 200 parts by weight per 100 parts by weight in total of said two polyester resins.</p> |
