Abstract
A laminated adhesive thermoplastic resin film includes a laminated layer containing a polyester resin (A) and a polyester resin (B) different from each other in glass transition temperature and a melamine-based crosslinking agent (C) as 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) is 110° C. or higher; the glass transition temperature of the polyester resin (B) 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 based on the weight of the polyester resin (A) and the polyester resin (B).
