PROBLEM TO BE SOLVED: To provide an adhesive composition for a dry laminate of a PET film and a metal foil, which is suitable for production of a shielding material by laminating previously a PET film to a metal foil to produce a laminated film and processing the film into a mesh structure by etching to give transparency thereto, the composition further being excellent in adhesiveness and susceptibility to etching. SOLUTION: The adhesive composition comprises, in terms of the solid contents, 100 pts.wt. of a thermoplastic polyester resin having a glass transition temperature of 0-40°C, a number average molecular weight of 2,000-10,000 and an average number of hydroxy group of 2.01-2.5 per molecule and 1-30 pts.wt. of hexamethylene diisocyanate incorporated therein. The laminated film is produced by dry lamination of a PET film and a metal foil using the adhesive composition. COPYRIGHT: (C)2004,JPO |
