<p>PROBLEM TO BE SOLVED: To improve printability and thermal fusion bonding laminability by integrally laminating coating layers each having an intrinsic viscosity of a specific range, and containing an amorphous polyester resin on both surfaces of a core layer made of a resin composition containing an amorphous polyester resin. SOLUTION: Coating layers 3 each having an intrinsic viscosity of 0.70 to 0.76 and containing an amorphous polyester resin are integrally laminated on both surfaces of a core layer 2 containing one or more types of a modifier selected from a synthetic rubber such as an ethylene-vinyl acetate copolymer, an ethylene-propylene rubber or the like and a styrene resin such as an acrylonitrile-butadiene-styrene copolymer, a methyl methacrylate-butadiene- styrene copolymer or the like in an amorphous copolymerization polyester resin composition obtained by substituting 10 to 70% of an ethylene glycol component of a polyethylene terephthalate with a cyclohexanedimethanol.</p> |
