Disclosed is a laminated film—which comprises a resin layer provided to at least one surface of a thermoplastic resin film substrate—wherein said resin layer contains a sugar alcohol and/or a sugar alcohol derivative, and an acrylic-modified polyester of which the glass transition point of the acrylic resin component is at least 67°C; the mass ratio (mass of acrylic-modified polyester/total mass of sugar alcohol and sugar alcohol derivative) of said acrylic-modified polyester to said sugar alcohol and said sugar alcohol derivative is between 75/25 and 97/3 inclusive; the total contained amount of said acrylic-modified polyester, said sugar alcohol, and said sugar alcohol derivative is at least 65 mass% of said resin layer overall; and the haze value of said laminated film is no more than 2.0%. As a result, provided is a laminated film having excellent transparency and oligomer suppressiveness in a heat-treating step. |
