Laminated film |
摘要 |
A laminated film includes a resin layer provided on at least one surface of a thermoplastic resin film substrate, wherein the resin layer comprises an acrylic-modified polyester whose acrylic resin component has a glass-transition temperature of not lower than 67° C. and a sugar alcohol and/or a sugar alcohol derivative; the mass ratio of the acrylic-modified polyester to the sugar alcohol and the sugar alcohol derivative (the mass of the acrylic-modified polyester/the total mass of the sugar alcohol and the sugar alcohol derivative) is from 75/25 to 97/3; the total content of the acrylic-modified polyester and the sugar alcohol and sugar alcohol derivative is 65% by mass or more based on the total resin layer; and the haze value of the laminated film is not more than 2.0%. |

1. A laminated film comprising a resin layer provided on at least one surface of a thermoplastic resin film substrate, wherein
the resin layer comprises 1) a fluorochemical surfactant in an amount of from 0.01% by mass to 0.30% by mass based on the total mass of a resin composition forming the resin layer, 2) an acrylic-modified polyester whose acrylic resin component has a glass-transition temperature of not lower than 67° C. and 3) a sugar alcohol and/or a sugar alcohol derivative; a mass ratio of the acrylic-modified polyester to the sugar alcohol and the sugar alcohol derivative (mass of the acrylic-modified polyester/total mass of the sugar alcohol and the sugar alcohol derivative) is from 90/10 to 97/3; total content of the acrylic-modified polyester, the sugar alcohol, and the sugar alcohol derivative is 65% by mass or more based on the total resin layer; and haze value of the laminated film is not more than 2.0%. |
