Abstract
A transparent laminated film is described, which has excellent chemical resistance and surface hardness, is glossy even after heating and which has a low haze value, and a laminated molded article that uses the film.
Claims15
A laminated film comprising:
- a layer of a polymer blend (X) comprising a vinylidene fluoride resin (F) and an acrylic resin (A1);
- and
- a layer of an acrylic resin composition (Y),
- wherein
- the acrylic resin (A1) has a glass transition temperature of 95 to 120° C.,
- the vinylidene fluoride resin (F) has a hetero linkage rate of no greater than 10%, and
- the laminated film satisfies the following conditions (1) to (3):
- (1) a haze value of no greater than 2 after the film is heated to 180° C. and then allowed to naturally cool until the temperature drops to 25° C.;
- (2) a pencil hardness of the layer of the polymer blend (X) is HB or harder;
- and
- (3) a heat of crystal fusion of the polymer blend (X) as determined using a differential scanning calorimeter is 22.1 to 40 J/g.
