Abstract:
Provided are a film which can be decorated even against a three-dimensional shape, is excellent in moldability during decoration (adhesion) on an adherend, is able to reduce concaves and convexes with a variety of sizes which the adherend surface has, and makes an appearance quality favorable; and a decorative molded product having the film. The film is a film including a layer containing a thermoplastic resin, wherein when a highest temperature of glass transition temperatures of the film is designated as Tg [+ C], a temperature T [° C.] at which an elongation at break is 50% or more exists in a range of Tg to (Tg+50 [° C.]), and when, with respect to concaves and convexes of an abrasive grain surface of a polyester film sheet having, as an abrasive grain, aluminum oxide having a grain size of 12 μm coated thereon, an amplitude relative to a spatial frequency f is designated as A1(f); with respect to concaves and convexes of a film surface when adhering the film to the abrasive grain surface at any temperature of the range of Tg to (Tg+50 [° C.]) and a pressure of 0.3 MPa, an amplitude relative to the spatial frequency f is designated as A2(f); and a ratio of A2(f) to A1(f) is designated as ϕ(f)=A2(f)/A1(f), a minimum value fc of spatial frequencies where ϕ(f) is 0.1 is 2.0 mm−1 or less.
