Abstract:
To provide a decorative film in which swelling of a layer containing a fluorinated polymer is suppressed and adhesion of the layer containing the fluorinated polymer is excellent; and a method for producing a three-dimensional molded product provided with a decorative film. The decorative film is characterized by comprising a base film containing a plasticizer; a first layer containing at least one member selected from the group consisting of a polyvinylidene fluoride, a polymethyl methacrylate and a polyurethane; and a second layer containing a fluorinated polymer comprising units based on a fluoroolefin and units based on at least one type of non-fluorinated monomer selected from the group consisting of a vinyl ether, a vinyl ester, an allyl ether and an allyl ester, in this order; wherein the water contact angle of the surface on the first layer side of the second layer is larger than the water contact angle on the second layer side of the first layer, and the difference between the water contact angle of the surface on the first layer side of the second layer and the water contact angle of the surface on the second layer side of the first layer is more than 0° and at most 50°.
