The film has excellent winding properties during processing, has high design properties and excellent fingerprint wipe-off properties for the surface of product members (molded members after molding and decoration) when the film is used as a transfer foil for molding. ## Claims ### Claim 1 A molding film comprising mainly a cyclic olefin-based resin, wherein when an X surface represents one surface of the film and a Y surface represents another surface of the film, the X surface and the Y surface both have a surface glossiness of 50% or less, and a ratio between thermal shrinkage in a transverse direction and thermal shrinkage in a machine direction at 80° C. satisfies −2< the thermal shrinkage in the transverse direction/the thermal shrinkage in the machine direction <−0.5. ### Claim 2 (depends on 1) The molding film according to claim 1, wherein when the X surface represents a surface having a surface glossiness equal to or greater than a surface glossiness of the Y surface, the X surface has a surface roughness SRa of not less than 100 nm and not more than 1500 nm and the Y surface has a surface roughness SRa of not less than 100 nm and not more than 2000 nm. ### Claim 3 (depends on 1) The molding film according to claim 1, which comprises an A layer and a B layer, wherein when the A layer contains a cyclic olefin-based resin of not less than 50% by mass and not more than 99% by mass and a polyethylene-based resin and/or polypropylene-based resin of not less than 1% by mass and not more than 40% by mass in total with respect to 100% by mass of the layers in total; and the B layer contains a cyclic olefin-based resin of not less than 50% by mass and not more than 99% by mass and a polyethylene-based resin and/or polypropylene-based resin of not less than 1% by mass and not more than 40% by mass in total with respect to 100% by mass of the layers in total, the A layer is greater than the B layer in terms of a total content (% by mass) of the polyethylene-based resin and/or polypropylene-based resin in the layers. ### Claim 4 (depends on 1) A molding transfer foil comprising the molding film according to claim 1, a design layer and an adhesive layer formed in this order on the molding film, wherein when a Y surface represents a surface having a surface glossiness equal to or lower than a surface glossiness of an X surface, the Y surface is an outmost surface of one side of the molding transfer foil. ### Claim 5 (depends on 2) The molding film according to claim 2, which comprises an A layer and a B layer, wherein when the A layer contains a cyclic olefin-based resin of not less than 50% by mass and not more than 99% by mass and a polyethylene-based resin and/or polypropylene-based resin of not less than 1% by mass and not more than 40% by mass in total with respect to 100% by mass of the layers in total; and the B layer contains a cyclic olefin-based resin of not less than 50% by mass and not more than 99% by mass and a polyethylene-based resin and/or polypropylene-based resin of not less than 1% by mass and not more than 40% by mass in total with respect to 100% by mass of the layers in total, the A layer is greater than the B layer in terms of a total content (% by mass) of the polyethylene-based resin and/or polypropylene-based resin in the layers. ### Claim 6 (depends on 2) A molding transfer foil comprising the molding film according to claim 2, a design layer and an adhesive layer formed in this order on the molding film, wherein when a Y surface represents a surface having a surface glossiness equal to or lower than a surface glossiness of an X surface, the Y surface is an outmost surface of one side of the molding transfer foil. ### Claim 7 (depends on 3) A molding transfer foil comprising the molding film according to claim 3, a design layer and an adhesive layer formed in this order on the molding film, wherein when a Y surface represents a surface having a surface glossiness equal to or lower than a surface glossiness of an X surface, the Y surface is an outmost surface of one side of the molding transfer foil.
