     (Decorative Film) 
     A decorative film according to the embodiment of the present disclosure includes a base material and an optical thin film coloring by optical interference or structural color. 
     Specifically, the decorative film according to the embodiment of the present disclosure includes a base material and a reflective layer having a convex structure, in which, in a cross section obtained by cutting the convex structure in a direction perpendicular to a plane direction of the decorative film, in a case where a direction in which an average Φ AVE  of positive tilt angles is the largest is defined as a first direction and a direction in which the average Φ AVE  of the positive tilt angles is the smallest is defined as a second direction, the decorative film has a region A in which Φ AVE  in the first direction is 3° or more and Φ AVE  in the second direction is less than 3°. 
     An application of the decorative film according to the embodiment of the present disclosure is not particularly limited, and specific examples thereof include a decoration of electronic devices (for example, wearable devices and smartphones), home appliances, audio products, computers, displays, in-vehicle products, watches, accessories, optical parts, doors, window glasses, and building materials. Among these, the decorative film according to the embodiment of the present disclosure can be suitably used for a decoration of electronic devices (for example, wearable devices and smartphones). In addition, since the decorative film according to the embodiment of the present disclosure has excellent three-dimensional moldability, the decorative film according to the embodiment of the present disclosure is suitable as a decorative film for molding, which is used for molding such as three-dimensional molding and insert molding, and more suitable as a decorative film for three-dimensional molding. 
     In the related art, as a surface decoration used in articles such as home appliances, electronic apparatuses, and mobile phones, for example, printing, painting, vapor deposition, or plating has been used. However, for example, from the aspects of problems such as functionality addition and environmental load, and the possibility of replacement, a decoration technique by using a decorative film has been widely used. On the other hand, new designability is required from the widespread preference of users. In particular, change in color (for example, a tint and a fine hue) depending on a viewing angle is one of required designs, and a need for introducing the decoration technique to obtain the designs has been required. In addition, in JP2001-105795A, a hot stamp foil in which a cholesteric liquid crystalline polymer layer is laminated as a transfer layer is disclosed, but since reflected color changes depending on a viewing angle, a uniform tint cannot be obtained. In addition, in JP2017-97114A, it is disclosed that retroreflective property is improved by subjecting a cholesteric liquid crystal layer to an uneven processing, but there is no disclosure of its use as a decorative film and its effects. 
     As a result of intensive studies by the present inventors, it has been found that, according to the decorative film including the above-described configuration, a decorative film which is useful as a material for a decorative molded article having a rich tint change depending on a viewing direction. In the present disclosure, the “having a rich tint change depending on a viewing direction” means that, for example, there is a large change in tint between a case where an object is viewed from an angle perpendicular to a surface direction of the object and a case where the object is viewed at an angle of 45° with respect to the surface direction of the object. The above-described effect is preferable in that impact of a design can be improved. 
     Hereinafter, the decorative film according to the embodiment of the present disclosure will be described in detail. 
     &lt;Base Material&gt; 
     The decorative film according to the embodiment of the present disclosure has a base material. The base material may be a support. As the base material, for example, a known base material in the related art as a base material used for molding such as three-dimensional molding and insert molding can be used without particular limitation, and may be appropriately selected according to suitability for molding. In addition, a shape and a material of the base material are not particularly limited, and may be appropriately selected as desired. From the viewpoint of ease of molding and chipping resistance, the base material is preferably a resin base material, and more preferably a resin film. 
     Specific examples of the base material include a resin film including a resin such as polyethylene terephthalate (PET), polyethylene naphthalate (PEN), an acrylic resin, a urethane resin, a urethane-acrylic resin, polycarbonate (PC), an acrylic-polycarbonate resin, triacetyl cellulose (TAC), cycloolefin polymer (COP), and acrylonitrile/butadiene/styrene copolymer resin (ABS resin). Among these, from the viewpoint of moldability and strength, the base material is preferably polyethylene terephthalate (PET), an acrylic resin, polycarbonate, or polypropylene, and more preferably polyethylene terephthalate (PET), an acrylic resin, or polycarbonate. In addition, the base material may be a laminated resin base material having two or more layers. Preferred examples thereof include a laminated film including an acrylic resin layer and a polycarbonate layer. 
     The base material may contain other additives as necessary. Examples of such additives include lubricants (for example, mineral oil, hydrocarbons, fatty acids, alcohols, fatty acid esters, fatty acid amides, metallic soaps, natural waxes, and silicone), inorganic flame retardants (for example, magnesium hydroxide and aluminum hydroxide), a halogen-based organic flame retardant, a phosphorus-based organic flame retardant, organic or inorganic fillers (for example, metal powder, talc, calcium carbonate, potassium titanate, glass fibers, carbon fibers, and wood powder), an antioxidant, an ultraviolet inhibitor, a dispersant, a coupling agent, a foaming agent, a colorant, and engineering plastics other than the above-described resins. Examples of the engineering plastics include polyolefins, polyesters, polyacetals, polyamides, and polyphenylene ethers. 
     As the base material, a commercially available product may be used. Examples of the commercially available product include TECHNOLLOY (registered trademark) series (acrylic resin film or acrylic resin/polycarbonate resin laminated film, manufactured by Sumitomo Chemical Co., Ltd.), ABS films (manufactured by Okamoto Industries, Inc.), ABS sheets (manufactured by SEKISUI SEIKEI CO., LTD.), Teflex (registered trademark) series (PET film, manufactured by TEIJIN FILM SOLUTIONS LIMITED), Lumirror (registered trademark) easily moldable type (PET film, manufactured by TORAY INDUSTRIES, INC), and Purethermo (polypropylene film, manufactured by Idemitsu Kosan Co., Ltd.). 
     A thickness of the base material is determined according to, for example, the application of a molded product to be produced and handleability, and is not particularly limited. The lower limit of the thickness of the base material is preferably 1 μm or more, more preferably 10 μm or more, still more preferably 20 μm or more, and particularly preferably 30 μm or more. The upper limit of the thickness of the base material is preferably 500 μm or less, more preferably 200 μm or less, and particularly preferably 100 μm or less. 
     &lt;Reflective Layer&gt; 
     The decorative film according to the embodiment of the present disclosure includes a reflective layer having a convex structure, in which, in a cross section obtained by cutting the convex structure in a direction perpendicular to a plane direction of the decorative film, in a case where a direction in which an average Φ AVE  of positive tilt angles is the largest is defined as a first direction and a direction in which the average Φ AVE  of the positive tilt angles is the smallest is defined as a second direction, the decorative film has a region A in which Φ AVE  in the first direction is 3° or more and Φ AVE  in the second direction is less than 3°. 
     A method of determining the above-described first direction and the above-described second direction in the present disclosure is shown below. 
     The above-described convex structure is cut in an arbitrary plane (that is, 360° existing as a direction) perpendicular to a plane direction of the decorative film, and a direction in which an average Φ AVE  of positive tilt angles is the largest and a direction in which the average Φ AVE  of the positive tilt angles is the smallest are determined. 
     As a method of calculating the average Φ AVE  of the positive tilt angles, with regard to a region which includes the above-described convex structure and has a size equal to or larger than a circle having a radius of 150 μm, an average value of only a portion where the tilt angle of the convex structure portion is 0° or more in a cross section obtained by cutting the convex structure in one direction is defined as the above-described average Φ AVE  of the positive tilt angles. A portion where the tilt angle is negative is excluded from the calculation of the average Φ AVE  of the positive tilt angles. 
     In addition, the above-described positive tilt angle is an angle with respect to the plane direction of the decorative film, and a portion of more than 90° and less than 180° is a tilt angle opposite to the measurement direction of the positive tilt angle and is a portion of less than 90° and more than 0° of a negative tilt angle. 
     As the method of calculating the average Φ AVE  of the positive tilt angle, specifically, a microtome (for example, RX-860 manufactured by YAMATO KOHKI INDUSTRIAL CO., LTD.) is used to cut the decorative film on an arbitrary plane in a direction (360° existing as a direction) perpendicular to the plane direction of the decorative film. The cutting direction can be predicted to some extent by observing the surface of the decorative film with a microscope (for example, BX53M manufactured by Olympus Corporation). A cross-sectional shape is measured by observing the cut cross section with a scanning electron microscope (for example, SU3800 manufactured by Hitachi High-Tech Corporation), and Φ AVE  is calculated as described above. 
     In addition, examples of a method for measuring the cross-sectional shape other than the above-described method include a method of measuring a surface shape of the convex structure using a laser microscope (for example, VK-X1000 manufactured by KEYENCE CORPORATION), and in a case where the convex structure can be measured in three dimensions, the cross-sectional shape may be calculated from a three-dimensional shape. 
     More specifically, the description will be made with reference to  FIG.  11    and  FIGS.  12 A to  12 C . 
       FIG.  11    is an enlarged schematic view of a region of a reflective layer having a convex structure in an example of the decorative film according to the embodiment of the present disclosure. 
     As the convex structure of the reflective layer in  FIG.  11   , a plurality of linear convex structures in which a vertical direction in  FIG.  11    is a longitudinal direction are formed. 
     Straight lines A, B, and C in  FIG.  11    indicate directions for cutting the above-described convex structure.  FIGS.  12 A to  12 C  show cross sections obtained by cutting the above-described convex structure in the direction indicated by the straight line A (direction A), the direction indicated by the straight line B (direction B), or the direction indicated by the straight line C (direction C). In  FIGS.  12 A to  12 C , A shows a cross section of the above-described convex structure cut in the direction A, B shows a cross section of the above-described convex structure cut in the direction B, and C shows a cross section of the above-described convex structure cut in the direction C, respectively. 
     As shown in  FIG.  12 A , the cross section of the convex structure in the direction A has tilt angles Φ of 30° and −20°. A bar indicated by a 1  shows a distribution of the positive tilt angle, and a bar indicated by a 2  shows a distribution of the negative tilt angle. 
     In the direction A, the average Φ AVE  of the positive tilt angles is determined as 30°. As described above, the calculation is performed excluding the negative tilt angle of −20°. 
     In addition, as shown in  FIG.  12 B , the cross section of the convex structure in the direction B has tilt angles Φ of 20° and −10°. A bar indicated by b 1  shows a distribution of the positive tilt angle, and a bar indicated by b 2  shows a distribution of the negative tilt angle. 
     In the direction B, the average Φ AVE  of the positive tilt angles is determined as 20°. As described above, the calculation is performed excluding the negative tilt angle of −10°. 
     Furthermore, as shown in  FIG.  12 C , the cross section of the convex structure in the direction C is flat, and the tilt angle Φ is 0°. 
     In the direction C, the average Φ AVE  of the positive tilt angles is determined as 0°. 
     The same operation is performed at 360° (in a case where the first direction and the second direction are predicted to some extent, the operation can be omitted) to determine the first direction in which the average Φ AVE  of the positive tilt angles is the largest and the second direction in which the average Φ AVE  of the positive tilt angles is the smallest. 
     In the region having the convex structure shown in  FIG.  11    and  FIGS.  12 A to  12 C , Φ AVE  in the first direction is 30° and Φ AVE  in the second direction is 0°. 
     In the present disclosure, the convex structure means that convex undulations are formed with respect to a specific plane. 
     In the decorative film according to the embodiment of the present disclosure, it is sufficient that the above-described reflective layer has the convex structure, and the surface of the decorative film itself may be flat (preferably, the decorative film does not have a convex structure with a height of 1 μm or more on the surface). 
     A shape of the above-described convex structure is not particularly limited, and examples thereof include various shapes such as a linear structure, a spiral structure, a concentric circular structure, and a wavy linear structure.

     From the viewpoint of ease of forming a cholesteric liquid crystal layer and ease of adjusting the pitch of the helical structure, the liquid crystal composition preferably includes a chiral agent (that is, an optically active compound). The chiral agent has a function of inducing a helical structure in the cholesteric liquid crystal layer. Since a twist direction or helical pitch of the helix induced by the chiral agent is different depending on the liquid crystal compound, the chiral agent may be selected according to the purpose. The chiral agent is not particularly limited, and a known compound (for example, a chiral agent for twisted nematic (TN) and super-twisted nematic (STN), compound described in “Liquid Crystal Device Handbook”, Chapter 3, Section 4-3, p. 199, Japan Society for the Promotion of Science edited by the 142nd committee, 1989), and an isosorbide or isomannide derivative can be used.

The heteroaromatic ring group may have a substituent. As the substituent, for example, a halogen atom, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, an alkoxy group, a hydroxy group, an acyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, an acyloxy group, or a cyano group is preferable, and a halogen atom, an alkyl group, an alkenyl group, an aryl group, an alkoxy group, or an acyloxy group is more preferable.

     In Formula (CH1), it is preferable that R CH1  and R CH2  are each independently a hydrogen atom. 
     The liquid crystal composition may include one chiral agent alone, or may include two or more chiral agents. A content of the chiral agent can be appropriately selected according to a desired pitch of the structure or helical structure of the specific liquid crystal compound to be used.

     —Coating and Curing of Liquid Crystal Composition— 
     In the formation of the cholesteric liquid crystal layer, for example, the liquid crystal composition is used by being applied to an object (for example, the above-described base material, and an alignment layer described later). After the liquid crystal composition is made into a solution with a solvent or made into a liquid such as a molten liquid by heating, the liquid crystal composition can be applied, for example, by an appropriate method such as a roll coating method, a gravure printing method, and a spin coating method. The liquid crystal composition can also be applied by various methods such as a wire bar coating method, an extrusion coating method, a direct gravure coating method, a reverse gravure coating method, and a die-coating method. In addition, using an inkjet device, the liquid crystal composition can be jetted from a nozzle to form a coating film (referring to a film-like liquid crystal composition formed by coating). 
     After the application of the liquid crystal composition, the cholesteric liquid crystal layer is formed by curing the liquid crystal composition. By curing the liquid crystal composition, the alignment state of molecules of the liquid crystal compound (for example, the above-described specific liquid crystal compound) is maintained and fixed. The curing of the liquid crystal composition is preferably performed by a polymerization reaction of polymerizable groups (for example, ethylenically unsaturated groups or cyclic ether groups) included in the liquid crystal compound. In a case of using the solvent as a component of the liquid crystal composition, after the application of the liquid crystal composition and before the polymerization reaction for curing, it is preferable that the coating film is dried by a known method. For example, the coating film may be dried by allowing to stand or by heating. It is sufficient that the liquid crystal compound in the liquid crystal composition is aligned after the application and drying of the liquid crystal composition. 
     —Layer Configuration of Cholesteric Liquid Crystal Layer— 
     From the viewpoint of suppressing change in reflectance after molding, the decorative film according to the embodiment of the present disclosure preferably has two or more cholesteric liquid crystal layers. In addition, compositions of the two or more cholesteric liquid crystal layers may be the same or different from each other. In a case where the decorative film according to the embodiment of the present disclosure has two or more cholesteric liquid crystal layers, it is sufficient that the decorative film according to the embodiment of the present disclosure has at least one layer formed by curing a liquid crystal composition which includes, with respect to the total solid content of the liquid crystal composition, 25% by mass or more of the cholesteric liquid crystal compound having one ethylenically unsaturated group or one cyclic ether group (that is, the specific liquid crystal compound). From the viewpoint of suppressing change in reflectance after molding, it is preferable that all the two or more cholesteric liquid crystal layers are a layer formed by curing a liquid crystal composition which includes, with respect to the total solid content of the liquid crystal composition, 25% by mass or more of the cholesteric liquid crystal compound having one ethylenically unsaturated group or one cyclic ether group. 
     In addition, for example, in a case where the decorative film according to the embodiment of the present disclosure has two cholesteric liquid crystal layers, from the viewpoint of suppressing change in reflectance after molding, it is preferable to have the cholesteric liquid crystal layer on each surface of the above-described base material. 
     &lt;&lt;Selective Reflectivity of Reflective Layer&gt;&gt; 
     The reflective layer preferably has a central wavelength of a selective reflection wavelength in a range of 300 nm or more and 1,500 nm or less. In the present disclosure, the “central wavelength of the selective reflection wavelength” refers to, in a case where the minimum value and the local minimum value of light transmittance in a target object (for example, the reflective layer) are defined as T min  (unit: %), an average value of two wavelengths showing half-value transmittance T 1/2  (unit: %) represented by the following expression. However, a first wavelength of the two wavelengths is the maximum wavelength in a wavelength range including a wavelength shorter than the wavelength indicating T min , and a second wavelength of the two wavelengths in the minimum wavelength in the wavelength range including a wavelength longer than the wavelength indicating T min . The transmittance is measured by a spectrophotometer (for example, spectrophotometer UV-2100 manufactured by Shimadzu Corporation). The central wavelength of the selective reflection wavelength may be included in a range of 380 nm or more and 780 nm or less, or in a range of more than 780 nm and 1,500 nm or less. 
     Expression for calculating half-value transmittance: 
         T   1/2 =100−(100 −T   min )/2
 
     The reflective layer preferably has a maximal reflection wavelength in a wavelength range of 380 nm to 1,500 nm. From the viewpoint of use for the decorative film, the wavelength range including the maximal reflection wavelength is preferably 380 nm to 1,200 nm, more preferably 400 nm to 1,000 nm, and particularly preferably 420 nm to 900 nm. 
     From the viewpoint of strength and durability, a thickness of the reflective layer is preferably 0.2 μm to 150 μm, more preferably 0.5 μm to 100 μm, still more preferably 1 μm to 50 μm, and particularly preferably 1 μm to 10 μm. 
     &lt;Alignment Layer&gt; 
     The decorative film according to the embodiment of the present disclosure may have an alignment layer which is in contact with the cholesteric liquid crystal layer. The alignment layer is used for aligning the molecules of the liquid crystal compound in the liquid crystal composition in a case of forming a layer including the liquid crystal compound (hereinafter, also referred to as a “liquid crystal layer”). For example, since the alignment layer is used in the case of forming the liquid crystal layer, in a decorative film which does not include the liquid crystal layer, the alignment layer may or may not be included. 
     For example, the alignment layer can be provided by a rubbing treatment of an organic compound (preferably a polymer), an oblique vapor deposition of an inorganic compound (for example, SiO 2 ), or a formation of a layer having a microgroove. Furthermore, an alignment layer in which an alignment function occurs by application of an electric field, application of a magnetic field, or light irradiation has also been known. Depending on a material of the underlayer such as the support and the liquid crystal layer, the alignment layer may not be provided and the underlayer may be subjected to a direct alignment treatment (for example, rubbing treatment) to function as an alignment layer. Polyethylene terephthalate (PET) can be mentioned as an example of such a support as the underlayer. In addition, in a case where a layer (hereinafter, referred to as an “upper layer” in this paragraph) is directly laminated on the liquid crystal layer, in some cases, the liquid crystal layer as the underlayer behaves as the alignment layer and the liquid crystal compound for forming the upper layer can be aligned. In such a case, the liquid crystal compound in the upper layer can be aligned without providing the alignment layer or performing a special alignment treatment (for example, rubbing treatment). 
     Hereinafter, as a preferred example of the alignment layer, a rubbing-treated alignment layer and a photoalignment layer will be described. 
     &lt;&lt;Rubbing-Treated alignment Layer&gt;&gt; 
     The rubbing-treated alignment layer is an alignment layer to which aligning properties are imparted by a rubbing treatment. Examples of a polymer which can be used in the rubbing-treated alignment layer include a methacrylate-based copolymer, a styrene-based copolymer, polyolefin, polyvinyl alcohol and modified polyvinyl alcohol, poly(N-methylol acrylamide), polyester, polyimide, a vinyl acetate copolymer, carboxymethyl cellulose, and polycarbonate, which are described in paragraph 0022 of JP1996-338913A (JP-H8-338913A). A silane coupling agent can be used as the polymer. As the polymer which can be used in the rubbing-treated alignment layer, a water-soluble polymer (for example, poly(N-methylol acrylamide), carboxymethyl cellulose, gelatin, polyvinyl alcohol, and modified polyvinyl alcohol) is preferable, gelatin, polyvinyl alcohol, or modified polyvinyl alcohol is more preferable, and polyvinyl alcohol or modified polyvinyl alcohol is particularly preferable. 
     In a method of aligning the liquid crystal compound using the rubbing-treated alignment layer, for example, the molecules of the liquid crystal compound are aligned by coating a rubbing-treated surface of the rubbing-treated alignment layer with a composition for forming a cholesteric liquid crystal layer (one aspect of the liquid crystal composition). Thereafter, as necessary, by reacting the polymer included in the alignment layer with a polyfunctional monomer included in the cholesteric liquid crystal layer, or by crosslinking polymer included in the alignment layer using a crosslinking agent, the cholesteric liquid crystal layer can be formed. A film thickness of the alignment layer is preferably in a range of 0.1 μm to 10 μm. 
     —Rubbing Treatment— 
     The surface of the alignment layer, the support, or other layers, to be coated with the composition for forming a cholesteric liquid crystal layer, may be subjected to a rubbing treatment as necessary. The rubbing treatment can be generally performed by rubbing a surface of a film containing a polymer as a main component with paper or cloth in a certain direction. The general method of the rubbing treatment is described in, for example, “Handbook of Liquid crystals” (published by Maruzen, Oct. 30, 2000). 
     As a method of changing a rubbing density, the method described in “Handbook of Liquid crystals” (published by Maruzen) can be used. The rubbing density (L) is quantified by Expression (A). 
         L=Nl (1 +2π rn/ 60 v )   Expression (A)
 
     In Expression (A), N is the number of times of rubbing, π is the pi, l is a contact length of a rubbing roller, r is a radius of the roller, n is a rotation speed (revolutions per minute: rpm) of the roller, and v is a stage moving speed (speed per second). 
     In order to increase the rubbing density, it is sufficient that the number of times of rubbing is increased, the contact length of the rubbing roller is increased, the radius of the roller is increased, the rotation speed of the roller is increased, or the stage moving speed is decreased. On the other hand, in order to decrease the rubbing density, it is sufficient that the reverse is carried out. In addition, with regard to conditions for the rubbing treatment, the description in JP4052558B can be referred to. 
     &lt;&lt;Photoalignment Layer&gt;&gt;

Among these, it is preferable to have a sheet in which a convex shape is formed by a resin base material and a cured product of a curable composition, provided on at least one surface of the resin base material. 
     (Resin Base Material) 
     Examples of the resin base material include a sheet or film of an acrylic resin, a polyester resin, a polycarbonate resin, and the like. 
     Examples of the acrylic resin include polymethyl methacrylate. 
     Examples of the polyester resin include polyethylene terephthalate (PET) and polyethylene naphthalate (PEN). 
     A thickness of the resin base material is not particularly limited, and is preferably in a range of 50 μm or more and 300 μm or less and more preferably in a range of 50 μm or more and 200 μm or less in a case of uniformly molding (forming) at a high temperature. Within the above-described range, the resin base material is less likely to be torn, cracks are less likely to occur during handling (for example, during transportation) in the molding process, and cracks are less likely to occur during three-dimensional molding. 
     As the resin base material, a commercially available product on the market may be used. For example, an acrylic resin film (ACRYPLEN HBS010P (PMMA film), thickness: 125 μm) manufactured by Mitsubishi Chemical Corporation, a polyethylene terephthalate resin film (LUMIRROR S10, thickness: 100 μm) manufactured by Toray Industries, Inc., and a polycarbonate resin film (IUPILON H-3000, thickness: 125 μm) manufactured by Teijin Chemicals Ltd.

     Specifically, for example, a mold processed into a desired convex shape may be prepared, a curable composition may be poured into the mold, the curable composition may be dried as necessary to cure the curable composition. As a result, a molded product molded into a desired shape is stably obtained. 
     Next, a radical is generated by irradiation the curable composition with an active energy ray, and the curable composition cures as the polymerization reaction of the polymerizable compound proceeds. As a result, a convex shape which is a cured product of the curable composition is formed. 
     In molding the convex shape, the curable composition may be cured after the resin base material is brought into contact with the curable composition in advance before the curable composition is cured. By curing the resin base material in contact with the curable composition, it is expected that adhesiveness due to curing shrinkage is further improved, and in addition to the adhesion effect derived from the composition, adhesiveness to the resin base material can be improved more effectively. 
     The mold for forming the convex structure can be produced by a known method such as cutting and etching. It is preferable to use a mold produced by an etching process because it is easy to obtain lustrousness in a case where the decoration product is held in a hand and viewed obliquely. From the viewpoint of lustrousness in a case of being viewed from the front, it is preferable to use a mold produced by cutting.

The surface having a convex structure functions as a mold for imparting the convex structure to the reflective layer. By bringing the reflective layer into contact with the surface having an uneven structure and pressurizing the reflective layer, the reflective layer is deformed along the surface having the convex structure. As a result, the convex structure is imparted to the reflective layer. 
     The layer configuration of the decorative film may be determined according to the layer configuration of the desired decorative molded article. For example, by using a decorative film having a base material, a reflective layer, and a resin layer between the base material and the reflective layer, a decorative molded article including the base material, the resin layer, and the reflective layer in this order is obtained. 
     The surface having a convex structure is defined by an outer surface of various articles. The surface having a convex structure may be, for example, a surface of a mold or a surface of an article other than the mold. 
     In the process of bringing the reflective layer into contact with the surface having a convex structure, the reflective layer may be brought close to the surface having a convex structure, or the surface having a convex structure may be brought close to the reflective layer. The reflective layer may be brought into contact with the surface having a convex structure through another layer (for example, an alignment layer). 
     The pressure applied to the reflective layer is preferably 0.1 MPa or more, more preferably 0.3 MPa or more, and particularly preferably 0.5 MPa or more. The upper limit of the pressure applied to the reflective layer is not limited. The upper limit of the pressure applied to the reflective layer may be determined, for example, in accordance with workability of the reflective layer and the thickness of the decorative film. The pressure applied to the reflective layer is preferably 10 MPa or less, more preferably 3 MPa or less, and particularly preferably 1 MPa or less. 
     A method of applying the pressure to the reflective layer is not limited, and a known method can be used. Examples of the method of applying the pressure include a method using compressed air and a method using a pressing machine. 
     In the method for manufacturing the decorative molded article, as the article having the surface having a convex structure, for example, a transparent body having the surface having a convex structure (that is, a convex surface) may be used. For example, in a method for manufacturing the decorative molded article according to a certain embodiment, it is preferable to include a step of preparing a decorative film having at least a base material and a reflective layer which has a central wavelength of a selective reflection wavelength in a range of 300 nm or more and 1,500 nm or less; and a step of bringing the reflective layer into contact with the surface having a convex structure by superimposing the transparent body having the surface having a convex structure and the decorative film, and then applying a pressure of 0.01 Mpa or more to the reflective layer to impart a convex structure to the reflective layer. After imparting the convex structure to the reflective layer, the transparent body may or may not be removed. In a case where the transparent body is not removed, the transparent body is disposed, for example, as an outer layer of the decorative molded article.

     &lt;Production of Laminate  1 - 3 &gt; 
     The laminate  1 - 1  and the laminate  1 - 2  were bonded together by a laminator such that the above-described resin layer  1  and the above-described cholesteric liquid crystal layer  1  were in contact with each other. By peeling off the PET film (that is, the support  1 A) on the side of the laminate  1 - 1 , a laminate  1 - 3  in which support  1 B/resin layer  1 /cholesteric liquid crystal layer  1 /alignment layer  1  were laminated in this order was obtained. 
     &lt;Preparation of Black Pigment Dispersion Liquid&gt; 
     Carbon black, a dispersant, a polymer, and a solvent were mixed so as to be a black pigment dispersion liquid having a composition of the below, and a black pigment dispersion liquid was obtained by using a three-roll mill and a beads mill. An average particle diameter of the carbon black, measured using Microtrac FRA (Honeywell Japan Ltd.), was 163 nm.

     &lt;Production of Laminate  1 &gt; 
     The coating liquid  1  for forming a colored layer was applied onto the support  1 B of the laminate  1 - 3  described above using a wire bar coater, and dried at 100° C. for 10 minutes. The surface of the colored layer of the formed laminate was entirely exposed with an exposure amount of 500 mJ/cm 2  (i rays) to form a colored layer  1  (black colored layer) having a layer thickness of 4 μm, thereby forming a laminate  1 . The laminate  1  includes the colored layer  1 , the support  1 B, the resin layer  1 , the cholesteric liquid crystal layer (reflective layer)  1 , and the alignment layer  1  in this order. 
     &lt;Molding&gt; 
     The surface of the alignment layer  1  of the laminate  1  was subjected to a corona treatment using a table corona treatment device (TEC-8XA, manufactured by KASUGA DENKI, INC., setting output: 70 W, operation speed: lm/min, number of times: 5 reciprocations), and using a transparent body having a convex pattern (thickness: 2 mm, width: 50 mm, length: 50 mm) as a mold, the surface of the alignment layer  1  of the laminate  1  was brought into contact with the convex surface of the transparent body, and subjected to a compressed air molding (TOM molding) to obtain a molded article  1  (that is, a decorative molded article). The convex pattern had the shape shown in Example 1 in Table 1. A TOM molding machine NGF-0510-R (manufactured by Fu-se Vacuum Forming) was used for the compressed air molding, and the molding temperature was set to 120° C. and the stretching ratio was set to 30% at the highest portion. The pressure in the compressed air molding was 0.3 MPa. 
     &lt;Measurement of Average Φ AVE  of Positive Tilt Angles&gt; 
     A microtome (for example, RX-860 manufactured by YAMATO KOHKI INDUSTRIAL CO., LTD.) was used to cut the decorative film on an arbitrary plane in a direction (360° existing as a direction) perpendicular to the plane direction of the decorative film. The cutting direction could be predicted to some extent by observing the surface of the decorative film with a microscope (BX53M manufactured by Olympus Corporation). A cross-sectional shape was measured by observing the cut cross section with a scanning electron microscope (SU3800 manufactured by Hitachi High-Tech Corporation), and Φ AVE  was calculated. 
     &lt;Performance Evaluation&gt; 
     —hange in Tint for Each Viewing Direction (Evaluation of Change in Brightness in Case of Being Horizontally Rotated on Table)— 
     Using an ultraviolet-visible-near infrared spectrophotometer (manufactured by JASCO Corporation, V-750) and an automatic absolute reflectance measurement unit (manufactured by JASCO Corporation, ARMV-919), reflectance in a wavelength range of 380 nm to 780 nm was measured. The reflectance indicates the maximum value of reflection spectrum in a case where a horizontal axis represents the wavelength and a vertical axis represents the reflectance. Reflectance in a case where the molded article was set on a sample holder so that the first direction was an incident surface was defined as a highlight reflectance (R H ), and reflectance in a case where the same region was set so that the second direction was an incident surface was defined as a shade reflectance (R S ). A ratio (R H /R S ) of the above-described reflectance was measured. However, the incidence angle and the light-receiving angle were set to be angles at which the ratio (R H /R S ) of the above-described reflectance was maximized within a range of the incidence angle of 0° to −45° and the light-receiving angle of −90° to 90°. The angle indicates an absolute angle with the perpendicular line to the base material plane as 0°. Change in tint for each viewing direction was evaluated according to the following standard. As an evaluation result, C is preferable, B is more preferable, and A is particularly preferable.

     As shown in Tables 1 and 2, the decorative films of Examples 1 to 11, which are the decorative film according to the embodiment of the present disclosure, were decorative films rich in tint change depending on the viewing direction, as compared to the decorative films of Comparative Examples 1 to 4. 
     Example 12 
     Display Decorative Film 
     A molded article A- 1  was produced in the same manner as in Example 1, except that, in Example 1, the coating liquid  1  for forming a cholesteric liquid crystal layer prepared above was applied onto the rubbing-treated surface of the alignment layer  1  with a wire bar coater, and dried at 85° C. for 120 seconds. Thereafter, as shown in  FIG.  9   , through a mask pattern, light from a metal halide lamp (MAL625NAL manufactured by GS Yuasa International Ltd.) with an exposure amount of 30 mJ/cm 2  was irradiated to the liquid crystal layer portion to perform an isomerization treatment of a reflected wavelength, thereby forming a black layer. After the above-described process, the liquid crystal layer exhibited a reflection pattern of a gradation color of blue to red. 
     Further, a retardation layer of a ¼ wavelength plate was transferred to the cholesteric liquid crystal layer on a surface opposite to the surface on which the liquid crystal layer of the base material was formed by the method described in paragraphs 0170 and 0171 of JP2017-215558A, thereby forming a molded article A- 2 . 
     Further, on the side of the transparent body having the linear convex pattern (A), the retardation layer of the ¼ wavelength plate was transferred to the transparent body having the linear convex pattern (A) (on the smooth surface side without the convex pattern) and laminated by the method described in paragraphs 0170 and 0171 of JP2017-215558A, thereby forming a molded article A- 3 . 
     In this case, each ¼ wavelength plate was disposed such that transmittance was maximized in a case where linearly polarized light was transmitted through the liquid crystal layer. 
     Further, an acrylic pressure sensitive adhesive (SK-Dyne SG-50Y, manufactured by Soken Chemical &amp; Engineering Co., Ltd.) was applied onto the retardation layer of the ¼ wavelength plate, which was laminated on the side of the transparent body having the linear convex pattern (A), with a comma coater, and dried at 120° C. for 2 minutes, thereby forming a resin layer A- 4  (adhesive layer) having a layer thickness of 20 μm. 
     Further, a liquid crystal axisymmetric polarization converter (RADPOL4, manufactured by ARCoptix) was rubbed on the resin layer A-4 with a silicone rubber roller at room temperature to form a molded article A- 5 . 
     The molded article A- 5  was installed on a display unit of ipad-pro (manufactured by Apple Inc., liquid crystal display) so that the liquid crystal axisymmetric polarization converter came to the outermost surface. In this case, the molded article was disposed in a direction in which transmittance of linearly polarized light output from the display was maximized. In a case where display of the display was turned on, when light transmitted through the liquid crystal axisymmetric converter was set to be the linearly polarized light, the displayed image on the display was clearly visible, and the pattern of the decorative film was hardly visible. On the other hand, in a case where display of the display was turned off, when the liquid crystal axisymmetric converter was set to transmit all light, the reflected color of the decorative film (gradation of blue to red) was clearly visible, and a pattern with high lustrousness and rich reflected color change depending on the viewing angle was also visible.
