Next, on the surface 10a of the film (concealment layer) 10 on which the pattern printing layer 7 is formed, that is, on the surface on which the pattern printing layer 7 is formed, a transparent vinyl chloride resin having a thickness of 80 μm as the base film 2 is formed. A film is laminated and adhered, and the base film 2 is embossed with a concavo-convex pattern of a perforated oak material similar to that of the fifth embodiment. Then, the wiping ink 5 similar to that in the fifth embodiment is filled in the concave portion 3 having the uneven pattern, and the colored coating layer 6 is formed only on the convex portion 4 having the uneven pattern with the same coating liquid as in the fifth embodiment. Let it form.

According to the decorative film 61 of this embodiment,
As in the case of the fifth embodiment described above, since the matte ink 5 having a glossiness of about 8 minutes was filled in the concave portion 3 having the uneven pattern, a three-dimensional effect was obtained by contrasting with the gloss of the coat layer 6 and coloring. In addition, since the concealing layer 10 made of the colored film is formed on the back surface 2b of the base film 2, the decorative film 61 in which the grain pattern is expressed can be obtained.

VII. Seventh Embodiment Next, a seventh embodiment will be described. FIG. 7 is a sectional view of a decorative film according to the seventh embodiment of the present invention. As shown in FIG. 7, the decorative film 71 of this embodiment uses a transparent vinyl chloride resin film having a thickness of 150 μ as the base film 2, and the surface 2 a of the base film 2 is covered with the fifth film.
The conduit pattern of oak grain similar to that in the example was embossed to form a concavo-convex pattern. Only the convex portions 4 of the concavo-convex pattern had 73 clear coating liquid, 5 matte coating liquid, 10 black coating liquid, and red. The coating layer 6 is formed by using a colored transparent coating solution of Kokuto glossy with a coating solution of 1, a yellow coating solution of 2, and a curing agent of 9 in the ratio of a dark brown urethane resin as a binder. At this stage, the concave and convex portions 3 are not colored. When a veneer plywood serving as the concealing layer 10 is attached to the back surface 2b of the base film 2 in this state, the color of the veneer plywood appears in the embossed concave portion 3 and a plywood that seals the conduit is completed. , In the concave and convex portion 3 of this film, 62 for medium, 22 for white, 1 for blue, 1.5 for red, 1.5 for yellow,
When the wiping ink 5 having a curing agent of a ratio of 9 and having a color close to that of the powder is applied and filled, the coating is performed as in the first to sixth embodiments described above. Since the difference in the unevenness between the surface of the layer 6 and the ink 5 in the concave portion 3 is small, a realistic decorative film 71 having a closed conduit is completed.

According to the decorative film 71 of this embodiment,
The colored coating liquid of the coating layer 6 of the convex portion 4 does not enter into the concave portion 3 of the concave-convex pattern which becomes a conduit pattern as in each of the above-described embodiments. Therefore, after the coating layer 6 is formed, the concave portion formed by wiping is formed. The ink 5 in 3 can be filled, and since the roughness of the convex portions 4 of the base film 2 is smoothed by forming the coat layer 6, the wiping process can be easily performed. Then, this decorative film 71 also has a three-dimensional effect and a deep decorative film can be obtained as in each of the above-described embodiments.

In each of the above-mentioned embodiments, the base film 2 was formed with an uneven pattern by embossing, and then the coating layer 6 was wiped only on the convex portions 4 of the uneven pattern and only the concave portion 3 was wiped. The ink 5 is filled by means of, but the order of the steps of forming the coat layer 6 and filling the ink 5 may be performed first. However, the wiping treatment after forming the coat layer 6 is performed after the coating liquid of the coat layer 6 is completely cured.

As described above, in the decorative film according to the present invention, the coating layer is formed on the convex portion of the embossed pattern formed on the surface of the base film. It has the effect of improving scratch resistance. In addition, this decorative film has a structure in which the coating layer is formed only on the convex portions of the uneven pattern due to embossing, and this coating layer is not formed inside the concave portions, so the amount of coating liquid used during coating is greatly reduced. In addition, it is possible to express the difference in gloss between the concave portion and the convex portion, which has the effect of visually giving a three-dimensional effect and producing a deep pattern. Furthermore, when this coat layer is formed as a colored coat layer, it is possible to obtain a decorative film with a realistic appearance that is similar to, for example, a wood grain paint finish in combination with the uneven pattern due to embossing. Also, if this decorative film is attached to a transparent substrate such as a glass plate that transmits light, a plate glass having an etching glass tone pattern can be easily obtained, and light such as a mirror is reflected. If it is attached to the base material, the light that passes through the film and is reflected, and the diffusion of light at the embossed part becomes complicated, and the uneven pattern due to embossing is emphasized.
This has the effect of producing a complicated pattern.
