  In a multi-layered decorative film having a temperature indicating paint or a fluorescent paint as one of the pattern layers, by providing a light shielding layer on the temperature indicating paint or the fluorescent paint, it is possible to prevent light deterioration of the paint. However, covering the decorative paint with a light-shielding layer also shields the decorative paint from the viewer's vision, and adding a decorative property by using the light-shielding layer as a pattern layer. Even if it is done, it is inevitable that the original decorating property as a decorative film is lowered.

  It is an object of the present invention to provide a multi-layered decorative film that can eliminate the above disadvantages to some extent. More specifically, in a multi-layered decorative film in which a pattern layer made of a light shielding material is formed on a pattern layer made of a photodegradable paint such as a temperature indicating paint or a fluorescent paint, the photodegradable paint has An object of the present invention is to provide a multi-layered decorative film in which designability is not reduced by allowing a person who looks at designability to visually recognize.

  The multi-layered decorative film according to the present invention has a multi-layered structure in which a first clear layer, a first pattern layer, a second pattern layer, an adhesive layer, a second clear layer, and a mirror-deposited metal deposition layer are stacked in this order from the surface. The first pattern layer is a pattern layer made of a light shielding material, the second pattern layer is a pattern layer made of a photodegradable paint, the adhesive layer and the first and second layers. The clear layer is a light-transmitting layer, at least the second pattern layer is disposed in the adhesive layer, and a predetermined interval is provided between the second pattern layer and the metal deposition layer. It is characterized by that.

  In the above-mentioned multi-layered decorative film, the second pattern layer made of the photodegradable paint is covered with the first pattern layer made of the light shielding material, and the photodegradable paint forming the second pattern layer is the surface. You will not receive direct light from. Thereby, it is suppressed that a coating material photodegrades. On the other hand, the pattern of the second pattern layer is reflected on the mirror-deposited metal deposition layer, but at least the thickness of the second clear layer that is light transmissive between the second pattern layer and the mirror-deposition metal deposition layer. The person who sees the pattern at an angle inclined from the vertical direction can visually recognize a part of the second pattern layer reflected on the metal deposition layer from the surface side. That is, the viewer can visually recognize the pattern in a state where the first pattern layer is superimposed on the second pattern layer in a state of being displaced from the surface side. Therefore, high designability is ensured as a multi-layered decorative film.

  In the multi-layered decorative film according to the present invention, there is no particular limitation on the photodegradable paint forming the second pattern layer, and any paint used in conventional decorative films can be used. An example is a temperature indicating paint or a fluorescent paint. The photodegradable coating material forming the reversible temperature-sensitive multicolor discoloration layer described in Patent Document 1 may be used. In addition, the fluorescent paint emits visible light from the fluorescent material, but the pattern of the emitted light is also reflected on the metal vapor deposition layer, and the viewer can also see the reflected pattern from the surface side. When the second pattern layer is formed of a fluorescent paint, a multi-layered decorative film having higher design properties can be obtained.

  In the multi-layered decorative film according to the present invention, the light shielding material constituting the first pattern layer is not particularly limited, and any material can be used on condition that a desired light shielding property is obtained.

  In the multi-layered decorative film according to the present invention, the size of the predetermined interval provided between the second pattern layer and the metal vapor deposition layer is not particularly limited and is arbitrary. When viewed from the same inclination angle, the larger the interval, the greater the misalignment between the first pattern layer and the second pattern layer reflected in the metal vapor deposition layer, so that a higher design can be given to the viewer. it can. However, if the interval is too large, the sharpness of the pattern reflected in the metal vapor deposition layer may be lacking, and the design may be deteriorated. Preferably, the interval is about 0.5 to 7 mm.

  According to the present invention, in a decorative film having a pattern layer made of a photodegradable paint, the photodegradation of the photodegradable paint can be suppressed, and at the same time, a person who sees the design of the photodegradable paint can be visually recognized. By making it, it is possible to obtain a multi-layered decorative film that does not deteriorate the design.

Hereinafter, the present invention will be described based on embodiments.
[First Embodiment]
FIG. 1 shows a first embodiment A1 of a multi-layered decorative film according to the present invention. As shown in the cross-sectional view of FIG. 1 (a), the decorative film A1 has a first clear layer 1, a first pattern layer 2, a second pattern layer 3, an adhesive layer 4, a second clear layer 5, from the surface. A mirror-deposited metal vapor deposition layer 6 is laminated in this order. Although not shown, a base material sheet made of an appropriate material may be disposed under the mirror-deposited metal deposition layer 6.

  The first clear layer 1 is made of a light transmissive and preferably transparent material. Examples of light transmissive materials include acrylic resins and polyester resins. The first clear layer 1 may be a coating film or a film. The thickness is preferably about 0.2 to 30 μm. In addition, the 1st clear layer 1 is for protecting a pattern layer, and is generally used in the conventional multi-layered decorative film.

  The first pattern layer 2 is a pattern layer made of a light shielding material. Examples of the light shielding material include acrylic ink and urethane ink. The first pattern layer 2 is preferably a coating layer and contains appropriate dyes and pigments for decoration. The metallic luster pigment layer is preferable in terms of design. The thickness is preferably about 1 to 40 μm.

  The second pattern layer 3 is a pattern layer made of a photodegradable paint, and in the example shown in FIG. 1, a temperature indicating paint is used. Specific examples of the temperature indicating paint include those manufactured by Matsui Dye Chemical Co., Ltd., Kuromi Color (registered trademark), Thermolock (registered trademark), and the like. Again, suitable dyes and pigments are included for decoration. The first pattern layer 2 is superimposed on the second pattern layer 3, and both have the same area and shape, or the first pattern layer 2 is slightly larger than the second pattern layer 3. . The thickness is preferably about 1 to 40 μm. The first pattern layer 2 and the second pattern layer 3 are not formed on the entire surface of the multi-layered decorative film A1, but are formed with a large number of gaps in the surface direction. In addition, examples of the photodegradable paint include fluorescent paints and luminescent paints. An example using a fluorescent paint will be described as a second embodiment based on FIG.

  The adhesive layer 4 is a layer for adhering the first clear layer 1 and the second clear layer 5 described later, and is made of a light transmissive and preferably transparent material. Specific examples of the material include adhesives such as acrylic resins and polyester resins. Of the first pattern layer 2 and the second pattern layer 3 described above, at least the second pattern layer 3 is disposed in the adhesive layer 4. When a film is used as the first clear layer 1, both the first pattern layer 2 and the second pattern layer 3 are located in the adhesive layer 4 for the convenience of manufacturing. The thickness of the adhesive layer 4 is preferably about 1 to 100 μm.

  The second clear layer 5 is made of a light transmissive and preferably transparent material. Examples of the material of the second clear layer 5 include polyester, acrylic, polycarbonate, and the like. The second clear layer 5 may be a coating film or a film. The second clear layer 5 is formed together with the adhesive layer 4 in order to provide a predetermined interval between the metal vapor deposition layer 6 and the second pattern layer, which will be described later. Depending on whether or not, it is appropriate thickness. Preferably, it is about 0.5-7 mm.

  The mirror-deposited metal deposition layer 6 is provided to reflect the second pattern layer 3 and is formed on the back surface of the second clear layer 5 by a conventionally known method such as vacuum deposition or sputtering. The Examples of the material of the metal vapor deposition layer 6 include chromium, nickel, aluminum, and titanium. The thickness may be about 0.02 to 0.5 μm. As described above, when a base sheet (not shown) is used, a mirror-like metal vapor deposition layer 6 may be formed on the surface of the base sheet.

  Next, an example of the manufacturing procedure of the multi-layered decorative film A1 will be described. In the production, first, a second clear layer 5 having a required thickness in which a mirror-like metal vapor deposition layer 6 is formed on the back surface by a conventionally known method such as vacuum vapor deposition or sputtering is prepared. An adhesive layer 4 is applied and formed on the surface of the second clear layer 5 opposite to the metal vapor-deposited layer 6 to a required thickness, and a second pattern layer 3 and a first pattern layer 2 having the required thickness are formed thereon by printing means or the like. Are formed in this order. Next, the first clear layer 1 is applied and formed to a required thickness from above, or a film having a required thickness is laminated.

  When the first clear layer 1 is a film, both the second pattern layer 3 and the first pattern layer 2 are embedded in the adhesive layer 4, and when formed by a coating film, at least the second The first clear layer 1 is formed so that the pattern layer 3 is embedded in the adhesive layer 4. Although the description is omitted, the decorative film A1 can also be manufactured by a procedure reverse to the above. In any case, by performing a required drying process, a multi-layered decorative film A1 according to the present invention is obtained.

  FIG.1 (b) has expanded and shown the part of the pattern layer in Fig.1 (a). As shown in the drawing, the second pattern layer 3 made of a photodegradable paint is covered on the surface side by the first pattern layer 2 made of a light shielding material, and the light from the first clear layer 1 side is directly second. The pattern layer 3 is not irradiated. For this reason, the rate at which the second pattern layer 3 undergoes photodegradation is greatly reduced. On the other hand, an interval t formed by the thickness of the adhesive layer 4 positioned below the second pattern layer 3 and the thickness of the second clear layer 5 is formed between the second pattern layer 3 and the metal vapor deposition layer 6. Thus, a mirror image 7 of the second pattern layer 3 is projected on the metal deposition layer 6.

  Due to the existence of the interval t, when viewed from a tilted direction (for example, the direction of the arrow x in FIG. 1B) instead of a direction perpendicular to the mirror image plane, the viewer sees 7a in FIG. As shown, a part of the mirror image 7 of the second pattern layer 3 can be visually recognized. That is, since the viewer can see all of the first pattern layer 2 and the part 7a of the mirror image 7 of the second pattern layer 3 at the same time, the decoration property of the multi-layered decorative film A1 is sufficient. Can be recognized, and high designability is ensured as the decorative film A1.

[Second Embodiment]
FIG. 2 shows a second embodiment A2 of the multi-layered decorative film according to the present invention. The decorative film A2 of the second form is different from the decorative film A1 of the first form shown in FIG. 1 only in that the second pattern layer 3 is formed of a fluorescent paint. Other configurations and materials that can be used may be the same as those of the decorative film A1 of the first embodiment, and the same reference numerals are given and description thereof is omitted.

  The fluorescent paint forming the second pattern layer 3 has a state of emitting fluorescence and a state of not emitting fluorescence. In a state where light is not emitted, the appearance of the second pattern layer 3 is the same as the decorative film A1 of the first form, as shown in FIGS. 2 (b1) and (c1). In the state where the fluorescent light is emitted, the fluorescent light leaks into the adhesive layer 4 around the second pattern layer 3 as shown in FIG. Then, as shown in FIG. 2 (c <b> 2), the leaked light 8 is also displayed as an image 9 of the metal deposition layer 6.

  Therefore, a viewer can see both the light 8 leaking into the adhesive layer 4 around the second pattern layer 3 and the image 9 of the metal deposition layer 6. As the decorative film A2, even higher designability is ensured.

Hereinafter, the decorative film of this invention is demonstrated by an Example and a comparative example.
[Example]
A metal vapor deposition layer 6 having a thickness of 0.1 μm was formed on one surface of a colorless and transparent polyester resin film having a thickness of 1 mm, which was the second clear layer 5, by vacuum vapor deposition. Next, the adhesive layer 4 was formed by applying a polyester resin adhesive with a thickness of 15 μm to the surface of the second clear layer 5 opposite to the metal deposition layer 6.

  A plurality of second pattern layers 3 are formed on the adhesive layer 4 using a photodegradable paint (Matsui Dye Chemical Co., Ltd., Kuromi Color (registered trademark), Thermolock (registered trademark)). The first pattern layer 2 made of acrylic resin, which is a light shielding material, was formed to a thickness of 1 μm by gravure printing so as to overlap with the pattern 3.

  Then, a colorless and transparent polyester resin film having a thickness of 20 μm was laminated as the first clear layer 1 so as to cover the entire surface of the second clear layer 5 to obtain a laminate. As a result, a gap t having a thickness of approximately 1,015 μm was formed between the back surface of the second pattern layer 3 and the metal deposition layer 6. The laminated body was dried to obtain a multi-layered decorative film.

[Comparative example]
As shown in FIG. 3, the metal vapor deposition layer 6 was formed on the surface of the base material sheet | seat 10 which is acrylic resin similarly to the Example. On the formed metal vapor deposition layer 6, the same polyester resin as the Example was apply | coated by 2 micrometers in thickness, and the contact bonding layer 4a was formed. On the adhesive layer 4a, the second pattern layer 3 and the first pattern layer 2 are formed in the same manner as in the example, and the entire surface of the base sheet 10 is covered from the second pattern layer 3 and the first pattern layer 2, and the same as in the example. The film was laminated as the first clear layer 1. Due to the relationship between the thickness of the adhesive layer 4a and the thickness of the second pattern layer 3 and the first pattern layer 2, the second pattern layer 3 and the first pattern layer 2 are all in the adhesive layer 4a. No gap was substantially formed between the lower surface of the two patterned layers 3 and the metal vapor-deposited layer 6. By drying the formed laminate, a multi-layered decorative film as a comparative example was obtained.

[Observation]
The example product and the comparative example product were placed in the same environment, and the pattern was seen from a direction inclined 45 degrees from the vertical direction of the decorative film. In the example product, the entire first pattern layer 2 and a part of the second pattern layer 3 under the first pattern layer 2 were visible. However, in the comparative product, the entire first pattern layer 2 was visually recognized, but the second pattern layer 3 was not visually recognized. From this, it was found that the multi-layered decorative film according to the present invention can ensure high designability as a decorative film.
