2. Description of the Related Art Generally, a design is provided by giving a print pattern on the surface of a base material by a method such as gravure printing or offset printing, but there is no depth in color and a three-dimensional effect is obtained. There is a defect that is lacking. In order to improve this drawback, as shown in FIG. 2, a decorative sheet 4 ′ having a laminated structure in which a surface layer 2 ′ made of a transparent resin is provided on a printed pattern 1 such as a printing paper has been proposed. However, in this decorative sheet 4 ′, the transparent resin layer 2 ′ is thin and has no sense of depth, and even if the transparent resin layer 2 ′ is thick, it seems that the printed pattern 1 exists at the same distance from the surface. There is no sense of perspective,
There was a drawback that could not express the depth. There is a method to evenly disperse the fine mica pigment coated with titanium dioxide in the transparent resin layer 2 ', but this does not mean that a pattern is formed by mica, but a pearly tone is obtained due to the color relationship between reflected light and transparent light. It is added for the purpose of giving the luster, and it does not give a sense of perspective and cannot express the depth. In addition, fine mica is generally used for producing a pearly texture, and mica having a large particle size is usually colored and used for the purpose of expressing a pattern by the mica itself.

Means for Solving the Problems In view of the above points, the present inventor has conducted extensive studies, and as a result, a transparent resin composed of a transparent resin prepared by blending transparent scale-like particles such as mica having a large particle diameter with a transparent resin. The present invention has been completed by finding that a depth (depth) feeling can be provided by providing a resin layer on a printed pattern.

The invention of claim 1 of the present invention is a decorative sheet having a three-dimensional effect, wherein a transparent resin layer containing scale-like particles is formed on a printed pattern. In the invention of claim 2 of the present invention, after forming a printed pattern on the release agent layer of the release sheet and forming a transparent resin layer containing scale-like particles on the printed pattern,
A method for producing a decorative sheet having a three-dimensional effect, which comprises removing the release sheet.

A cross section of the decorative sheet 4 of the present invention is shown in FIG. A decorative sheet 4 having a laminated structure in which a transparent resin layer 2 made of a transparent resin containing transparent scale-like particles 3 such as mica having a large particle size is provided on a printed pattern 1 such as a printing paper. The addition of transparent scale-like particles 3 to the decorative sheet 4 makes the distance from the surface to the printed pattern 1 look different depending on the location, which creates a sense of perspective and gives a very deep appearance. (Depth) will be expressed. In addition, in the transparent resin layer 2, the scale-like substance 3
Partly reflects the light 5, which has the effect of giving the material a crystal-like sparkle.

The thickness of the transparent resin layer is preferably 200 μm or more for effectively expressing the depth, and 2000 μm or less for expressing a natural feeling. More preferably, it is 500 to 1000 μm. A transparent resin layer containing no scale-like particles may be further provided on the surface of the transparent resin layer for the purpose of ensuring glossiness, weather resistance and surface hardness.

The transparent scale used in the present invention is not particularly limited as long as it is scale-like, and specific examples thereof include mica and glass flakes. The maximum size of the scale is 0.3 to 8.0 m.
m is preferable. More preferably, it should be 2 to 4 mm. If the diameter is 0.3 mm or less, it is too small to express the perspective and the depth cannot be obtained, and if it is 8.0 mm or more, the fluidity of the transparent paste-like material forming the transparent resin layer is low. And the transparent resin layer becomes non-uniform in thickness, resulting in extremely poor moldability. The thickness of the scaly particles exhibiting the above characteristics is preferably 0.15 mm or less. The amount of scaly particles added to the transparent resin is 0.5 by weight percent.
It is preferably -15%. More preferably 3 to
7% is recommended.

The release sheet used in the present invention is not particularly limited, and examples thereof include known ones such as biaxially oriented polyester film or sheet, nylon or polyolefin film or sheet provided with a silicone release agent. be able to. The print pattern formed on the release agent layer of the release sheet used in the present invention is not particularly limited, for example, a print pattern provided by a method such as gravure printing or offset printing, the printing paper itself, Alternatively, a printed pattern formed by painting may be used, and the thickness, the type of the pattern, etc. may be arbitrary. It is preferable that the printed pattern has light and shade, because it produces an effect of giving an illusion of a sense of distance, resulting in a decorative sheet with more depth and change.

The base material which can be used as a decorative material by laminating the decorative sheet of the present invention may be wood, FRP, gypsum board, metal, ceramics, or a combination thereof, and is not particularly limited. Absent.

The transparent resin used in the present invention may be a thermoplastic resin or a thermosetting resin as long as it has transparency. Specifically, for example, a transparent material such as vinyl chloride resin, unsaturated polyester, acrylic resin, etc. Examples thereof include, but are not limited to, resins having The form when using these resins is
It may be a solution, emulsion, sol, or the like. Preferably, a resin having an optical density in the visible range of 0.8 or less when the resin is molded into a transparent resin layer having a thickness of 200 μm is preferable.

[0012]

[Function] A transparent paste material such as vinyl chloride sol to which scaly particles such as mica having a large particle diameter is added onto the printed pattern formed on the release sheet, is heated, and is then gelled. The decorative sheet of the present invention made by removing the release sheet, the transparent resin layer containing the scale-like particles is provided on the printed pattern, so that the distance from the surface to the pattern looks different depending on the location. As a result, the appearance of the pattern of the background is changed and a sense of perspective is created, and the flexible decorative sheet is capable of expressing a texture with a depth (depth) and a very three-dimensional effect. Further, since the scaly particles partially reflect light in the transparent resin layer, it is possible to give the material a crystal-like glittering feeling.

EXAMPLES The present invention will now be specifically described by way of examples, but the present invention is not limited to these examples without departing from the gist of the present invention. (Example 1) A pattern is printed on a heat-resistant biaxially stretched polyester release sheet, and a polyvinyl chloride sol in which a stabilizer and a plasticizer are added to polyvinyl chloride is added thereto in an amount of 1 to 4 m.
A transparent paste-like material obtained by mixing 5 parts of transparent mica having a particle diameter of m was applied to the entire surface at a thickness of 500 μm, heated at 200 ° C., gelled, and then the polyester release sheet was removed to remove I got a makeup sheet. When this decorative sheet was adhered to a woody base material, a transparent and three-dimensional decorative material could be produced.

Example 2 A pattern was printed on the polyester release sheet used in Example 1, and then a transparent resin composition having the following composition was stirred for a few minutes, and then printed on the printed pattern. After coating and curing to form a transparent resin layer having a thickness of 400 μm, the polyester release sheet was removed to obtain a decorative sheet of the present invention. When this decorative sheet was adhered to a woody base material, a transparent and three-dimensional decorative material could be produced. Further, the scale partially reflected light in the transparent resin layer, and there was a crystal-like glittering feeling. Unsaturated polyester 93.3% by weight Mica having transparency (diameter 1.0 to 4.0 mm) 5.0% by weight Accelerator (6% cobalt nafurate) 0.3% by weight Reaction initiator (55% methyl ethyl ketone par) Oxide) 1.3% by weight
