  The glittering decorative board of Conventional Example 1 is provided with a transparent resin composition blended with scales such as mica and glass flakes in a pattern layer, and the scales are dispersed in the surface layer so that light is scales in the surface layer. The effect of reflecting and giving a glittering feeling is obtained, but only the scales are dispersed in one layer, and the reflection of light may be monotonous. In particular, the scale has a maximum diameter of 0.3 to 0.3 mm. With such a glittering decorative board, the brilliantness is emphasized and it is difficult to always bring out a high-class depth.

  Further, in the glittering decorative board of Conventional Example 1, it is conceivable to increase the thickness of the transparent resin composition to foster a sense of depth, but the base material of the decorative board is flexible paper, synthetic resin, etc. In this case, since storage, transportation, and the like are usually performed in a roll shape, there is a possibility that a fine crack may occur in the transparent resin layer in order to increase the thickness of the transparent resin layer and thereby create a deep feeling. Of course, even when storing and transporting in the form of a sheet, it is not preferable to increase the thickness of the transparent resin layer because of the disadvantage that the surface of the glittering decorative board is easily damaged.

  In addition, the glittering decorative board of Conventional Example 2 is obtained by forming an uneven resin layer, forming an intermediate coating layer with an acrylic resin, and forming a finished mirror surface layer, and the sense of depth must depend on the thickness of the resin. In order to foster a deeper feeling, it was necessary to further increase the thickness of the resin, but the same problem as described above occurred, and the thickness of the uneven resin layer and the finished mirror surface layer by the transparent resin layer was reduced. There was a limit to how thick and deep it can be.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a glittering decorative board having an excellent design that can make a glittering resin layer thinner and a deeper feeling than before. It is what.

The present invention achieves the above-mentioned problems, and the invention according to claim 1 is provided on the functional concealment layer and the functional concealment layer for concealing the color tone of the base material provided on the base material. a first shiny layer containing a brilliant pigment, and a second bright layer containing a large bright pigment of particle size than the bright pigment of the first brilliant layer, provided on the second photoluminescent layer, visible light a bright decorative plate to the transparent colored layer half a pigment dispersed a particle size of less than or equal to adjust the color tone of the wavelength of said Rukoto such provided.

Further, the invention of claim 2 is characterized in that the pigment contained in the second glitter layer is a film obtained by applying a holographic process into 30-200 μm strips. It is a decorative decorative board.

  Hereinafter, an embodiment of a glittering decorative board according to the present invention will be described with reference to FIG. In the present embodiment, a concealing layer 13 such as impregnated paper is adhered to the base material 11 with an adhesive layer 12, and a glitter resin containing a fine glitter pigment is applied on the concealment layer 13 by printing or the like. The 1st glitter layer 14 is formed, and further, a glitter pigment containing the glitter pigment b with the glitter pigment a is blended by printing or the like to form the second glitter layer 15, and the second glitter layer 15 is formed. A transparent colored layer 16 made of a resin having a pigment dispersed thereon is formed. On the transparent colored layer 16, a transparent mirror finish layer 17 and a hard coat layer 18 are sequentially laminated. In addition, if the smoothness of the surface of the transparent colored layer 16 is good, the transparent mirror finish layer 17 is not necessary, and if it has a predetermined hardness required as a decorative board, the hard coat layer 18 is not necessary. .

  The base material 11 in the above embodiment may be any of wood-based, paper-based, metal-based, or inorganic-based materials, and may be appropriately selected depending on the application. Illustrative examples include medium density fiberboard (MDF), plywood, metal board, paper, wood, slate, calcium silicate board, particle board, gypsum board and the like.

  The concealing layer 13 conceals the color tone of the base material 11 itself and the pigment of the adhesive layer 12, flattens the unevenness of the base material 11, and reinforces the strength of the base material 11. The concealing layer 13 is a functional concealing layer for providing a shielding effect such as electromagnetic waves and moisture as required. The adhesive layer 12 may be an adhesive that bonds the base material 11 and the masking layer 13 together.

  The first glitter layer 14 is a resin in which the glitter pigment a is blended, and the glitter pigment a is a mica-based pearl pigment, aluminum powder, a glitter pigment obtained by finely cutting aluminum deposited on a polyester film, or Examples include a metal-deposited sheet (paper or film), a metal stay, a cut piece obtained by finely cutting a metal plate and the like. The glitter pigment a has a distribution with a maximum dimension of approximately 10 to 100 μm.

The second glitter layer 15 is a layer printed or coated with a resin blended with the glitter pigment b. As the glitter pigment b, those similar to the above can be used. The particle size is larger than that of the luster pigment a, and generally has a maximum size distributed around 80 μm. Of course, the maximum dimension of the glitter pigment b may be determined in accordance with the dimension of the glitter pigment a of the first glitter layer 14. For example, if the maximum dimension of the glitter pigment a is 10 μm, the glitter pigment b is It is sufficient that the maximum dimension is distributed around 50 μm. The glitter pigment b of the second glitter layer 15 is, for example, a film obtained by applying a holographic process into pieces of 30 to 200 μm, and the pigment is a slab of a film subjected to the holographic process. Therefore, incident light is reflected on the pigment surface, collimated light interferes and interference fringes are generated, and the second glittering layer becomes a layer that produces a rainbow color, creating a higher-class feeling and excellent design. It can be a glittering decorative board.

  On the other hand, the combined thickness of the first bright layer 14 and the second bright layer 15 is several μm. The method of laminating the first glitter layer 14 and the second glitter layer 15 is preferably a silk screen printing method, a gravure printing method, or the like, but a coating method, a film method, or a resin sheet containing the glitter pigment a or b (for example, It is also possible to form by a method of laminating a (brilliant resin sheet). When a glittering resin sheet is used as the first glittering layer, the concealing layer may be omitted and the glittering resin sheet may be directly attached to the substrate.

  Furthermore, the 2nd glitter layer 15 is good also as a design layer which printed the pattern by the glitter pigment containing the glitter pigment b. The design layer includes, for example, vertical or horizontal stripes, a checkered pattern, and a design with a motif of nature or an artificial object such as a grove. Of course, the first glitter layer 14 may be a pattern, the second glitter layer may be interspersed with glitter pigments, or a pattern may be a combination of the first glitter layer 14 and the second glitter layer 15.

  The transparent colored layer 16 is obtained by dispersing a transparent pigment in a transparent vehicle (color developing agent mixed with an oil agent or a transparent resin) having adhesiveness with the second bright layer 15. Of course, a dye may be used if transparency is obtained. The transparent colored layer 16 may be a pigment having a particle diameter that transmits light having a wavelength of 1/2 or less of the wavelength of visible light. If the color developing agent and the pigment or dye are mixed, the transparent colored layer 16 is almost transparent. Good.

  The transparent mirror finish layer 17 is made of an unsaturated polyester resin, UV (ultraviolet) curable resin, urethane paint, or the like, and an ultraviolet absorber is blended as necessary. In order to improve the adhesion between the transparent mirror finish layer 17 and the transparent colored layer 16, a transparent varnish or paint may be provided as a primer layer. Further, a hard coat layer 18 is formed on the transparent mirror finish layer 17. The hard coat layer 18 is provided to obtain a necessary surface hardness as a glittering decorative board, and the hard coat layer 18 is not necessarily provided. Further, a mirror film may be laminated on the second bright layer 15. At that time, a primer layer is formed to enhance adhesion.

  In the present embodiment, the blending ratio of the glitter pigments a and b in the first glitter layer 14 and the second glitter layer 1 is appropriately determined. For example, the content of the glitter pigment b contained in the second glitter layer 15 can be set such that the first glitter layer 14 can be visually recognized from between the pigments.

  While explaining the glittering decorative board of the present example, a number of materials were prepared and compared for verification of the superiority of the depth feeling of the present example. The glittering decorative board of this example will be described with reference to FIG. 1. The base material 11 has a white surface, and a concealing layer 13 is formed by an adhesive layer 12 having a light yellow hue. For the masking layer 13, paper whose surface is colored green is used.

  On the concealing layer 13, a first glitter layer 14 made of a glitter resin containing the glitter pigment a was formed by silk screen printing. The first bright layer 14 was a layer that colored yellow. As the glitter pigment a of the first glitter layer 14, a mica-based pearl pigment having a maximum dimension in the range of 10 to 60 μm was used. The mesh of the cocoon by silk screen printing may be any of 80M, 100M, 150M, and 180M (M: mesh, number of yarns per inch). Of course, it is not limited to silk screen printing, and any of gravure method, coating method, and film method may be used.

  Subsequently, a glitter resin in which a glitter pigment b having a particle diameter larger than that of the glitter pigment a was blended on the first glitter layer 14 was performed according to the above-described formation method, thereby forming the second glitter layer 15. The second glitter layer 15 was a pink layer. As the glitter pigment b of the second glitter layer 15, a mica pearl pigment was used, and a cut piece having a maximum dimension distributed around 80 μm was used.

  Next, a transparent colored layer 16 was formed by applying a resin in which a pigment was dispersed on the second bright layer 15. The transparent colored layer 16 was a layer that developed red. The method for forming the transparent colored layer 16 is a coating method, but may be any method such as a silk screen printing method or a gravure printing method. The purpose of the transparent colored layer 16 is to adjust the thickness of the transparent colored layer 16 so as to moderately attenuate the reflected light of the bright pigments of the first bright layer 14 and the second bright layer 15 to create a deep and high-class feeling. The transparent colored layer 16 may be finely adjusted in color tone by overprinting. On the transparent colored layer 16, a transparent mirror finish layer 17 was laminated.

  The transparent mirror finish layer 17 was mirror-finished by a film method using unsaturated polyester. Of course, an acrylic resin may be used, or a transparent layer may be formed by painting, and mirror finishing may be performed using a UV (ultraviolet) curable resin. A sample was prepared in this way, and as a comparative sample, as shown in Table 1 below, a sample was prepared by omitting any layer or mixing adjacent layers. No. No. 7 is the present example, and other Nos. 1-6 and 8-15 are comparative samples.

  As shown in Table 1, no. Samples 4, 5, and 9 have a feeling of depth because they contain glittering pigments, but have a disadvantage that the color tone is poor, the intended color tone cannot be obtained, and the high-quality feeling is poor. In particular, no. Sample No. 9 is a layer formed by mixing the luster pigments a and b. The luster pigments a and b having different shapes are mixed, and there is a sense of depth, but there is a variation in the depth. It was. No. Sample No. 7 was the glittering decorative board of this example, and was a glittering decorative board finished in a deep red color and having a well-designed color tone.

  The glittering decorative board of the present invention has a first glittering layer 14, a second glittering layer 15, a colored transparent layer 16, and a transparent mirror surface layer 17 that are sequentially laminated on the concealing layer 13 of the substrate 11. The color tone can be easily adjusted, and the fine glitter pigment a is dispersed in the first glitter layer 14, and the coarse glitter pigment b is dispersed in the second glitter layer 15. The light incident from the surface is reflected by the glitter pigment a, and the reflected light is radiated from between the glitter pigment b through the second glitter layer 15, the colored transparent layer 16, and the transparent mirror layer 17 to be emitted. Parallel light is radiated to the reflected light reflected from the surface of the glitter layer 14. Further, the reflected light of the glitter pigment a includes parallel light with respect to the reflected light of the interface of each layer such as the interface between the first glitter layer 14 and the second glitter layer 15. Further, the light reflected by the glitter pigment a is reflected by the back surface of the glitter pigment b, reflected again by the glitter pigment a, emitted from between the glitter pigments b, and parallel light is emitted with respect to the incident light, The light reflected by the glitter pigment b is emitted from the surface. The reflected light from the glittering decorative board causes interference to produce a design surface with a sense of depth.

  Thus, in the glittering decorative board of the present invention, the total film thickness of the first glittering layer 14 and the second glittering layer is several because the reflected light of the surface of each layer and the glittering pigments a and b interfere with each other. Even if it was μm, it was excellent in design with a deep feeling. Furthermore, by forming the colored transparent layer 16, the color tone was adjusted, and a glittering decorative board having further excellent design properties was obtained.

  The present invention can be used not only as an interior material as a building material but also widely used in ships, vehicles, aircraft, furniture, and the like.
