BEST MODE FOR CARRYING OUT THE INVENTION The decorative plate of the present invention is a decorative member having a transparent member having an irregular design surface and a colored coating, wherein the colored coating is provided on the transparent member having an irregular design surface. It is provided in.

The transparent member is made of a synthetic resin such as plastic or inorganic glass.
There is no particular limitation as long as the other side has such transparency that it can be seen through. The transparent member may be colorless, or may be colored as long as the transparency is maintained. By being colored, the design can be enhanced.

This transparent member has an uneven design surface. Here, the concavo-convex shape means that the height difference between the concave portion and the convex portion is 0.005 mm or more. This height difference,
It varies depending on the thickness of the transparent member, and is usually preferably 5 to 100% of the thickness of the transparent member. By increasing the height difference, a three-dimensional design can be easily obtained. In addition, the thickness of the transparent member of the present invention means the maximum value of the distance between the convex portion and the surface located on the opposite side of the concave-convex shape design surface, according to the article on which the decorative board is installed. Although it can be determined, for example, the thickness can be 0.5 to 100 mm.

The uneven shape represents a surface condition of paper, cloth, leather, woven fabric, etc., a shape representing sand, stone, etc.
Geometric patterns such as cross-stitch and patterns such as checkered patterns, specific objects, substances, characters,
It may be a design showing characters or the like. These designs may show a logo as a character, a mark combining character and a figure, an emblem, or the like. 1 to 6 and 15 and 16 show some examples of these.

Further, the uneven shape may exist on the entire surface including the uneven surface, or may exist partially. That is, the decorative plate having the uneven shape may be, for example, a surface, plate, plate, or the like having the above-described state or pattern. When the uneven shape indicates a specific object, substance, character, character, or the like, the uneven shape may be an independent uneven shape cut out from a plane including these. It should be noted that the decorative plate in the present invention includes a design formed on the decorative plate as described above and cut out according to its shape.

When the above-mentioned uneven shape is present on the entire surface, it is preferable that the uneven shape is formed continuously with regularity. More preferably, it is 50 mm. A three-dimensional design can be obtained by forming the irregularities continuously with regularity. As an example, it is possible to show the surface state of the woven fabric as shown in FIG. 2 or the geometric pattern shown in FIG.

On the other hand, when the uneven shape is partially present, the uneven shape may be arbitrarily formed according to the design.

The uneven shape may be constituted by a straight line, but is preferably constituted by a curved line or a curved line and a straight line in order to obtain a more three-dimensional design.

The surface located on the opposite side of the uneven design surface may be a flat surface or a curved surface, and is selected in order to obtain a desired design, but when a special design is not required. Is preferably a flat surface. The plane referred to here includes a gentle curved surface. In addition, as long as the transparency is not hindered, it is also possible to form a concavo-convex shape, which is the same as or different from the concavo-convex design surface, on a surface located on the opposite side of the concavo-convex design surface in order to enhance the design property.

A protective layer may be provided on the surface located on the opposite side of the uneven design surface to protect the surface during transportation of the decorative plate. This protective layer is preferably colorless and transparent, and examples thereof include a transparent film and a clear coating film. When the protective layer is a film, the protective layer may have a property capable of being peeled off. The protective layer can be formed by attaching a film, applying a clear paint, or the like.
The protective layer can be formed at any stage when the decorative board of the present invention is manufactured. For example, the protective layer may be formed before or after forming the uneven shape.

The above transparent member can be obtained by various methods. For example, when the material of the transparent member is inorganic glass, an irregular design surface is formed by cutting or blasting one surface of a glass plate having a predetermined size. At this time, the other surface becomes a plane. As described above, this plane can be processed in the same manner.

Further, when the transparent member is a thermoplastic resin such as plastic, like the above-mentioned inorganic glass,
Although it is possible to cut one side of the plate material, a transparent member constituting the decorative plate of the present invention can be obtained by injection molding using a mold having an uneven shape.

Further, it is possible to three-dimensionally pattern the photocurable material. In this case, a method of irradiating a photosensitive material including a photocurable material with a light beam corresponding to the uneven shape and sequentially curing the portion with a light beam or a method of performing a development process after irradiating the light beam to form an uneven shape is used. Can be used.

As a method of three-dimensionally patterning such a photocurable material, a method described in JP-A-11-009233 can be used. According to this method, first, three-dimensional digital image data captured using a CCD or the like or three-dimensional digital image data created on a desktop is two-dimensionalized using mapping conversion software. Next, a mask film having a gradation is prepared based on the data, and a three-dimensional resin is obtained by irradiating a light beam such as an ultraviolet ray to a photosensitive material including a photocurable material using the mask film. By using this method, a transparent member having an uneven design surface can be obtained.

For example, FIGS.
Three-dimensional digital image data in which a circle, a line, a wave, and an inclination are captured using a CCD camera are displayed in the form of a wire frame, and FIGS. 8, 10, 12 and 14 show two-dimensional representations of these data. . From these, a mask film having a gradation is produced, and a photosensitive material including a photocurable material is irradiated with ultraviolet rays using the mask film.
It has the same shape as 9, 11, and 13. A complex shape can be expressed by combining these circles, lines, waves, and inclinations. As described above, it is preferable to use this method because a free irregularly shaped design surface including a curve can be created.

In addition, this method can easily form an inverted concavo-convex shape using the above digital image data. Available. In this method, when a material having a transparent base film such as PET is used as a photosensitive material for forming the transparent member, the obtained transparent member is formed on the opposite side of the uneven design surface. A transparent base film is located. As described above, a transparent film may be provided on the surface of the transparent member opposite to the concave-convex shape design surface.

[0026] In the decorative plate of the present invention, the colored coating film is provided on the uneven design surface of the transparent member.
The colored coating film may be a coating film containing a general coloring pigment. Examples of such coloring pigments that have been conventionally used for paints include, for example, azo lake pigments, phthalocyanine pigments, indigo pigments, perylene pigments, quinophthalone pigments, dioxazine pigments, quinacridone pigments, and isoindo pigments. Linone pigments, metal complex pigments, graphite, yellow iron oxide, red iron oxide, titanium dioxide, carbon black and the like can be mentioned.

When a higher design property is required, the colored coating film is preferably a glitter coating film, and more preferably a dichroic coating film or a polychromatic coating film. The brilliant coating film contains a brilliant pigment and, if necessary, a coloring pigment. Such brilliant pigments, which are conventionally used for paints, include, for example, aluminum flake pigments, colored aluminum flake pigments, graphite pigments, mica pigments, interference mica pigments, colored mica pigments, alumina flake pigments, titanium metal flake,
Examples include stainless flake, plate-like iron oxide, phthalocyanine flake, metal oxide-coated silica flake pigment, metal-plated glass flake, light interference pigment, and hologram pigment.

The dichroic coating film is a coating film containing a brilliant pigment capable of exhibiting a flip-flop property. The dichroic coating film has a different appearance when viewed from the highlight position and when viewed from the shade position. , Two colors depending on the viewing angle. Such a coating film can be obtained by orienting a flat pigment in the glittering coating film.

On the other hand, a polychromatic coating film is obtained by orienting a brilliant pigment having a hue change of two or more colors in the coating film. The color tone of the dichroic coating is 2
In contrast to the color, in the case of this polychromatic coating film, two or more hue changes are obtained depending on the viewing position. Examples of such a glitter pigment include a light interference pigment obtained by pulverizing a multilayer thin film interference coating and a hologram pigment obtained by pulverizing a hologram described in Japanese Patent Publication No. 9-508172. it can.

Further, in order to enhance the design, the coloring pigments and the brilliant pigments contained in the above-mentioned colored coating film can be used in combination of plural kinds. Further, a functional pigment such as a luminous pigment may be contained.

The thickness of the colored coating film in the decorative board of the present invention is not particularly limited, but is preferably, for example, 5 to 100 μm.

The colored coating film can be formed by applying a coating material for forming a colored coating film on the concave and convex design surface of the transparent member. The paint for forming the colored coating film may be a usual paint containing the above-mentioned coloring pigment and / or glittering pigment. The paint for forming the colored coating film may be a commercially available one. For example, as a paint for obtaining a multicolored coating film, Nippon Paint's "Majora" series can be mentioned. .

In the decorative plate of the present invention, when the uneven shape is partially present on the design surface of the uneven shape, the portion where the uneven shape does not exist can be further colored by means such as painting. . On the other hand, in this case, it is also possible to paint and color the portion having the uneven shape using a paint such as a phosphorescent paint.

By applying these colors, when the colored coating film is viewed through a transparent member described later, the contrast between the uneven portion and the other portion is enhanced, and the design can be improved. In addition, when the above-mentioned luminous paint is used, a unique design can be created in which characters and designs emerge or disappear due to a difference in design properties between a state where light is irradiated and a state where light is not irradiated.

Further, in the decorative plate of the present invention, a layer for protecting the colored coating, a layer for reflecting light incident from the transparent member side, a colored layer for enhancing design, and the like are provided on the colored coating. Further, they may be formed, and these can be formed by applying a coating material corresponding to each layer.
