2. Description of the Related Art Conventionally, as a decorative material having a fine line-shaped unevenness formed on a surface, for example, Japanese Patent Application Laid-Open No. 4-521 is disclosed.
As described in Japanese Patent Publication No. 81, the surface of the base material includes an uneven shape for reproducing the original surface shape, and a parallel line group and / or a parallel curve group for reproducing the original surface gloss and its anisotropy. There is known a decorative material in which the concave and convex shape of the fine parallel groove is formed.

In the conventional decorative material as described above, the uneven shape of the fine line groove is provided on the entire surface of the decorative material, that is, in both the convex portion and the concave portion of the surface, so that the convex shape of the surface is increased. The unevenness of the fine line groove formed in the portion has a disadvantage that it is easily damaged by abrasion, and as a result, gloss unevenness tends to occur. In addition, there is a disadvantage that the surface gloss and texture of the original form cannot be accurately reproduced because the unevenness of the fine line grooves is formed on the entire surface of the decorative material, so that there is little difference in the surface gloss between the convex and concave portions. Was.

[0004]

It is an object of the present invention to have a surface texture, texture and gloss very similar to wood, and in particular this gloss moves according to the viewing direction and varies in strength. While reproducing well,
An object of the present invention is to provide a decorative material in which the texture of wood is hardly impaired due to surface wear.

[0005]

Means for Solving the Problems The surface is composed of a flat portion and a concave portion corresponding to a wood tissue conduit, temporary conduit, fiber or the like, and the concave portion is formed with parallel fine irregularities composed of a group of parallel lines. It is a decorative material characterized by the above.

[0006] The above-mentioned decorative material is characterized in that grain-like irregularities are formed on a flat portion of the surface.

[0007] In the above decorative material, a protective layer is provided so as to cover the entire surface of the flat portion and the concave portion.

[0008]

A parallel line group (a parallel line group is a line group consisting of a plurality of parallel straight lines or parallel curves, or a crossing between two adjacent lines is not constant, but is not fixed). Line group consisting of a plurality of straight lines or curves), the surface texture of wood, texture and other textures can be faithfully reproduced.
The texture of the wood is hardly impaired by the abrasion of the surface, and a cosmetic material excellent in both physical properties and design can be obtained.

The protective layer improves the surface properties of the decorative material 1 and adjusts the surface gloss. As the resin used as the protective layer, a urethane thermosetting resin, an ultraviolet curable resin, or the like is suitable. I have. In order to adjust the surface gloss, it can be arbitrarily carried out by adding an inorganic fine powder such as calcium carbonate, barium sulfate, silica, alumina or the like to the above-mentioned thermosetting resin or ultraviolet curing resin.

As shown in FIG. 5, a decorative material 1 'according to another embodiment of the present invention has a flat portion 2 and a concave portion 3 corresponding to a temporary pipe of wood tissue, fibers, etc., as shown in FIG. The surface of the flat portion 2 is formed with grain-like irregularities 5, and the concave portion 3 is formed with line-like fine irregularities 4 formed of parallel lines on the bottom surface. With this configuration, the grain-like unevenness 5 is formed on the flat portion 2, so that gloss and texture closer to the wood grain board surface can be obtained.

As shown in FIG. 6, a method for manufacturing an embossing plate for manufacturing the decorative material 1 of the present invention in which line-shaped fine irregularities 4 are formed on the bottom surface of the concave portion 3 on the surface first forms the embossing plate. After a photosensitive agent is applied to the copper surface of the metal base material and exposed and developed by a mask film having line-shaped fine irregularities 4, the surface is exposed to etching as shown in FIG. To form Next, line-shaped fine irregularities 4
A photosensitizer is applied to the copper surface of the metal substrate on which is formed a metal film so as to completely cover the line-shaped fine irregularities 4 on the surface, and a mask film for forming the concave portions 3 corresponding to the grain formed on the surface is used. Exposure and development are performed to form a resist film corresponding to portions other than the portion where the concave portion 3 is to be formed, and the state shown in FIG. By etching the surface in the state shown in FIG. 6B, line-shaped fine irregularities 4 are formed on the surface of the projection.
The concavo-convex shape of the embossing plate shown in (c) is completed. Thereafter, chrome plating is performed on the copper surface of the embossed plate base material shown in FIG. 6C to complete the embossed plate.

A method of manufacturing an embossing plate for manufacturing a decorative material 1 'of another embodiment shown in FIG. 5 of the present invention is shown in FIG.
(C) The embossed plate concave portion is further changed from the state shown in (c).
When chrome plating is performed in a state where only the resin 17 is filled, and the resin filled in the concave portions 17 of the embossing plate is removed, chrome plating is applied only to the convex portions of the embossing plate where the line-shaped fine irregularities 4 are formed. By sandblasting in this state, grain-like irregularities are formed only in the embossed plate concave portions 17. Next, the chrome plating remaining on the protrusions is removed, and the chrome plating is performed again on the entire surface to complete the embossed plate.

The surface shape of the embossing plate is transferred to the surface base material layer 11 by embossing the surface of the surface base material layer 11 with the embossing plate shown in FIG. The decorative material 1 of the present invention having the surface shape on which the linear fine irregularities 4 are formed is obtained.

In the method for producing the decorative material 1, a printing ink layer 12 composed of a pattern ink layer and a solid ink layer is provided on the surface of the colored back substrate layer 13 by printing. Ordinary embossing in which a transparent front substrate layer 11 is superimposed on the printing ink layer 12 of the back substrate layer 13 provided with the printing ink layer 12 and an embossing plate having the shape shown in FIG. The embossing is performed on the surface of the transparent surface base material layer 11 by using a printing machine, and at the same time, the back surface base material layer 13 provided with the printing ink layer 12 and the transparent surface base material layer 11 are bonded and laminated. The transparent protective layer 14 is provided on the entire surface of the finished surface to complete the decorative board.

In the case of using a single layer of the front substrate layer 11 without using the rear substrate layer 13, the embossing plate is provided after the printing ink layer 12 is provided on the front or back surface of the front substrate layer 11. Then, embossing is performed from the surface of the surface base material layer 11 to produce a single-layer decorative material.
