2. Description of the Related Art In the case of a natural timber board, a long time is required for a long time on a surface formed by alternately arranging finely-grained timber portions and fine-grained timber portions that grow slowly and slowly. As the time elapses, the late wood portion rises more than the early wood portion, and a fine uneven shape synchronized with the grain pattern may be naturally formed. Such irregularities can be artificially exaggerated by rubbing the surface of a dry natural wood board with a paper file or the like. It can be seen in crafted wooden products. Until now, wood grain embossed decorative materials have been used for gravure printing, pipe embossing, surface roughening, to reproduce the grain or grain pattern, texture or texture, shine (glossy or gloss), etc. of natural wood boards. Techniques such as wiping have been used.

However, as the processing relating to the irregular shape of the wood grain embossed decorative material so far, the embossing of the pipe which reproduces a long elliptical pipe portion appearing on a natural wood board and the overall shine are performed. Wood grain embossed decorative materials that are mainly used for roughening the outermost surface for control and that attempt to reproduce the uneven shape formed according to the late wood part and the early wood part of the natural wood board are supplied. Absent. This is because the floating process itself was not known very much, and it was a blind spot in the reproduction of high-quality wood grain.
The embossing method which gives a height difference by accurately registering the wood pattern of the early wood portion S with a high reproducibility has not been established. The present invention has been made in view of this problem, and an object of the present invention is to provide a wood-grain embossed decorative material having a floating feeling by embossing with an embossing plate manufactured by a corrosion method.

FIG. 2 is a schematic sectional view of one embodiment of a wood grain embossed decorative material according to the present invention. The wood-grain embossed decorative material 10 according to this embodiment is formed by laminating an opaque colored plastic layer 1 and a transparent plastic layer 2 having a wood-grained printing ink layer 3 on the surface, and embossing the surface of the transparent plastic layer 2 by embossing. The early wood portions S adjacent to each other with the late wood portion B as a boundary are alternately recessed portions 5 and projecting portions 6.
As a result, an uneven appearance corresponding to the late material portion B and the early material portion S that does not have a visually unnatural feeling is formed on the entire surface. The printing ink layer 3 is
In addition to being provided on the surface of the transparent plastic layer 2, it may be provided on the surface of the colored plastic layer 1, or may be provided on both the colored plastic layer 1 and the transparent plastic layer 2. Further, in addition to the above, the conduit embossed portion 4 may be formed as usual, and the valley portion may be colored. Late part B
It is preferable that the wood printing ink layer 3 (3a, 3b) is synchronized, but it is not necessary to increase the tuning accuracy. This is because a slight shift in the positional relationship between the two does not give any sense of incongruity and has little effect on the visual effect for enhancing the texture of the natural wood grain. Further, the wood-grained printing ink layer 3 needs to be provided in the vicinity of the edge portion of the step at the boundary between the concave portion 5 and the protruding portion 6 having the uneven shape. In order to reproduce an appearance similar to that of a natural floating wood grain board without discomfort, it is necessary to use the late wood part B of the printing ink layer 3 having the wood grain pattern.
It is preferable that at least a part of the printing ink layer 3 a representing the wood grain pattern is provided so as to be located on the protrusion 6. (Refer to the left protrusion 6 in FIG. 2)

FIG. 3 is an explanatory view of the uneven shape of the wood grain embossed decorative material according to the present invention. The simplest model of the uneven shape of the surface of the wood embossed decorative material 10 according to the present invention is shown in FIG.
As shown in (a), the step between the two early wood parts S adjacent to the late wood part B is one step, and the height difference (that is, the level of the recess 5 and the protrusion 6) is uniform over the entire surface. There is a case where the average level L can be represented only by + (high) and-(low). FIG. 3B shows a case in which the steps of the two early wood parts S adjacent to each other with the late wood part B as a boundary are a plurality of steps, and the change in height is made closer to the density gradation of the boundary. FIG. 3 (c) shows a case where the level in each early wood portion S is not fixed, and a height difference is provided in the early wood portion S to further change the unevenness of the surface. On the other hand, ++, +, 0,-,-, etc. are represented in descending order. FIG. 3D shows the entire surface of the grain embossed decorative material 10 according to the present invention shown in FIG.
This is a case where the overall shine is controlled by adding fine irregularities such as a grain, a hairline, and a satin finish. The irregularities described above are provided by embossing the outermost transparent plastic layer 2. Generally, the thickness of the transparent plastic layer 2 is 30 to 70 in a V-shaped or U-shaped cross section.
The thickness is about 90 to 120 μm in consideration of the groove-shaped conduit embossed portion 4 provided at a depth of about μm. On the other hand, the uneven shape of the early wood portion S on the outermost surface is different from the uneven shape of the actual floating wood grain board. However, the height difference between the two early wood parts S adjacent to the late wood part B is preferably in the range of 10 to 100 μm, and in the range of 10 to 30 μm, while being a range that can be visually recognized, This is desirable because it is a range that does not cause discomfort. However, this step may be larger than the above range if the design and appearance are acceptable depending on the grain pattern or the observer's preference.

Hereinafter, a wood grain embossed decorative material 1 according to the present invention.
In the production of an embossing plate capable of forming an uneven shape on the surface of No. 0, the step between the early material portions S shown in FIG.
The case of a cross section model that changes in stages will be described as an example.
FIG. 4 is an explanatory diagram of a binarized image used for manufacturing an embossing plate according to the present invention. In order to obtain this image, first, a photograph is taken with a camera using the wood grain of a natural wood board as a manuscript, and an original film on which the wood grain image is recorded is created. Convert, convert to digital signals, read, store on hard disk and capture. The wood grain image may be directly converted to digital image data by using a digital camera instead of the above method, and this may be stored on the hard disk. The digital image information once stored by the above method is output to a display (CRT or the like) of the CEPS device. At this time, only the highest density point appearing at the center of the annual ring portion of the latewood portion B is extracted to obtain the boundary lines F1, F2, F3, and F4 ----, and further in the direction crossing the grain direction as shown in FIG. The corrected boundary lines F′1, F′2, F′3 −−− and the reduced corrected boundary lines F ″ 1 in which the distances between F1 and F2, F3 and F4,... , F "2, F" 3 ------
Is obtained, and 0 and 1 are alternately assigned to an area sandwiched by the modified boundary lines, thereby obtaining a binarized image as shown in FIG.
Can be output to the screen. The corrected boundary in the binarized image obtained in this manner is similar to a contour line of a map, and the binarized image and the image may be simultaneously output as different color patterns to the display. The above-mentioned binarized image, which is obtained straight using a natural wood board as a manuscript, has a boundary line (contour line) that is actually blurred or a portion of value 0 that should be outlined,
It is necessary to make sufficient corrections on the display screen because extra images may be included. Further, depending on a relatively simple woodgrain pattern, the binarized image may be artificially drawn by hand according to the woodgrain pattern projected on the display screen. The binarized image created as described above is stored in the hard disk.
Further, if the pipe is to be embossed, FIG.
The digital image data of the conduit image in which the conduit portions g to j shown in FIG. 3B are recorded is also stored.

FIG. 5 is an explanatory view of a process of manufacturing an embossing plate according to the present invention, and shows, in a schematic cross section, a time-series process change of the unevenness of the surface of the embossing plate. The elevation difference in FIG. 5 is exaggerated from the elevation difference of the actually processed early part S for easy understanding. First, a resist photosensitive liquid is applied to the embossed cylinder surface on which a copper ballad plating layer (a copper plating layer on the iron core material surface via a silver plating layer) is formed, and the binarized image shown in FIG. Is directly output to a cylinder surface by using a direct exposure device by laser beam scanning, and is burned and developed, and the early material portion S adjacent to the late material portion B as shown in FIG. The state is covered with the resist R.
The boundary points a to f in FIG. 5A correspond to the boundary points a to f on each boundary line F ′ in FIG. For this purpose, the region of value 1 in the binarized image of FIG. That is, when a negative resist photosensitive liquid is used, the laser beam is controlled so that the region of value 1 is exposed and the region of value 0 is not exposed.

The material 10 is obtained. Next, a resist photosensitive layer is formed again on the uneven surface, and the image shown in FIG. 4A is printed and developed in the same manner. As a result, the state shown in FIG. 5C is obtained. When the corrosion is performed and the resist is removed, an embossed plate E2 having a desired two-step height difference as shown in FIG. 5D is obtained. By preparing binary images of more combinations and performing multi-stage corrosion using them, it is possible to manufacture an embossed plate having a complex uneven surface as shown in FIG. 3 (c). . FIGS. 5 (5) and 5 (6) are explanatory views of further forming a convex portion for the conduit embossed portion 4 on the surface of the embossing plate E2, which is shown in FIG. 4 (b) on the surface of the embossing plate E2. If such a conduit pattern image is printed and the resist R is left only on the conduit portions g to j and the other portions are uniformly corroded, an embossed plate having a conduit convex portion 4 'for forming the conduit embossed portion 4 is formed. E3 can be manufactured. Finally, fine irregularities for controlling the illuminance are formed on the entire surface by a method such as sandblasting, and then finished by chrome plating. FIG. 5 (7) shows a cross-sectional shape of the transparent plastic layer 2 which is the base material of the wood grain embossed decorative material 10 according to the present invention, which is formed by embossing using the final embossing plate E3 by a known hot press method. I have. Further, when the embossing material 10 is laminated on the coloring sheet 5 simultaneously with or off-line from the embossing, the embossed decorative material 10 according to the present invention is obtained. Further, a backing material is attached according to the purpose of use. For example, when the embossed decorative material is a door, a core material of a door having a honeycomb structure may be bonded with a strong adhesive.

The above-described example is a case of embossing in a narrow sense in which an embossing plate is used to press and shape a heat-softened thermoplastic resin surface. However, the method for producing the embossed decorative material according to the present invention is not limited to this, and it can be produced by other methods. For example, an uncured liquid composition such as an unsaturated acrylate oligomer is applied to the surface of the embossed plate made by the above method, and at least the concave portion of the concavo-convex pattern is filled with the liquid composition, and then the resin is added to the liquid composition. The liquid composition is cured (individualized) by irradiating an ultraviolet ray or an electron beam from the sheet side in a state in which the sheets of the embossing plate and the like are brought into close contact with each other, and the liquid composition is adhered to the sheet surface, and the embossed plate is shaped into an irregular pattern. A method of releasing the cured layer from the embossing plate (disclosed in JP-A-2-131175) can also be used. Further, in the present invention, the substrate for shaping the concavo-convex pattern is polyethylene, polypropylene, polyolefin-based resin such as olefin-based thermoplastic elastomer, polyvinyl chloride, acrylic resin, thermoplastic resin such as thermoplastic polyester, melamine resin and the like. A material such as a thermosetting resin, an ultraviolet ray composed of an unsaturated acrylate, an epoxy or the like, or a cured product of an electron beam curable resin is used, and may be a single layer or a laminate of two or more layers. In addition, the unevenness having a height corresponding to the printing ink layer 3, the late material portion and the early material portion is effective for reproducing the design appearance of wood grain boards of various woods such as cedar pine and cypress.

According to the present invention, if necessary, a plurality of types of binarized images composed of the late wood portion B and the early wood portion S which are alternately arranged on a natural wood board are prepared, and these are sequentially subjected to the previous corrosion. By the multiple corrosion method of baking on the surface and corroding to substantially the same depth, it is possible to manufacture an embossing plate having an uneven surface with a height difference alternately between adjacent early material portions S with the late material portion B as a boundary, By shaping it on the base material of the decorative material using this, it is possible to provide the decorative material with a higher texture that the natural wood board has. Further, even if the registration (alignment) between the wood-grain pattern printing layer and the concavo-convex shape by embossing is shifted within the width of the latex portion B, it does not cause a sense of incongruity, and stable mass production can be performed.
