The paint is applied over the entire surface by printing or coating. As the transparent resin, it is preferable to use a two-component curable urethane resin or the like in order to improve the surface performance of the decorative sheet. Since the conduit pattern printing layer is also provided on the gloss adjusting transparent resin layer, it is preferable to use a two-component curable urethane resin or the like as described above for the ink vehicle.

The uneven pattern has a height difference between the concave portion and the convex portion of 3 to 50 μm and an interval between the concave portions of 1 to 50 μm. It consists of a parallel curve group of 1000 μm or a combination of a parallel curve group and a parallel straight line group. And
The parallel curve group connects curves such as sine wave, cycloid, elliptic function, Bessel function, etc. and arranges them in parallel, or the function curve is divided into equal intervals by changing its parameters, Are formed so as to change smoothly in the line direction.

この角度は、必ずしも限定するものではない。The pattern and direction of illumination of a natural woodgrain board varies depending on the type of wood, the portion of the wood, and the cutting direction. Therefore, the flow direction of the printed grain pattern and the flow direction of the uneven curve are, for example, when orthogonal, the pattern of shining that appears is vertical shining along the direction of the grain pattern, but on a natural board it is a tiger spot. There is also a so-called lateral illumination, and in this case, it is necessary to make the flow direction of the grain pattern and the flow direction of the uneven curve parallel. Therefore,
This angle is not necessarily limited.

用することもできる。Here, a brief supplementary explanation will be given of a method of making a gravure plate of the pattern A and the pattern B.
First, a maple natural wood grain board is used as a document, placed in front of a camera, and a light source is installed at an angle at which illuminance can be effectively observed, and photographing is performed using a negative film. Only the reflected light portion of this negative image is extracted, and a negative image of the entire illuminated light whose pattern is shown as a model diagram in FIG. 3A is created. Next, based on the negative image, a scanner is read into two parts, a bright part and a weak part, on the basis of a substantially intermediate value of the density, and the patterns are shown in (b) and (c) of FIG. A film with two types of black patterns as shown in the model drawing of FIG. (B) is the pattern of the strong shining part.
(C) is a pattern of the second bright print layer, which is a pattern of a weakly illuminated portion. Using the two types of black pattern films created in this way, register each with the wood grain pattern plate,
Exposure, development, etching, plating, and polishing were performed by a printing plate method using a normal carbon tissue to prepare printing plates for pattern A and pattern B. The shapes of the patterns of the first and second glitter print layers are used in the present embodiment, and are not limited thereto. For example, the entire pattern shown in FIG. 3A can be used as the picture pattern of the second glittering print layer.

である。On the printing surface of the printing sheet thus obtained, a fine irregular pattern of a pattern consisting of a group of sine-curved parallel curves was formed at a heating temperature of 165 ° C., a speed of 10 m / min, and an embossing pressure of 4 kgf / cm 2. Using the provided embossing plate, embossing was performed by aligning the grain direction and the sine curve-shaped embossing line so as to be parallel.
The height of the linear projections of this embossing plate is 12 μm,
The interval between the convex portions is 70 μm. In addition, the uneven pattern provided on the print sheet by this embossing is shown in FIG.
As shown in the above, the ink reached the interface between the first glittering printing layer and the transparent thermoplastic resin film through each printing layer.
This state is the most preferable state for expressing illuminance.

が得られた。Further, a two-part curable urethane resin-based paint containing a matting agent such as silica is applied as a gloss-adjusting transparent resin layer on a surface opposite to the embossed surface of the printed sheet by a roll coater. Using a two-component curable urethane resin-based pattern ink having a gloss lower than that of the gloss-adjusting transparent resin layer, a wood grain conduit pattern was printed to obtain a decorative sheet of the present invention. In the decorative sheet obtained in this way, there is horizontal gradation with gradation close to that of a decorative material using natural maple,
The movement of the shining was also synchronized with the pattern, and an unprecedented design was obtained.

The embossed fine uneven pattern is constituted by a parallel curve group or a pattern combining the parallel curve group and the parallel straight line group, the difference in height between the concave portion and the convex portion is 3 to 50 μm, and the line interval for forming the concave portion is 1.
A configuration provided so as to be in the range of up to 1000 μm is adopted.

た効果を奏するものである。By adopting such a configuration, the first glittering print layer gives a strong shine and the second glitter print layer gives a weak shine, and the gradation of the gradation synchronized with the picture is obtained. The expression of a certain shine was made possible. In addition, a fine uneven pattern by embossing is added to this, it is possible to obtain the movement of illuminance synchronized with the pattern and the expression of three-dimensional effect, and it is easy to obtain a decorative sheet with a high design that is extremely similar to the decorative material of natural wood. It has excellent effects.
