ない。DESCRIPTION OF THE PREFERRED EMBODIMENTS The substrate used in the decorative board of the present invention is not particularly limited. Board, perlite board, plaster board,
Examples include a wood chip cement board and the like, and a volcanic glassy multilayer board. In particular, when an architectural plate is used as the base material, the surface may be smooth or may have an uneven shape. In order to reinforce the surface of the substrate, it is preferable to perform an impregnated sealer treatment in which an impregnated sealer is applied to the surface of the substrate and cured. When it is necessary to increase the smoothness of the surface of the base material, a sealing treatment is performed. The filling process can be performed by a conventionally known method. For example, the surface of the base material is ground by a grinder, a moisture-curable sealer diluted with a thinner is applied to the base material, and dried. The filling process is completed by hardening the stopper and further polishing the surface. Even if the surface of the base material is provided with a concavo-convex shape, a so-called deep feeling can be given to the surface of the decorative board. In this case, the difference in the thickness of the base material from the bottom of the recess to the top of the protrusion is 150 μm. By forming the following, when forming a top clear layer described later, the surface thereof is smooth, and further effects are obtained in combination with the deep feeling of depth by the plurality of decorative layers and the transparent layer disposed therebetween. It can be obtained without impairing the surface smoothness.

感に優れるものであり、また平滑性も良好であった。The present invention will be further described below with reference to examples. (Example 1) A calcium silicate plate having a bulk specific gravity of 1.1 and a thickness of 6 mm was used as a substrate, and an isocyanate impregnated sealer (trade name: E-1 manufactured by Nippon Paint Co., Ltd.) was applied to the surface of the substrate.
(00 sealer) was applied and cured to perform an impregnated sealer treatment. Next, the surface of the base material is polished with a polishing machine, and a moisture-curable urethane sealer diluted by 50% with a thinner for urethane is applied at a rate of 90 g / m 2 and dried, and an ultraviolet-curable polyester filler is applied to the coated surface. Is applied at a rate of 90 g / m 2 using a roll coater,
The filler was cured by irradiating ultraviolet rays, and the surface was polished to complete the filler. Next, 60 g of an acrylic urethane resin paint (manufactured by Nippon Paint Co., Ltd.) was applied on the base material subjected to the filling process by a flow coater method.
/ Was applied at a rate of m 2, dried, thickness and cured of 30μm
Was provided with a white first decorative layer. Subsequently, an acrylic UV-curable resin clear (Nippon Paint Co., Ltd.) is placed on the first decorative layer.
Co., Ltd.) was applied at a rate of 30 g / m 2 by a flow coater method, and the resin was cured by irradiating the substrate with ultraviolet rays at 120 W / cm while moving the substrate at 6 m / min.
A first transparent layer having a thickness of 30 μm and a total light transmittance of 90.6% was provided. Next, an acrylic UV-curable resin paint (manufactured by Nippon Paint Co., Ltd.) is printed on the first transparent layer by a screen printing method, and ultraviolet rays of 120 W / cm are applied while moving the substrate at 6 m / min. By irradiating the resin under the conditions and curing the resin in two plates, the pattern is a sandstone-like pattern based on dark gray as a pattern, and has a thickness of 8 μm.
Was provided. The paint used for the first edition and 2
The color tone of the paint used for the plate was slightly different, and the sandstone-like pattern was formed by overlapping these two plates. Subsequently, an ultraviolet curable resin (manufactured by Nippon Paint Co., Ltd.) was applied on the second decorative layer by a flow coater method at 45 g / m 2.
The composition was applied at a rate of 2 and the substrate was irradiated with ultraviolet rays at 120 W / cm while moving the substrate at 6 m / min to cure the resin and provide a top clear layer having a thickness of 45 μm. The top clear layer is translucent containing a pale yellow color pigment at a content of 1.5% by weight (total light transmittance is 52.1%). The decorative plate of the present invention obtained in this way was superior in depth to which the shadow was emphasized, and also excellent in smoothness as compared with the conventional decorative plate.

った。Example 2 Example 1 was repeated, except that the decorative board manufactured in Example 1 was changed as follows. That is, an acrylic UV-curable resin clear (manufactured by Nippon Paint Co., Ltd.) was applied on the second decorative layer at a rate of 30 g / m 2 by a flow coater method, and
Ultraviolet rays were irradiated at 120 W / cm while moving at m / min to cure the resin, and a second transparent layer having a thickness of 30 μm and a total light transmittance of 90.6% was provided. Also, the second
Acrylic UV-curable resin paint (manufactured by Nippon Paint Co., Ltd.) was printed on the transparent layer by screen printing to form a sandstone-like pattern based on light gray as a pattern.
Ultraviolet rays were irradiated at 120 W / cm while moving at m / min to cure the resin, and a 5 μm-thick third decorative layer was provided. Further, the same top clear layer as in Example 1 was provided on the third decorative layer. The decorative plate of the present invention obtained in this manner was more excellent in depth with a more emphasized shadow than that of Example 1, and also had good smoothness.
