れる。Figure 1 (A) shows a state in which a wooden material 1 is impregnated with a synthetic resin 2. Examples of the synthetic resin 2 include polymerizable monomers and prepolymers, such as polymerizable resins such as unsaturated polyester. . Methods for impregnating such synthetic resins include the normal pressure immersion method in which the wood material 1 is immersed in the synthetic resin liquid under normal pressure, and the immersion method in which the wood material 1 is immersed in the synthetic resin liquid under reduced pressure, and then immersed in the synthetic resin liquid under normal pressure or pressurization. It is possible to adopt a reduced pressure normal pressure method or a reduced pressure pressurization method in which the sample is immersed in water. By these impregnating operations, the synthetic resin 2 not only penetrates into the inside of the wood material 1 but also covers the entire surface of the wood material 1 and fills the inside of the conduit 3.
合成樹脂２を含浸後、木質材料１を溶剤で洗浄して、同
図（Ｂ）に示すように木質材料１の表面に付着した合成
樹脂および導管３内に充填された合成樹脂を除去する。After impregnating the synthetic resin 2, the wooden material 1 is washed with a solvent to remove the synthetic resin attached to the surface of the wooden material 1 and the synthetic resin filled in the conduit 3, as shown in FIG.
溶剤としては、合成樹脂２を溶解するものが使用され、
たとえばスチレン、アセトン、メチルエチルケトン等が
あげられる。As the solvent, one that dissolves the synthetic resin 2 is used,
Examples include styrene, acetone, methyl ethyl ketone, and the like.

１の表面に着色合成樹脂４（クリヤーを含む）を塗布し
て、同図（Ｃ）に示すように導管３にこの着色合成樹脂
４を充填させ、この状態で着色合成樹脂４を完全硬化さ
せる。After cleaning with a solvent, the wood material 1 is heated in a dryer to harden, preferably semi-harden. Next, a colored synthetic resin 4 (including clear) is applied to the surface of this wood material 1, and the colored synthetic resin 4 is filled into the conduit 3 as shown in FIG. 4 is completely cured.
ついで１、同図（Ｄ）に示すように、木質材料１の表面
に付着した着色合成樹脂４をサンプ等により研摩して除
去し、表面塗装を施して仕上げる。1. As shown in FIG. 1D, the colored synthetic resin 4 adhering to the surface of the wood material 1 is removed by polishing with a sump or the like, and the surface is finished by painting.
このように構成したため、含浸処理する合成樹脂１がた
とえ着色されていないクリヤーなものであったとしても
、様々な色に着色した着色合成樹脂４を木質材料ｌに塗
布し導管３内に充填させることにより、様々な色に着色
された着色化粧板を簡単につくることができる。With this structure, even if the synthetic resin 1 to be impregnated is a clear, uncolored material, colored synthetic resins 4 colored in various colors can be applied to the wooden material 1 and filled into the conduit 3. By doing so, colored decorative boards colored in various colors can be easily produced.
