This will be described below.
本発明で用いる木質繊維板は、特に制限されず、市販のものを使用することができる。一般に木質繊維板は、植物繊維等を主原料として結合剤等を添加し、圧縮成型されるものである。例えば、0.35ｇ/cm3程度以下の低密度繊維板（ＬＤＦ）、0.35〜0.8ｇ/cm3程度の中密度繊維板（ＭＤＦ）、0.8ｇ/cm3程度以上の高密度繊維板（ＨＤＦ）のほか、パーティクルボード等が挙げられる。これらの中でも、ＭＤＦが好ましい。 The wood fiber board used in the present invention is not particularly limited, and commercially available ones can be used. In general, a wood fiber board is compression-molded by adding a binder or the like using vegetable fiber or the like as a main raw material. For example, 0.35 g / cm 3 of about or lower density fiberboard (LDF), 0.35~0.8g / cm 3 order of medium density fiberboard (MDF), 0.8g / cm 3 of about or more high-density fiberboard (HDF) In addition, particle boards and the like can be mentioned. Among these, MDF is preferable.
上記木質繊維板の主原料としては、例えば、杉、松、檜、カラ松、赤松、トド松等の針葉樹、ラワン、カポール、ポプラ、ヤナギ、欅等の広葉樹などが挙げられる。 Examples of the main raw material for the wood fiber board include conifers such as cedar, pine, cocoon, Kara pine, red pine, and todo pine, and broad-leaved trees such as lauan, capol, poplar, willow, and oak.
また、これらは、これらはチップ状で圧縮成型されたものであってもよく、繊維状で圧縮成型されたものであってもよい。 In addition, these may be chip-shaped and compression-molded, or may be fiber-shaped and compression-molded.

For example, in addition to water pressure transfer such as curl fit, PET film transfer and the like can be mentioned. The ink to be transferred may be colored so as to synchronize with the unevenness of the wood grain pattern.
以下に実施例を示し、本発明をより具体的に説明する。但し、本発明は実施例に限定されない。 Hereinafter, the present invention will be described in more detail with reference to examples. However, the present invention is not limited to the examples.
実施例１
木質繊維板として、中密度繊維体（「Mタイプ」、セイホク（株）製）縦2400ｍｍ×横1200ｍｍ×高さ（厚み）6ｍｍを用いた。
Example 1
As the wood fiber board, a medium density fiber body (“M type”, manufactured by Seyoku Co., Ltd.) length 2400 mm × width 1200 mm × height (thickness) 6 mm was used.
この木質繊維板の上面から、木目導管模様賦型用のエンボス版を押圧することにより、木質繊維板の上面に木目導管模様の凹凸を付した。 By pressing an embossed plate for forming a wood grain conduit pattern from the top surface of the wood fiber board, the top surface of the wood fiber board was provided with irregularities in a wood grain conduit pattern.
次いで、水性ウレタン塗料（「ドルフィン」、サンユーペイント（株）製）を上記木質繊維板表面に塗布した後、ドクターロールにて、表面の凹部以外のインキを掻き取り、凹部に着色インクを形成させて、所望の木質繊維板を製造した。
Next, after applying a water-based urethane paint ("Dolphin", manufactured by Sanyu Paint Co., Ltd.) to the surface of the above-mentioned wood fiberboard, the doctor roll scrapes off ink other than the recesses on the surface to form colored ink in the recesses. Thus, the desired wood fiberboard was manufactured.
