More specifically, it is possible to conceal defects in the appearance of the base material, and can be recovered and reused as paper resources. Colored paper for printed decorative boards that suppresses appearance defects due to impurities and pitch contained in the base material About.
従来、建築内装材等の建材に使用される化粧板は、合板、中密度繊維板、パーティクルボード等の基材表面に、絵柄模様が印刷された化粧紙やプラスチックフィルム化粧シートを貼り合わせて製造されている。 Conventionally, decorative boards used for building materials such as building interior materials are manufactured by pasting decorative paper or plastic film decorative sheets printed with a pattern on the surface of base materials such as plywood, medium density fiberboard, and particle board. Has been.
建材用化粧板の基材には、木質基材が通常使用される。木質基材を用いた化粧板は、吸湿性が良い等の長所を有する。また、木質基材の持つ木目模様は意匠性に優れる。一方、木質基材には局所的な色ムラや節模様等外観上の欠陥があり、これらは意匠性を損なう。 As the base material of the decorative board for building materials, a wooden base material is usually used. A decorative board using a wooden substrate has advantages such as good hygroscopicity. Further, the wood grain pattern of the wood base material is excellent in design. On the other hand, the wooden substrate has defects in appearance such as local color unevenness and knot patterns, which impair the design.
木質基材の外観上の欠陥を隠蔽する技術として、木質基材、接着剤層、化粧層(半透明層とインクジェット印刷層)からなる化粧板が提案されている(特許文献1)。この提案では、木質基材の欠陥を適度に隠蔽すると共に、木目模様を視認できる程度の半透明性の紙質材を設けることにより木質基材本来の意匠性を生かそうとするものである。 As a technique for concealing defects on the appearance of a wooden substrate, a decorative board made of a wooden substrate, an adhesive layer, and a decorative layer (semi-transparent layer and inkjet printing layer) has been proposed (Patent Document 1). In this proposal, a defect of the wood base material is appropriately concealed and a semi-transparent paper material that can visually recognize the wood grain pattern is provided to make use of the original design of the wood base material.
しかしながら、この提案の化粧板では木質基材欠陥の隠蔽が不充分である。更に、木質基材に含まれるヤニ成分が化粧板表面へ滲み出すことによる外観不良を防止できない。 However, the proposed decorative board is insufficient in concealing the wood substrate defect. Furthermore, it is not possible to prevent a poor appearance due to the spear component contained in the wooden base material oozing out to the surface of the decorative board.
木質基材に含まれるヤニ成分による外観不良を防止する技術としては、例えば、基材、接着剤層、化粧材、化粧層で構成され、化粧材が紙質材、樹脂層、紙質材から構成される化粧板が提案されている(特許文献2)。この提案では、紙質材の中間に樹脂層を設けることにより、木質基材中のヤニ成分が化粧板表面へ滲み出すことを防止している。 As a technique for preventing appearance defects due to the spear component contained in the woody base material, for example, it is composed of a base material, an adhesive layer, a decorative material, and a decorative layer, and the decorative material is composed of a paper material, a resin layer, and a paper quality material. A decorative board has been proposed (Patent Document 2). In this proposal, a resin layer is provided in the middle of the paper material to prevent the spear component in the wooden base material from seeping out to the surface of the decorative board.
しかしながら、この提案の化粧板は、化粧材の構成成分として樹脂を用いるため、化粧板が高価になる。また、紙質材を紙資源として回収再使用することが困難となる。更に、紙質材中に含まれる夾雑物やピッチ分による化粧板の外観不良を防止できない。
本発明の課題は、上記問題を解消でき、紙質材を回収再使用することが容易で、紙質材中に含まれる夾雑物やピッチ分による化粧板の外観不良を防止でき、更に木質基材表面の色相ムラや節模様等の欠陥を隠蔽できる化粧板用着色紙を提供することである。 The problem of the present invention is that the above problems can be solved, the paper material can be easily recovered and reused, the appearance of the decorative board due to the impurities and pitch contained in the paper material can be prevented, and the surface of the wooden substrate It is intended to provide a colored paper for a decorative board capable of concealing defects such as uneven hue and knot pattern.
