［従来の技術］
従来から基板の表面に水溶性接着剤を介して化粧紙を高
温高圧のプレスで圧締して貼着する化粧板の製造方法が
提供されていた。[Prior Art] Conventionally, a method for manufacturing a decorative board has been provided in which decorative paper is pressed and adhered to the surface of a substrate via a water-soluble adhesive using a high-temperature, high-pressure press.
しかし、水溶性接着剤を塗布した基板上面に化粧紙を載
置すると、化粧紙が接着剤中の水分を吸水してしまうた
めて化粧紙がカールしたりシワとなるなどの問題を生じ
ていた。However, when decorative paper is placed on top of a substrate coated with a water-soluble adhesive, the decorative paper absorbs the moisture in the adhesive, causing problems such as curling and wrinkles. .
そこで、このような化粧板に用いる化粧紙は、化粧紙の
隠蔽性を向上させたり、吸水性を抑えるために填料を多
（含み、多いものでは３０％以上を、少ないものでも１
０％以上は含んでいるものが提供され使用されてきた。Therefore, the decorative paper used for such decorative boards contains a large amount of filler (more than 30%, and at least 1% filler) in order to improve the concealing properties of the decorative paper and suppress water absorption.
Products containing 0% or more have been provided and used.
［発明が解決しようとする課題］
所が、化粧紙の隠蔽性を向上させたり、吸水性をある程
度抑えることはできるが、填料は化粧紙を形成する繊維
間に存在して繊維間を押し広げたり、また、比重が高く
紙料の抄造時に紙料と均一に混ぜ合わせることが困難な
ため、化粧紙の強度を弱めるという問題を生じていた。[Problem to be solved by the invention] However, although it is possible to improve the hiding power of decorative paper and to suppress water absorption to some extent, the filler exists between the fibers that form the decorative paper and pushes the fibers apart. In addition, due to its high specific gravity, it is difficult to mix it uniformly with the paper stock during paper making, resulting in the problem of weakening the strength of the decorative paper.
また、填料自体に吸湿性があるため、多量に混和すると
填料自体が吸湿した水分によって化粧紙にシワやカール
が生じることもあった。Furthermore, since the filler itself is hygroscopic, if a large amount is mixed in, the moisture absorbed by the filler itself may cause wrinkles or curls in the decorative paper.
一方、合成樹脂系エマルジョンのみを、混和すると、耐
水性を向上させることができるが、接着剤分子の滲み込
みが悪く、接着剤を介して基板等へ接着する場合に接着
不良となることもあった。On the other hand, if only a synthetic resin emulsion is mixed, water resistance can be improved, but the penetration of adhesive molecules is poor, which may result in poor adhesion when adhering to a substrate etc. via an adhesive. Ta.
