A decorative paper having a printed layer formed on a base material such as MDF is laminated, and if necessary, a layer of OP varnish or a resin such as urethane, polyester, amino alkyd is formed. Usually, when manufacturing such a decorative board, it is designed such that the color of the base material is concealed by the concealing power of the decorative paper itself by sticking decorative paper, and the original color of the decorative paper itself is expressed. However, decorative paper is often impregnated with a resin, and its hiding power must be insufficient. In addition, the color tone of the base material usually varies depending on the lot even for products of the same maker, and there is a considerable difference in the color tone between different manufacturers. Therefore, a concealing layer is formed on the base material to conceal and block the color of the base material and to make the surface color of the decorative plate uniform.

As described in JP-A-5-116103, a concealing layer is provided by applying a vinyl acetate adhesive mixed with a pigment on the surface of a base material, and a decorative veneer is provided on the concealing layer via a resin-impregnated sheet. Forming a concealing layer with a coating composition in which a concealing pigment such as titanium oxide is mixed with a vinyl acetate resin on the surface of the base material,
A decorative paper is laminated on the concealing layer with an adhesive (prior art 2) to prevent the color of the base material from being transparent on the surface.
