It is also preferable to make use of the natural color of the wood, such as the white color of beech. Coloring treatment is performed by dissolving a colorant such as a dye or pigment in a solvent such as water or an organic solvent at a concentration of 0.
A method is used in which a large number of small pieces of wood are immersed in a four-color liquid with a concentration of about 1 to 10 percent. It is also possible to heat the coloring liquid to promote penetration of the coloring liquid, thereby producing a deep color. Further, during the dimensional stabilization treatment, a coloring agent can be dissolved in various liquid resins, and the coloring treatment can be performed simultaneously with the dimensional stabilization treatment.

After mixing and kneading small pieces of wood with this resin composition, this mixture is formed into a flat plate shape, and heated and pressed using a hot press or the like to form a solidified product. Next, the surface of this solidified product is ground by sanding or the like to expose the small pieces of wood on the surface, thereby forming the colored opaque resin layer 4 containing dispersed wood pieces. Next, a colorless transparent or colored transparent paint such as unsaturated polynisder resin is applied to the surface of this to form a transparent resin layer 5, and this is adhered to the substrate 1 to form a decorative board.

20IMR1 was cut into small pieces with a thickness of 1 to 1.5 m, and after drying, the pieces were immersed in an uncured unsaturated polyester resin solution, impregnated with the resin solution, and left at room temperature to form a semi-cured state. Small pieces of wood were mixed with the above composition, poured into a mold, and leveled with a roller to form a flat plate with a thickness of 1.5all. Next, this was allowed to stand at room temperature for 3 hours, and then heated and pressed in a hot press at a pressure of 1 HPa and a degree of thirst of 100° C. for 5 minutes to form a solidified product. This material was sanded and ground to expose small pieces of wood on the surface. Next, apply an unsaturated polyester resin paint to the surface of this to a thickness of approximately 1.
A coating film with a thickness of 00 μm was formed, and this was bonded to a substrate of lauan plywood with a thickness of 2 alI to obtain a decorative board.
