。A plurality of wood veneers are laminated with adhesive, pressed and tightened to form a 7-rich flitch, and this flitch is sliced in a direction that intersects with the lamination direction to form each wood-quality wood board. The wood material veneer used in the method for manufacturing a decorative veneer for obtaining a finished decorative fist whose cut surface resembles an annual ring layer imparts a hue resembling that of natural wood to the reproduced wood grain pattern. It is customary to dye the material in a predetermined color before the lamination process.

Apply colored adhesive etc. to the material color and assemble 7 rich→
When expressing a summer wood layer with the cut surface made of the colored adhesive on the wood grain pattern reproduced on the wood surface of the laminated decorative veneer obtained through the slicing process, the summer wood colored adhesive is applied to the spring wood material single layer. If the shading is applied to the board 4 in a band-like manner as shown in FIG. 3, the shading distribution of the reproduced summer wood layer will become regular, resulting in the shading similar to that of the natural material 5 shown in FIG. 2. In order to avoid this, the colored adhesive 6 for the dark colored portion of the summer material is applied to the spring material veneer 4' as shown in Figure 4. Colored adhesive for dark colored areas of summer material6
This is a dispersion coating processing method that can easily perform random dispersion coating, and an example thereof is shown in the SS diagram.
