ABSTRACT:
The front surface of a wooden overlay sheet, having a wooden material on the front surface thereof, is subjected to a color treatment with a colorant comprising a primer resin; the wooden overlay sheet, which was subjected to color treatment, is positioned in a metal mold for molding, and a transparent resin layer is molded on the front surface thereof by means of injection-molding. Furthermore, a synthetic resin core material is molded on the rear surface of the wooden overlay sheet. A composite molded article is thereby produced, wherein a synthetic resin core material is molded on the rear surface of the wooden overlay material, and a transparent resin layer is molded on the front surface of the wooden overlay sheet. Thus, the present invention enables the enhancement of the outer appearance of the product and the enhancement of the adhesion of the wooden overlay sheet and the transparent resin layer.
