PURPOSE:To obtain a decorative board generating no fine wrinkles, by printing a grain pattern on the surface of the plastic film of a specific composite sheet and further bonding a decorative sheet to the printed surface through an adhesive. CONSTITUTION:A decorative sheet 6 is formed from a composite sheet 10, which is constituted of paper 1 having a basis wt. of 20-70g/m<2> and a smooth surface, an olefinic resin 2 having a thickness of 10-30mum and a plastic film 3 having a thickness of 5-30mum, the grain pattern 4 printed on the surface of the film 3 by transparent ink and the transparent adhesive varnish layer 5 applied to said pattern 4. This decorative sheet is laminated to a wooden base material through an adhesive 7 so as to turn the grain pattern formed surface toward said base material. After the adhesive 7 is cured, the paper 1 and the resin 2 (the laminate of 1, 2 is said to be a backing sheet layer) are released to obtain a decorative board. By the close adhesion of the backing sheet layer and the printed sheet layer, lamination can be performed without generating fine wrinkles. |
