Abstract

PURPOSE:To enable luster movement, solid feelings, and depth feelings to be performed by integrally laminating a specific base material sheet and top sheet by specific means. CONSTITUTION:Ink 4 having brightness is printed on the surface of a colored polyvinylchloride film 3 in a set solid manner. The set solid printed sheet is heated to 120 deg.C for softening resin, and then given embossed patterns thereon at the roll surface temperature of 20 deg.C by means of an embossing machine installed with a natural bark embossing roll, and thus a base sheet is manufactured that has recessions and protrusions on its surface. On the recessed and protruded surface 5 of the base sheet, coating is effected with transparent resin 6 only by a sufficient quantity of burying the recessions and protrusions therein. On the other hand, on the surface of the transparent polyvinylchloride film 1, the grain patterns 2 of wood are printed by the use of a gravure ink. The printed surface of the grain patterns printed sheet and gravure coated surface of the precedingly obtained base sheet are faced to each other, and then the both sheets are laminated by a dry laminate sheet method.

In the decorative material of the present invention, a normal embossing method can be used to impart an uneven shape to the surface of the base sheet. It is preferable to use a resin bottle molded from the surface of a log or an electroformed embossed plate made from the resin bottle. However, it is also possible to use a plate obtained by etching a pattern obtained by photographing the exposed areas of raw wood. Other preferred uneven shapes include hairlines, line-like embossed parallel straight sections, or groove-like unevenness such as parallel wavy curved sections such as sinusoidal curves, Bessel function curves, cycloidal curves, and elliptic function curves. (A collection of uneven shapes including the parallel straight lines or curved lines in a closed curve area, where the total angle formed by the directions of the straight lines or curved lines that are adjacent to each other through the boundary between any two areas is (You may also use one with a different shape.) Furthermore, CAD:CAM is applied so that the spatial frequency spectrum of the cross-sectional curve becomes a 1/f type spectrum inversely proportional to the frequency f, as described in, for example, Japanese Patent Application Laid-Open No. 2-41500.
It may be designed and processed. Since the unevenness of an actual wood grain pattern is spectrally included in the shape of this 1/f type spectrum, it is particularly preferable for reproducing natural wood.
