Coating layer 16 and a number of transparent or translucent layers provided on the coating layer and spaced by a thermosetting resin having a higher gloss than the resin of the coating layer 16 or a radical-polymerized high-solids resin. And the surface layer 20 in which the outline of the pattern (FIGS. 2 and 3) is represented by the raised portion 18.
[0007]
The upper portion 18 is spaced a certain distance b (FIGS. 4, 5, 6 and 8) from the adjacent upper portion, but is partially, that is, has a pattern such as a wood conduit 19 as shown in FIG. In order to express the contour by not providing a raised portion, an interval larger than the interval b is set. Similarly, when the contour of the pattern such as the stone pattern 21 is represented by the raised portion 18 as shown in FIG. 3, that is, when the stone pattern 21 is represented by not providing the raised portion around, The distance between the handle and the handle is larger than the distance b.
[0008]
In the case of the example of FIG. 2 in which the contour of the conduit is represented by the raised portion 18 on the surface layer 20, a wood grain pattern is printed on the printed layer 14. In the case of the example of FIG. 3 in which the contour of the stone is represented by the raised portion 18 on the surface layer 20, a stone pattern is printed on the printing layer 14. There is no need to match the pattern as described above between the print layer 14 and the surface layer 20, and an abstract pattern may be printed on the print layer and a contour of a stone pattern may be displayed on the surface layer.
[0009]
The substrate 12 is a polyester film, a thermoplastic saturated polyester film, a polyacrylonitrile film, a polyimide film, a polyester imide film, a polyether ketone film, a polysulfone film, a polycarbonate film, a polyether sulfone film, or a polyphenylene sulfide. A film, a fluorine film, a thermoplastic polyurethane film, a nylon film, an acrylic film, a polyvinyl alcohol film, a polypropylene film, a biodegradable film, a synthetic paper, a metal stay, a nonwoven fabric, paper, or a vinyl chloride film.
[0010]
Further, the printed layer 12 is printed with a solid color printing or a pattern such as a wood pattern, a stone pattern, or an abstract pattern.
