A method of forming irregularities on a substrate sheet on which a pattern is applied by using an embossing roll, an embossing template, or the like; (2) Visually applying a matte conduit print or the like on the substrate sheet in a decorative manner. (3) forming a printed portion such as a conduit for forming a concave surface on a substrate sheet on which a pattern is formed with an ink containing a lyophobic agent,
A method of forming a concave portion by applying a transparent resin thereon and making the printed portion of the conduit or the like liquid-repellent, or (4) forming a printed portion of the conduit or the like with foaming ink, polishing by heating and foaming. A method of forming a concave portion is known, and all of these methods apply an uneven pattern to the surface of a base sheet made of paper, a synthetic resin sheet such as vinyl chloride, acrylic, or the like, and attach it to a substrate. As a result, it is produced as a decorative material having a design with a concavo-convex pattern on the surface, and there is a problem that water resistance, weather resistance, heat resistance, and the like are poor.

Also, without using the above-described base sheet, a pattern such as a grain or a conduit is directly printed on the substrate by the same method as in the above (2), or the grain or the pipe is printed by a normal pattern printing. Although it is conceivable to form a concave portion by the method (3) or (4) on the surface expressing a conduit or the like, in the case of direct printing, the smoothness and printability of the substrate itself are determined with respect to the above-mentioned base material sheet. In general, the design is inferior, so the design of the picture is not good, and the production efficiency at the time of printing the picture is very poor.

Those having a peeling effect by themselves can be used as they are, while those having no peeling effect by themselves are provided with a peeling layer by a usual method. In addition, in the transfer sheet 7 of FIG. 3A, the pattern layer 4 is the outermost layer, but the adhesive 3 may be added on the pattern layer 4 as needed. The reason why the adhesive layer 3 is not required is that the picture layer 4 may be capable of imparting adhesiveness to itself, and the other reason is that the decorative sheet substrate 2 on the side to which the picture is transferred is used. This is because the adhesive layer 3 may be provided on the surface.

The picture layer 4 is printed with, for example, wood grain, stone grain, surface pattern of natural leather, cloth grain, abstract pattern, and the like, and an acrylic vehicle is used as an ink vehicle for forming the arbitrary pattern. A general-purpose resin made of a resin, a urethane resin, a vinyl chloride resin, or the like is used. Also picture layer 4
