ｍ程度に形成することが好ましい。In the present invention, first, as shown in FIG. 1, a liquid or paste thermoplastic resin composition is applied onto a support material 1 to form a resin coating layer 2. Examples of the supporting material 1 include thin paper, roll paper, high-quality paper, kraft paper, coated paper, and other papers, various synthetic resin films or sheets, metal foils such as aluminum, and other above-mentioned papers and resin films or sheets and metals. A laminated film or sheet in which two or more types of foils are arbitrarily laminated can be used. The support material 1 can also be printed if necessary. The liquid or paste thermoplastic resin composition to be applied onto the support material 1 may be, for example, a paste made by adding and kneading a plasticizer, a heat stabilizer, a filler, a pigment, etc. to vinyl chloride resin, or a thermoplastic resin. Emulsion paints, water-based paints, oil-based paints, etc. are used. Thermoplastic resins used in emulsion paints, water-based paints, oil-based paints, etc. include vinyl acetate resin, ethylene-vinyl acetate resin, acrylic resin, methacrylic resin, amide resin, thermoplastic ester resin, cellulose resin, etc. Can be mentioned. A foaming agent, a cell regulator, a viscosity reducing agent, etc. can be added to the above thermoplastic resin composition as necessary, and if a foaming agent is included, unevenness with a larger difference in height can be added. A pattern is formed. These liquid or paste thermoplastic resin compositions are coated on the supporting material 1 by roll coating, gravure coating, flow coating, doctor knife coating, comma coating, air knife coating, etc.! ! 1 cloth and 1 layer of resin coating 2
is formed, but the resin coating layer 2 has a thickness of 0.1 to 1.0
It is preferable to form it to about m.

半固化せしめた後）。Next, while the resin coating layer 2 is in a semi-solidified state (for example, when a liquid resin composition such as an emulsion paint is applied, or even when a paste-like resin composition is applied, the resin composition has a low viscosity). (after the resin coating layer 2 is semi-solidified by heating etc.).

とができる。An uneven pattern is formed on the two surfaces of the resin coating layer. As a method for forming the uneven pattern, it is possible to use a conventional embossing plate, but it is also possible to use a conventional embossing plate.
3... and a plurality of needle-like protrusions 5. as shown in FIG. It is preferable to use a combination of rolls 6 and the like having . and ., and in this case, the pattern of the uneven pattern to be formed can be easily changed.

て複雑な凹凸模様を容易に形成することができる。That is, for example, when using the comb-like body 4, as shown in FIG. When pressed against the resin coating layer 2, a linear uneven pattern is formed, and at the same time, when the comb-like body 4 is moved laterally (in the direction of arrow B), a wavy uneven pattern is formed. The depth of the concave-convex pattern can be changed by moving the embossing plate, and by arbitrarily combining these methods, the same pattern will not be repeated at predetermined intervals, as is the case when using an embossing plate. It is possible to easily form a richly varied uneven pattern, and there is no need to prepare multiple types of expensive plates to form different patterns, unlike when using an embossed plate, resulting in a beautiful and varied pattern. It is possible to form a concavo-convex pattern with an inexpensive method. Further, each tooth portion 3゜3... of the comb-like body 4 has a different length, each tooth portion 3,
3... by having different front and back positions with respect to the sheet transport direction, or by configuring each of the enlarged teeth parts 3, 3... to be movable independently in vertical, horizontal, etc. directions. Complex uneven patterns can be easily formed.

Even when using a roll 6 having ..., the projections 6, 5 ... can be pressed against the resin-coated ff12 surface while rotating the roll 6, and the change can be made by further moving the roll 6 up and down and left and right. A rich uneven pattern can be formed.

Press the teeth of the shaped body against the surface of the U fat coating layer, and then heat at 220°C.
The resin coating layer was heated for 60 seconds to foam and completely solidify the resin coating layer. The surface of the obtained decorative sheet had a striped concavo-convex pattern formed at 20 m intervals and had a beautiful appearance.

きる効果を有する。As explained above, in the present invention, a resin coating layer formed by coating a liquid or paste thermoplastic resin composition on a support material forms an uneven pattern on the coating layer while it is in a semi-solidified state, and then the resin The advantage of using a method that completely solidifies the coating layer is that the uneven pattern can be formed at the same time during the manufacturing process of the laminated sheet, and the uneven pattern can be formed in a separate process after manufacturing the laminated sheet as in the conventional method. The present invention has the effect that a decorative sheet having a beautiful uneven pattern without any annoying shank can be efficiently produced.
