様を形成することは困難であった。2. Description of the Related Art Conventionally, a decorative plate made of a thermosetting resin having an uneven pattern on its surface includes an uneven pattern formed by an embossing die or a resin uneven plate.
There is a sheet in which a concavo-convex pattern is formed by a shaping sheet (see Japanese Patent Publication No. 2-38398). But etching,
When using an embossed mold with a fine uneven pattern formed on the surface by sandblasting, engraving, etc., when manufacturing a thermosetting resin decorative board, expensive molds and spare Mold is required, and the cost burden increases. In addition, it is necessary to change the mold at the time of changing the pattern, which significantly increases the manufacturing cost and makes the product expensive. In the case of a resin uneven plate, it is necessary to sandwich a plastic film such as an aluminum foil, a polypropylene, or a polyester between the mold plate and the thermosetting resin decorative plate, since the decorative plate is difficult to peel off. However, it was difficult to form a fine uneven pattern.

For example, using a shaped sheet in which a fine uneven pattern is formed on a thermoplastic resin film, even if an attempt is made to produce a thermosetting resin decorative board, the heat resistance and pressure resistance are inferior to the hot pressure during the production of the decorative board. Therefore, it is not possible to maintain the uneven pattern,
Surface irregularities disappear. Also, even if the melting point is high,
Due to the plastic flow of the resin, the shaping sheet and the decorative board are likely to be in a fused state, and it is difficult to peel off the shaping sheet. Further, the shaping sheet used once cannot be used repeatedly.

８回〜１０回程度繰り返し使用することができる。According to the present invention, a shaping sheet having a fine (depth 1 to 60 .mu.) Irregular pattern on the surface can be obtained, and the visual effect can be obtained by using the shaping sheet. A decorative board having a fine uneven pattern excellent in the above can be obtained. Also, since the shaping sheet is in the form of a roll,
Heat-press molding can be performed continuously, and it has become possible to efficiently produce decorative boards in a short time. Also, since the release agent is added and mixed in the roll-shaped imprinting sheet, when peeling off the imprinting sheet from the decorative sheet after hot press molding,
Since the peeling is light, it is difficult to damage, and the uneven pattern on the surface is hard to disappear (because it can be molded in a short time at low temperature and low pressure compared to other thermosetting resin decorative boards), the same imprint sheet is repeated 8 times ~ It can be used repeatedly about 10 times.
