である。2. Description of the Related Art Conventionally, a decorative sheet used for the above purpose has a solid ink layer or a pattern ink layer provided on a film or paper base sheet, if necessary, and is coated with a curable resin and then coated. The surface thus obtained was pressure-bonded to a concavo-convex roll, and heating, radiation irradiation and the like were performed from the back surface of the substrate sheet to cure the resin. The decorative sheet according to this manufacturing method is characterized in that a concavo-convex pattern is formed on the surface simultaneously with the curing of the curable resin.

応力は、凹凸の形状、版深によっても異なってくるが、
複雑で込み入った柄や版深の深いものは剥離し難く、逆
に凹凸型の面がフラットに近いほど剥離し易くなる。The load stress for peeling the substrate sheet from the uneven roll varies depending on the shape of the unevenness and the plate depth.
It is difficult to peel off a complicated and complicated pattern or a deep plate, and conversely, the flatter the uneven surface is, the easier it is to peel off.

っていた。In the conventional concavo-convex roll, a concavo-convex mold is formed on the entire length of the surface. Therefore, in a complicated uneven pattern roll with a deep pattern and a deep plate, the load stress of peeling between the uneven roll and the base sheet becomes large, and in the case of a base sheet (paper) with weak inter-paper strength, the cause of paper breakage It was.

でかえって負荷応力が大きくなってしまう。A method and apparatus for providing smooth portions on both ends of a roll is disclosed in Japanese Patent Publication No. 5-58788, but regarding the height of the smooth portion (roll diameter), the convex portion of the uneven portion is used. Is said to be the same as or lower than the height of the flat surface. However, in this method, the pattern area of the concavo-convex pattern exceeds 50% or when the plate depth of the concavo-convex pattern is shallow, but the pattern area is less than 50% of the whole like the concavo-convex pattern of the wood grain pattern. Case, or the plate depth is 50μ
In the case of exceeding m, if the height of the uneven portion is the same as or lower than that of the flat surface, the load stress rather increases at the boundary between the uneven portion and the flat surface.
