OBLIQUE SHEET MATERIAL, AND PRODUCTION METHOD OF OBLIQUE SHEET MATERIAL

To provide an oblique production material having a gradual change part where a height of a recessed part from its bottom gradually changes from the recessed part to a non-recessed part, achieving gradation from the recessed part to the non-recessed part.SOLUTION: The sheet material 1 is provided with a recessed part 3 and a non-recessed part 4 on a surface side of a cushion substrate 2. From the recessed part 3 over the non-recessed part 4, a gradual change part 5 where a height H of the recessed part 3 from its bottom 3a gradually changes is provided. An obtuse angle face portion 6a may be provided on the side of bottom 3a of the recessed part 3 of the gradual change part 5, and a wide angle face portion 6b may be provided on the side of the non-recessed part 4 of the gradual change part 5. Moreover, in the production method for producing the sheet material 1, an embossing gradual change part 14 where a depth D from an apex 11a of an embossing projecting part 11 gradually changes is provided from the embossing projecting part 11 over the non-embossed projecting part 12, and the embossing mold material 13 is pressed while the embossing projecting part 11 and the embossing gradual change part 14 are being in contact with a surface side of the cushion substrate 2.SELECTED DRAWING: Figure 1 【課題】凹部から非凹部までに亘って凹部の底からの高さが漸次変化する漸変部を有する等して、「凹部から非凹部にかけてのグラデーション」などを実現する。【解決手段】クッション基材２の表面側に凹部３と非凹部４が形成されたシート材１である。凹部３から非凹部４までに亘って、凹部３の底３ａからの高さＨが漸次変化する漸変部５を有している。漸変部５の凹部３の底３ａ寄りに鈍角面部分６ａが形成されたり、漸変部５の非凹部４寄りに広角面部分６ｂが形成されていても良い。又、上述のシート材１を製造する製造方法では、エンボス凸部１１から非エンボス凸部１２までに亘ってエンボス凸部１１の頂１１ａからの深さＤが漸次変化するエンボス漸変部１４を設け、エンボス凸部１１及びエンボス漸変部１４がクッション基材２の表面側に当接した状態で、エンボス型材１３を押圧する。【選択図】図１
