Decorative sheet and method for manufacturing decorative sheet
Provided are: a decorative sheet which has a glossiness of 15 or less, excellent designability, fingerprint resistance, high durability (particularly scratch resistance and stain resistance), and processability (which is easily laminated to a substrate and is unlikely to break); and a method for producing the decorative sheet. This decorative sheet (1) is provided with a raw material layer (2) and a surface protection layer (5), the glossiness of the surface protection layer (5) is 15 or less, the surface of the surface protection layer (5) has ridge-shaped parts protruding in a ridge-shaped manner and has an uneven shape, and the Martens hardness of the surface protection layer (5) is in the range of 20 N/mm2 to 200 N/mm2. The main material of the surface protection layer (5) is an ionizing radiation-curable resin, the main component of the ionizing radiation-curable resin is a tetrafunctional acrylic resin including a repeating structure, the number of repetitions of the repeating structure is 12 or more, and the RSm/Ra of the uneven shape of the surface protection layer (5) is in the range of 10-300.
提供光泽度为15以下的具有优异的设计性，并且具有耐指纹性、高度耐久性(特别是耐伤性和耐污染性)以及加工性(容易层压至基材且难以发生破裂)的装饰片及其制造方法。本实施方式涉及的装饰片(1)具备原材层(2)和表面保护层(5)，表面保护层(5)的光泽度为15以下，表面保护层(5)的表面具有以脊状突出而设置的脊状部、并且形成有凹凸形状，表面保护层(5)的马氏硬度在20N/mm2以上200N/mm2以下的范围内，表面保护层(5)的主要材料为电离放射线固化性树脂，该电离放射线固化性树脂的主要成分为包含重复结构的4官能的丙烯酸树脂，该重复结构的重复次数为12以上，表面保护层(5)的凹凸形状的RSm/Ra在10以上300以下的范围内。
