    • There is provided a decorative material that gives the impression of unevenness due to the differences in gloss of a film formed on the surface of the decorative material. This decorative material is excellent in solvent resistance; a pattern formed on it is not easily erased even when the decorative material is wiped with cloth or the like impregnated with a solvent. Such a decorative material can be produced in the following manner: a coloring layer 3 and a pattern layer 4 are formed on the surface of a substrate 2 in the order mentioned; and, before forming a surface-protective layer 7 by the use of an ionizing radiation hardening resin composition, a coating layer 5 capable of preventing the penetration of the ionizing radiation hardening resin composition into the underlying layers is formed on the pattern layer 4 by using a hardening resin, and a highly permeable pattern layer 6 having permeability for the ionizing radiation hardening resin composition higher than that of the underlying coating layer 5 is provided on top of the coating layer 5 by the use of a hardening resin.
    • 提供了由于在装饰材料的表面上形成的膜的光泽差异而产生不均匀性的装饰材料。 该装饰材料耐溶剂性优异; 即使当装饰材料用溶剂浸渍的布等擦拭时,形成在其上的图案也不容易擦除。 这样的装饰材料可以按以下方式制造:在基板2的表面上以所述顺序形成着色层3和图案层4; 并且在通过使用电离辐射硬化树脂组合物形成表面保护层7之前,可以通过使用在图案层4上形成能够防止电离辐射硬化树脂组合物渗透到下面的层中的涂层5 通过使用硬化树脂,在涂层5的顶部设置硬化树脂和对电离辐射硬化树脂组合物具有比下层涂层5高的渗透性的高渗透性图案层6。
