The present invention improves a surface protective layer in the resistance to marring to the extent not achieved even if the surface protective layer is made of a crosslinked cured product of an ionizing radiation-curable resin and added with silica. When forming a layer comprising the crosslinked cured product of the ionizing radiation-curable resin as a surface protective layer (2) on a substrate sheet (1) made of paper or the like, fired kaolin is contained as a filler in the surface protective layer. The fired kaolin is preferably surface-treated with a silane coupling agent. On the substrate sheet (1), a wholly solid layer (3) and a pattern layer (4) are generally provided. A primer layer may be optionally provided between the substrate sheet and the surface protective layer.
